  • The Benefits of Using Epoxy Resin Liner for Pipe Relining

    Plumberbondi Epoxy Pipe

    Both plumbers and contractors like to use pipe relining in most of their repairs since there is minimal property disruption, can be done quickly, and can enhance the health of the sewer pipes. The pipe relining method centres around the material called the resin liner. A lot of processes are involved to ensure that the resin liner can fit into the sewer system, positioned at the right points, and perfectly attached to the host pipe. There are different types of resins used for the liner such as fibreglass, polyester, vinyl ester, and epoxy. In this article, we’re going to concentrate with the benefits of using epoxy resin liner for pipe relining.

    Bonding strength is high

    What separates epoxy with the other types of liners is its bonding strength. Don’t get us wrong, the other resin types are still ductile and sturdy–and they’re even resistant to chemicals and corrosion, but the bonding strength and durability of epoxy is much greater. Because of the amazing toughness and stability of epoxy, a lot of contractors use it for their resin liners. The bonding strength dictates if the resin liner will deeply attach itself to the sewer lining, enhancing the structure of the pipeline. The higher the bonding strength, the more fortified the pipes become. The high bonding strength comes with a price since epoxy has the longest curing time among the basic resins.

    It has a low shrink rate

    Almost all resin types will eventually shrink as time passes, even epoxy. The shrink rate isn’t an issue if the resin liners have a low shrink rate. However, for liners like polyester and vinyl resin that have a high shrink rate, the owners of the pipes will have a bit of a problem since this will mean that the pipes will need a bit of maintenance. With regards to epoxy liners, you don’t have to worry too much about any maintenance because of its low shrink rate and can still have a tight hold on the pipes.

    Epoxy doesn’t produce foul odours and has no volatile organic compounds (VOC’s)

    Some issues with resin liners during relining is that it emits a chemical odour that can be pretty inconvenient for anyone in the dig site, especially if the work area doesn’t have any proper ventilation. Some types of resin liners produce chemical smells due to the compositions of the material. The main culprit for this is the styrene compound found in some lines. Fortunately, epoxy resins don’t have any styrene or other compounds that create odours. In addition, volatile organic compounds are also other drawbacks that are found in few resin liners available in the market, but again, epoxy resin doesn’t contain such materials.

    Greatly improves the wastewater flow

    Among the key features of epoxy resin is its ability to prevent root attacks and even lower the chances of leakage within the pipe lining. Apparently, it has an additional benefit which is the ability to improve the flow of wastewater in the sewer line. Epoxy is able to embellish the flow because of its polished surface.
