The Better Choice – Resinating LLC’s® EIPI Technology

Overview

The decision to select a method for rehabilitating a manhole, pipe or other structure in a wastewater, stormwater or freshwater system is dependent on a number of factors…costs, benefits, warranties, useful life, risks, and social costs among others.

Resinating’s EIPI “Expand-in-Place Integration Technology” Technology, is compared to three rehabilitation options in separate sections below – Trench & Replace”, CIPP and SIPP.  You will see why Resinating’s EIPI Technology is The Better Choice, better than any of these options and any other options as well.  We would be glad to discuss your particular situation with you at your convenience.

Immediately below this Overview section, you’ll find sections on The 47-year History Of Resinating Liners, The Benefits Of EIPI Technology and a section on EIPI Technology Basics.  The EIPI Technology Basics section explains how the patented combination of Resinating Fiberglass Expansion Liners and Resinating’s patented EIPI installation process work together to create the Benefits of EIPI Technology.

Below those sections you will find the three sections that compare the use of EIPI Technology to the use of Trench & Replace, CIPP and SIPP.

One can use the links to the left to go to a specific section of interest OR one can scroll down this entire page Better Choice page to capture the broadest perspective on EIPI Technology.

In the end, we believe that you will believe as we do – that Resinating ‘s EIPI Technology is clearly the best available solution when you need to rehabilitate manholes and pipes to keep them in good working order.

The 47-Year History Of Resinating Liners

Some engineering firms and municipalities believe that because Resinating LLC is a new company, it doesn’t have enough experience…we disagree!

  • Resinating LLC is a “new name” but a “new name” with a long history.
  • Resinating LLC was created when the owner of Associated Fiberglass Enterprises (AFE), Resinating’s sister company, along with its general manager invented what is now referred to as EIPI Technology.
  • AFE has been in the fiberglass business since 1959.
  • AFE began manufacturing fiberglass slip liners in 1975. Since 1975, AFE has sold in the neighborhood of $100,000,000 worth of fiberglass liners manufactured using the same technology and the same fabrication methods that it uses to manufacture Resinating Fiberglass Expansion Liners today. In those 47 years, AFE hasn’t had a single repair claim.
  • Then, why the new “Resinating LLC” name? We wanted to separate the ownership of the patent and marketing functions from the manufacturing and installation operations.
  • As a result, “Resinating LLC” will be the common denominator of what we expect will become a very large business in the months and years to come. Resinating LLC is a “new company” in name only…it dates back to 1959 or 1975, depending on when you start counting.

Resinating Fiberglass Expansion Liners and the Resinating’s Installation Process were awarded a patent in June, 2020, which henceforth has become known as EIPI Technology…a revolutionary breakthrough in the way manholes and pipes are rehabilitated…built on 47 years of liner manufacturing experience.

The Benefits Of Resinating’s EIPI Technology

Let’s start with cost…Resinating’s EIPI Technology is hugely cost-effective.

Depending on a number of considerations, on Day 1, Resinating’s EIPI Technology may be somewhat less costly or slightly more expensive than other options…BUT the important point, is that unlike all other options, the Day 1 cost of EIPI Technology is the only cost one will incur over its 100+ year useful life when Resinating’s EIPI Technology is used to rehabilitate a manhole or a pipe. 

EIPI Technology is 100% leakproof, exceptionally strong and has a 100+ year useful life.

    • With EIPI Technology there won’t be any continuing costs to treat ongoing infiltration, because there won’t be any ongoing infiltration. There won’t be any sinkholes to deal with either…period. 
    • With EIPI Technology there won’t be any emerging structural issues because EIPI Technology has unequalled strength…period.
    • With no infiltration, no structural issues and a 100+ year useful life the manhole, pipe or other structure that is being rehabilitated won’t have to be rehabilitated again…period.

Decade after decade, Resinating’s EIPI Technology will continue to perform perfectly…as they say, one and done.  That is what we mean by EIPI Technology is hugely cost-effective

 As to other major benefits of Resinating’s EIPI Technology:

  • EIPI Technology is trenchless…it can even renew collapsed pipes in many instances.
  • EIPI Technology is warrantied to be leakproof for 20-years…that includes a warranty of both materials and workmanship.
  • EIPI Technology provides an unequalled level of structural integrity.
  • EIPI Technology has a useful life in excess of 100 years because:
    • Resinating Fiberglass Expansion Liners are impervious to corrosion from any chemical or biological agents in waste water, storm water, fresh water and many industrial liquids.
    • Resinating fiberglass is indestructible…it has no fillers, no thin spots, no corrosion potential…it’s just 100% solid, indestructible fiberglass.
  • EIPI Technology eliminates virtually all excavation, traffic congestion, hazardous waste removal, resurfacing and landscaping costs.
  • EIPI Technology has no health risks associated with it, unlike CIPP with its styrene and various VOC’s.
  • EIPI Technology can be installed quickly…a typical manhole can be rehabilitated in a day as can several hundred feet of pipe on a straight run.

These are the major factors along with the fact that EIPI Technology is hugely cost-effective that will propel EIPI Technology forward, displacing virtually all other rehabilitation options overtime.  As municipalities, engineering firms and general contractors get involved with EIPI Technology, their conclusions will likely be the same as RESINATING’sEIPI Technology and RESINATING Fiberglass Expansion Liners will drive dramatic change in the way manholes, pipes and other structures are kept in good repair.

Compared to Resinating LLC’s EIPI Technology…
…everything else is a temporary fix!

EIPI Technology Basics

Before getting into the specific comparisons of EIPI Technology to the other options, let’s briefly review what Expand-in-Place Integration Technology and Resinating Fiberglass Expansion Liner are all about.

The Resinating Fiberglass Expansion Liner is fundamental to EIPI Technology. Its strength comes from the way it’s made…by winding continuous strands of E-Class fiberglass around a mandril, shooting chop between the layers, without adding any fillers.  It can be made to fit most shapes – cylindrical, conical, oval, domed and rectangular, etc. Each custom manufactured Resinating Liner is solid fiberglass.

Resinating Fiberglass Expansion Liners can be fabricated in diameters up to 192” and lengths of up to 18’ with thicknesses typically ranging from ¼” to ½” for a project, but can be thicker if needed.

The Resinating Liner is then cut axially enabling it to be compressed to a smaller size so that it can easily be inserted into a pipe or into a manhole through the manhole opening.  For example, a 54” diameter Resinating Liner was inserted into a manhole with an opening that was 20” wide.

After coating the existing walls of the pipe or manhole with Resinating’s Proprietary Bonding Agent, the compressed Resinating Liner is then moved into position, “expanded-in-place” and pressed firmly against the existing wall, forming a single, integrated structure, the bonding agent securing it for decades to come.  The seams and joints are then glassed, creating the tight bond associated with EIPI that is both 100% waterproof and incredibly strong…they were stronger than the existing walls were when they were new.

Here, a Resinating Installer is putting the finishing touches on a seam that was glassed over in a 20’ deep manhole.  You can see the new fiberglass floor and fiberglass trough at the bottom of the manhole.  It’s almost ready to close up with a new corbel.  A new corbel is not normally required but in this case installing one was the right thing to do.

With the Resinating Liner bonded to the walls of the existing manhole and the new corbel fiberglassed to the Resinating Liner, this manhole, like all other manholes and pipes that are rehabilitated using EIPI Technology, will provide great service for 100 years or more as it remains leakproof and stronger that when it was new.

More specific information about Resinating Fiberglass Expansion Liners and the other Resinating products associated with its EIPI Technology can be found in the Products Tab as well as on the Specifications and Tech Data Tab of this website.  In fact all of the other tabs, in particular the Home Tab, the Installation Examples Tab and the In The Media Tab, contain some very interesting additional information.

How does Resinating’s EIPI Technology compare to Trench & Replace?

Trench & Replace is certainly the most expensive way to “rehabilitate” a pipe or manhole.  ALL Trench & Replace options have a much higher upfront cost than using EIPI Technology to rehabilitate a pipe or a manhole.  ALL Trench & Replace options also have a much higher total cost over their lifetime.

  • The upfront financial costs of digging a trench, removing the existing pipe or manhole, hauling away hazardous waste, installing a new pipe or manhole and restoring the landscaping or repaving the roadway are eliminated when EIPI Technology and Resinating Fiberglass Expansion Liners are used to rehabilitate instead of replacing a failing structure.
  • The upfront social costs of congestion, disruption, blocked driveways and the release of environmentally unsafe gases and the presence of hazardous waste in the construction area are also eliminated when EIPI is used.
  • The longer-term costs of rehabilitating the structure again to deal with the I&I as it returns as the new pipe or manhole ages, adds a new round of financial and social costs to an already adverse situation.

Resinating’s EIPI Technology can rehabilitate all types of pipe and manholes…RCP, FRP, VCP, Brick, Cast Iron, etc, avoiding the need to do an expensive Trench & Replace project with all its costs.

Trench & Replace should only be considered in two specific situations:

  • SITUATION #1: If the collapsed or damaged pipe needs to be replaced anyway to increase the capacity of the pipe…but bear in mind that the very low coefficient of friction associated with Resinating Liners can also increase flow capacity somewhat.

Here’s an example:

Why do Trench & Replace just because of a collapse?  In many cases, one can simply Resinate it.  At the very least, it is rare for a pipe to be so collapsed that the entire pipe needs to be replaced. EIPI Technology and Resinating Fiberglass Expansion Liners can be used to rehabilitate those sections of a failing pipe where it isn’t totally collapsed beyond repair, saving substantial time and money.

In many cases, Resinating Fiberglass Expansion Liners and EIPI Technology can eliminate the need to Trench & Replace any “collapsed” sections…short “collapsed” sections can be used as insertion points for Resinating Liners. In the worst cases, a lot of EIPI Technology can be used with a little Trench & Replace to save a lot of money.  Let Resinating LLC evaluate any “collapse” situation before a decision is made to spend significant extra money doing an unnecessary Trench & Replace.

  • SITUATION #2: If the existing pipe is so totally collapsed that a RESINATING Fiberglass Expansion Liner cannot be inserted to rehabilitate the pipe or manhole. For perspective, however, if about 180 degrees or more of the pipe remains, the EIPI process can clean the collapse out and insert RESINATING Liners, bonding them to the existing walls, pouring concrete over the exposed part of the RESINATING Liner to finish it off.

Things to consider when considering Trenching & Replacing with RCP:

  • By using EIPI Technology to rehabilitate a pipe or manhole, instead of doing a T&R, one avoids the likely infiltration risk that will occur long before the end of the useful life of a Resinating Liner.  I&I issues down the road won’t exist when EIPI Technology is used. The cracks and resulting I&I that occur in RCP as it ages because of the loading that RCP must bear and the corrosive environment in which it exists are completely avoided with EIPI.
  • Resinating Fiberglass Expansion Liners have a very low coefficient of friction, likely increasing the flow capacity of a rehabilitated EIPI pipe vs the flow capacity of comparably sized RCP.
  • If one uses T&R with RCP, the additional cost to line the new RCP as it ages only worsens the already adverse financial picture associated with Trenching & Replacing. Rehabilitating the existing pipe using EIPI Technology is the most cost-effective solution by far, both on Day 1 and for the long term.
  • Utilizing Resinating Liners, bonded to existing pipes, not only renders them leakproof, it provides significant incremental structural integrity to those pipes. Pipes and manholes that are rehabilitated with EIPI Technology are stronger than when they were new. See the Technical Data Page on the Specifications and Tech Data Tab for ASTM test results relating to the strength of Resinating Fiberglass Expansion Liners vs. both RCP and FRP.
  • Also, Resinating Liners are not affected by any chemical or biological agents present in a waste water or storm water system. As a result, they are leakproof and maintain their structural strength for the very long term.
  • Resinating Liners installed using EIPI Technology carry a 20-year repair or replace warranty and have a likely useful life of 100 years, potentially longer. Why “potentially longer?”  Because Resinating Liners are solid, indestructible fiberglass. Why would they ever fail? We don’t know. Review the 20-Year Warranty on the Warranty Tab.

Things to consider when considering Trenching & Replacing with FRP:

  • When one is thinking about Trenching & Replacing with an FRP pipe such as Hobas, which is made with fillers, Resinating Liners installed using EIPI Technology will have a much longer useful life than this type of Trench & Replace option. Resinating Liners are solid fiberglass with no fillers added.  Solid fiberglass is virtually indestructible.
  • FRP may even have a much shorter useful life than the 20-year Warranty period associated with Resinating Liners given their strength, durability and leakproof qualities.  Publicly available information makes the point about the strength issues associated with FRP very clearly.  See the Technical Data Page on the Specifications and Tech Data Tab for ASTM test results on the strength of Resinating Liners vs FRP.
  • If one uses FRP in a Trench & Replace project, one will likely have to rehabilitate that FRP with a Resinating Fiberglass Expansion Liner some years after its installation, most likely due to deflection and cracking under load, thereby generating substantial infiltration. This only further inflates the cost of Trench & Replace with FRP as in the case with RCP vs rehabilitating a pipe with Resinating’s EIPI Technology.

EIPI Technology and Resinating Fiberglass Expansion Liners should always be the Day 1 choice for rehabilitating a pipe or manhole, not Trench & ReplaceResinating Fiberglass Expansion Liners are simply a superior solution when compared to any Trench & Replace option.

Resinating LLC’s EIPI Technology…THE BETTER CHOICE

…a much better choice than Trench & Replace

How does Reinating’s EIPI Technology compare to CIPP?

The CIPP process has been around a long time and has garnered many followers.  The belief that CIPP was the best solution for rehabilitating pipes was probably correct in many cases…until now. 

NOW, a new solution, a far better solution, is on the scene, Resinating LLC’s Expand-in-Place Integration Technology.  How much better?  A pipe (or manhole) rehabilitated with Resinating’s EIPI Technology is warrantied to be leakproof for 20 years.  Compare that to the performance of CIPP as documented below.

Review Electro Scan’s April 16, 2020 Press Release.  The results of their work in 2019 can be summarized as follows:

  • Having scanned over 110,000 LF of CIPP liners in 2019, using its patented low voltage conductivity technology, Electro Scan found over 14,000 leaks…that’s one leak every 7.85’.
  • Over 80% of CIPP liners inspected had measurable defects contributing to unwanted inflow and infiltration (I&I).
  • 44% of the leaks in pipes lined with CIPP exceeded 20 GPM.

The related Electro Scan inspection data from the March 11, 2020 Trenchless Technology Webinar sponsored by Electro Scan is in the table below on the left.  That table shows the severity of leaks PER CIPP DEFECT.  The resulting percentages of leaks within each range in the Electro Scan Table are shown on the right.

When the mid-point of each range (25 GPM for the highest range) is multiplied by the percentage of leaks within each range as shown in the table on the right and then summed, one finds that the AVERAGE LEAK/DEFECT is 11.07 GPM after a pipe is lined with CIPP

What does that mean?  If one takes the fact that the leaks on average are 8’ apart as Electro Scans data shows, that means that when one mile of average pipe is lined with an average level of CIPP defects, there is 7,260 GPM of continuing I&I during an infiltration period or 10 Mil GPD of infiltration in a 24-hour day.  If the average cost of treating wastewater at a WWTP is $500/MG, then the cost for a day of that infiltration would be about $5,000.  And as the Electro Scan webinar pointed out, that I&I flow rate increases with time.

Also, note that the Electro Scan data is typically the result of inspecting smaller diameter CIPP lined pipes.  It is reasonable to assume that as the diameter of the pipe increases, the number of defects and the resulting infiltration flow will increase in line with the increase in the surface area of the CIPP liner.  Ongoing infiltration after a pipe is lined with CIPP can be very costly.

And, of course, this continuing infiltration over time leads to the CIPP liner being increasing damaged and separating from the substrate.  Testimony to this is that there are products that are specifically designed and marketed to remove failed CIPP liners.  Resinating Fiberglass Expansion Liners installed using EIPI Technology do not fail.  They are warrantied not to fail for 20 years and likely won’t fail for more than 100 years if ever.  That’s why we refer to EIPI Technology as “the ‘forever’ rehabilitation solution.”

How do these CIPP results compare to the results one will get when achieve when using Resinating’s EIPI Technology?  With EIPI Technology, Resinating Fiberglass Expansion Liners are bonded to the existing walls of the pipe (or manhole) using Resinating’s Proprietary Bonding Agent to rehabilitate the pipe or manhole?

  • Resinating’s EIPI Technology has a 20-year Warranty against leakage, such that if any leakage occurs that materially and substantially adversely affects the performance of a pipe or manhole, Resinating LLC will repair or replace its Liner. You can review the 20-Year Warranty on the Warranty Tab. You will note that the Warranty covers both materials and workmanship.
  • Resinating’s EIPI Technology has a likely useful life of 100 years or more.  This long useful is life is due to the fact that:
    • Resinating Fiberglass Expansion Liners are solid, indestructible fiberglass…there are no fillers in Resinating Fiberglass.
    • Resinating’s Fiberglass Expansion Liners provide new strength to existing pipes and manholes so they can carry increased loads…the structural integrity of pipes and manholes rehabilitated with EIPI Technology is far greater than when they were new.
    • RESINATING Fiberglass Expansion Liners are impervious to any chemical or biological agents found in waste water, storm water or fresh water systems.

From a cost perspective, there is no question that over the short- to medium-term, and probably on Day 1 in many, many cases, the cost of using Resinating’s EIPI Technology to rehabilitate a pipe is far less than the cost of CIPP, particularly when one considers the substantial additional cost of treating the ongoing infiltration and the cost of rehabilitating the pipe again, not to far down the road, this time presumably with Resinating’s EIPI Technology. Money spent on lining a pipe with CIPP is essentially wasted money.

And one must not ignore the structural integrity provided by EIPI Ptechnology and Resinating Liners.  CIPP does not provide any measureable structural integrity, especially as the CIPP delaminates!

See the Technical Data Page on the Specifications and Tech Data Tab for ASTM C497 test results on the strength and structural integrity delivered by Resinating Liners vs RCP and FRP.  No C497 tests have been conducted ever on CIPP, at least not that we are aware of.  Pipes rehabilitated with Resinating’s EIPI Techniology create an integrated structure that is stronger than when the failing pipes were new.

In addition to the cost comparison developed above, additional factors comparing the use of EIPI Technology vs CIPP are in the table below.  These comparisons reflect Resinating LLC’s assessment of using Resinating’s EIPI Technology vs. CIPP and are believed to be appropriate characterizations of EIPI vs CIPP.  The links in the table provide very important information that should be reviewed.

Specification/Guideline Resinating EIPI Technology CIPP
Manufacturing Method IN FACTORY:  A Resinating Fiberglass Expansion Liner is manufactured using continuous fiberglass strands coated with a specific resin selected for the specific job.  The fiberglass strands are wound on a mandril to create a liner section with the proper diameter and thickness appropriate to the pipe being rehabilitated. The Resinating Liner section is fully cured prior to shipment. ON-SITE: Fiber and resin are encased in a flexible hose and cured in place in a pipe by a chemical reaction triggered by the injection of steam, hot water or UV as the catalyst.
Installation Method TRENCHLESS: The Resinating Liner section is cut axially, compressed to a smaller diameter so it can be easily inserted into the existing pipe through a manhole or via a small (approximately 20’ long) insertion point cut in the middle of the existing pipe.  From this insertion point, something approaching 1,000’ of pipe can be rehabilitated in both directions on a straight run. TRENCHLESS: The resin soaked felt CIPP is inserted inside the existing pipe, running between two manholes at which point a catalyst is introduced to cause the resin to cure.
Bonding Method The walls of the existing pipe are coated with Resinating’s Proprietary Bonding Agent prior to the compressed liner being Expanded-in-Place to bond it to the existing walls. This secures the Resinating Liner to the walls of the existing pipe after which the joints and seams are fiberglassed to create a watertight unit, structurally integrated with the existing walls. CIPP liners are not bonded to the existing pipe.
Installation Safety Issues None. When the catalyst is introduced to cure the resin, various carcinogens are released into the air.  See this MIT article. The article includes a link to a detailed 2017 Purdue University research report worth reviewing. Also check out this Scientific American article and be sure to read the September 2020 State of Florida CIPP Research Report.
Structural Strength Resinating Liners combined with Resinating’s Proprietary Bonding Agent give the failing RCP 50% more strength than the new RCP…a 100% increase vs. FRP. See the ASTM C497 & ASTM D790 test results available on this website on the Tech Data Link of the Specifications and Tech Data Tab. CIPP Corporation says “CIPP is designed to support the hydraulic loads due to groundwater, since the soil and surcharge loads can be supported by the original pipe.  That is UNLESS the original pipe is not structurally sound.
Effect on Pipe Capacity The low coefficient of friction and thinness of the Resinating Liner, typically ½” or less, could generate a moderate positive effect on the flow capacity of a pipe. The typically thicker nature of CIPP installations and their relatively coarse surface, particularly as they age, can degrade the flow capacity of the pipe.
Warranty Period 20 Years. Typical construction warranty for CIPP is 1 year.
Useful Life 100 years or more.

Resinating Fiberglass Expansion Liners are solid fiberglass that is essentially indestructible.  It is completely impervious to the chemical or biological agents in municipal wastewater, storm water and many industrial environments.

Unknown, but apparently not long. Based on Electro Scan data, available videos, and the fact that there are products being marketed that are specifically designed to remove failed CIPP Liners without damaging the host pipe, it is clear that CIPP doesn’t come close to matching the 100+ year useful life of Resinating Liners.  Leaks are there from the beginning and increase with time and are worsened by jetting clogs, ultimately leading to delamination.

CIPP Failure 1

CIPP Failure 2

Cost Often less expensive than CIPP on Day 1, the life time cost of Resinating’s EIPI Technology is substantially less than that of CIPP given the likely limitations of CIPP’s useful life (years, not decades), the likely need to install EIPI Technology soon after the installation of CIPP and the costs of treating any ongoing infiltration starting on Day 1 and increasing as the CIPP ages. <== No sense repeating things.

Clearly, EIPI Technology and Resinating Liners should be the Day 1 choice for rehabilitating a pipe, not CIPP.  Resinating Fiberglass Expansion Liners and Resinating’s EIPI Technology simply provide a far superior solution to that which CIPP can provide when pipes in a wastewater or storm water system need to be rehabilitated.

Resinating LLC’s EIPI Technology…THE BETTER CHOICE

…a much better choice than CIPP

How Does Resinating’s EIPI Technology Compare to SIPP?

Resinating’s EIPI Technology integrates Resinating Fiberglass Expansion Liners with the existing walls of the manhole to form a single, solid, structural unit that is both leakproof and stronger by far than the existing unit was when it was new.  SIPP cannot do this.

Due to the fact that Resinating Fiberglass Expansion Liners have a useful life in excess of 100 years, whereas the useful life of an SIPP installation is much less as documented in our press release on our TRA Experience, it is clear that the cost of SIPP, even if it happens to be less on Day 1, is far more costly than using EIPI Technology over the short term, let alone the longer term.

While we do not have specific “Electro Scan like data” on I&I in an SIPP lined manhole, given that for SIPP to be effective, it must be applied to a clean, dry surface…not a common situation in sewer system, it probably isn’t a good story.

As with CIPP, one must not ignore the structural integrity that EIPI Technology provides.  SIPP does not provide anywhere near the structural integrity, if any, that EIPI Technology offers. See the Technical Data Page on the Specifications and Tech Data Tab for ASTM test results of the strength of Resinating Liners vs RCP and FRP.  Manholes lined with Resinating Liners using EIPI Technology create a structure that is stronger than when the failed manholes were when they were new.

The factors comparing the use of Resinating’s EIPI Technology to SIPP are summarized in the table below. These comparisons reflect Resinating LLC’s assessment of using Resinating’s EIPI Technology vs. SIPP and are believed to be appropriate characterizations of EIPI vs SIPP.  The links in the table provide very important information that should be reviewed.

Specification/Guideline Resinating EIPI Technology SIPP
Manufacturing Method IN FACTORY:  A Resinating Fiberglass Expansion Liner is manufactured using continuous fiberglass strands coated with a specific resin selected for the specific job.  The fiberglass strands are wound on a mandril to create a liner section with the proper diameter and thickness appropriate to the pipe being rehabilitated. The Resinating Liner section is fully cured prior to shipment. ON-SITE: A coating is sprayed in place in the manhole.
Installation Method

TRENCHLESS: After fiberglassing a new floor and trough into place in the manhole, the Resinating Liner section is cut axially, compressed to a smaller diameter and inserted into the existing manhole through its opening.

Review the slide show on the St. Paul, Kansas manhole installation in the Installation Examples Tab.  For added perspective, we rehabilitated the TRA manhole, 54” in diameter, inserting the Resinating Liner through its 20” manhole opening.

TRENCHLESS: A sprayer is lowered into the manhole to spray the existing walls. The walls must be clean and quite dry during the spraying for the SIPP be effective. The floors and trough in manholes are not typically rehabilitated when SIPP is used.
Bonding Method The wall and floor of the existing manhole are coated with Resinating’s Proprietary Bonding Agent prior to the new fiberglass floor and new fiberglass trough being installed. Then the manhole walls are coated with Resinating’s Proprietary Bonding Agent after which the compressed Resinating Liner is put in place and expanded. The Resinating Liner and the floor and the trough are then glassed together as is the seam and any joints, resulting in a manhole that is 100% leakproof and incredibly strong. Unlike the EIPI Technology process, SIPP liners are not bonded to the existing manhole walls resulting in no added strength and greater likelihood of leakage.
Installation Safety Issues None. Unknown.
Structural Strength Resinating Liners combined with Resinating’s Proprietary Bonding Agent give the failing RCP 50% more strength than the new RCP…a 100% increase vs. FRP. Resinating’s EIPI Technology is truly incredible. See ASTM D497 & ASTM D790 test results available at the Tech Data Page of the Specifications and Tech Data Tab. Likewise, EIPI Technology greatly strengthens any other material that a manhole was originally constructed with – brick, whatever. There is no apparent incremental structural strength associated with an SIPP liner.
Warranty Period 20 Years. Unknown. Perhaps 1 year.
Likely Useful Life In excess of 100 years.  Resinating Fiberglass Expansion Liners are solid fiberglass, essentially indestructible and completely impervious to the chemical or biological agents in wastewater. Based on the experience that the Trinity River Authority in Texas has had with SIPP, the likely useful life of an SIPP lining is in the range of 3 to 4 years or so. Details on the TRA Experience can be found in the Press Release Tab of this website.
Cost The lifetime cost of using Resinating’s EIPI Technology to rehabilitate a manhole is substantially less than using SIPP to do that given SIPP’s limited useful life, and the need to rehabilitate the manhole again, presumably by using EIPI Technology, at some later point and the treatment costs for any infiltration that occurs as the SIPP ages. <== No sense repeating things.

Clearly, Resinating’s EIPI Technology and Resinating Fiberglass Expansion Liners should be the Day 1 choice for rehabilitating a manhole, not SIPPResinating Fiberglass Expansion Liners and Resinating’s EIPI Technology are simply a superior solution compared to SIPP when manholes need to be rehabilitated.

In Summary

When one considers all the advantages of using Resinating’s EIPI Technology developed in this, The Better Choice page, it is difficult to conceive of a choice that would be superior to the choice of using Resinating’s EIPI Technology to rehabilitate one’s manholes and connecting pipes.

  • The fact that a Resinating Liner is 100% leakproof and impervious to corrosion from any chemical or biological agents found in waste water, storm water, fresh water and many other industrial and commercial liquids,
  • The incredible strength and structural integrity of a Resinating Liner, installed using EIPI Technology,
  • The indestructible nature of Resinating’s fiberglass,
  • The 20-year repair or replace warranty associated with Resinating Liners if they were to leak,
  • The useful life of Resinating Liners — 100 years or more,
  • The fact that EIPI Technology eliminates virtually all excavation, traffic congestion, hazardous waste removal, resurfacing and landscaping costs associated with Trench & Replace,
  • The lack of health risks like those associated with styrene and various VOC’s that are released during the installation of CIPP,
  • The rapid pace at which Resinating Liners can be installed – a typical manhole can be lined in a day as can several hundred feet of pipe on a straight run,
  • The savings associated with using Resinating Fiberglass Expansion Liners and Resinating’s EIPI Technology, both upfront and over the life of a rehabilitation project…

…these are the major factors that will propel Resinating’s EIPI Technology forward, displacing other rehabilitation methods.  Resinating’s EIPI Technology will drive dramatic change in the way manholes and pipes are kept in good repair.”
