What Is A Resin Liner, And Why Do I Need It?


If your pipes have structural problems, pipe rehabilitation can be the right solution. While plumbing problems can be messy, using resin liners makes for quick – and satisfying – work. They are essential for performing trenchless services. Here’s what you can expect and why you may need one!

What Is A Resin Liner?


Once we have installed the liners, we soak a pipe-lining resin to ensure the liner adheres to the host pipe during the curing process. Once the curing is complete, the resin liner will be as hard and durable as a new pipe!


There are three types of resin liners: Polyester, Vinyl, and Epoxy.



Polyester Resin: The most affordable type of resin, polyester is the material of choice for sewer lines, stormwater drainage systems, and other municipal plumbing projects. It meets many municipal codes, and it can be mixed to alter the cure time anywhere between a few minutes to several weeks!
Vinyl Resin: A hybrid of epoxy and polyester, vinyl is often used where extreme corrosion resistance is needed. Since it has polyester properties, it also has the same drawbacks – noxious odours and volatile organic compounds (VOCs). Vinyl resin is also prone to shrinking as it cures.
Epoxy Resin: Epoxy resin does not contain any dangerous fumes or VOCs, and it does not shrink as it cures. These properties make epoxy resin the go-to choice for lining indoor commercial, industrial and residential plumbing pipes. We must mix it on-site, as the epoxy resin has a short curing time.

As mentioned, of the three types, epoxy resin is what we would use for residential and most commercial projects. Once the two-part epoxy is mixed, a chemical reaction causes the material to heat up and the resin to cure. We pour it into the liner, insert the liner into the lateral pipe for curing, then inflate an inner bladder to form the material to the pipe.


Why Do I Need A Resin Liner?


Relining a pipe with a resin liner is how we rehabilitate any drain, waste, and vent lines that may have been damaged over time. Rather than dig out the pipe – which can be costly and damaging – putting in a resin liner can make the line like new, allowing an existing damaged pipe to once again provide problem-free drainage.

It starts with a video inspection to determine the cause of your problem. The causes are most often cracks, breaks, deterioration, and leaks that come from age and use, but they can often be tree roots affecting main sewer lines. Once we see the issue for ourselves, we’ll know whether a resin liner is an appropriate measure.

One of the key advantages of a resin liner is how quickly it solves the problem. You avoid having a company digging out the lines through your concrete and landscaping, and because the epoxy resin cures quickly, the pipes can be returned to service quickly, too!
