Lining Materials - Epoxy Resin


Epoxy resins are supplied as two-part solvent free systems consisting of resin or base material and hardener or activator. When properly mixed they will give a rapid cure, high-build, potable water certified material. The cured material is inert and achieves corrosion protection by providing an impermeable barrier, effectively separating the water from the pipe material, thereby stopping further corrosion.

The finished coating is smooth and hard with excellent water resistance and hydraulic profile.

The lining will not impair the quality of potable water, nor will it affect the pH. The thin, smooth coating enhances flow capacity of previously corroded mains enabling pressure reduction to be readily achieved.

The epoxy resin coatings are applied with the use of in-situ lining rigs equipped with heated materials storage tanks and umbilical hoses and application spray heads.

In the United Kingdom, there has been a complete transition from cement mortar to the exclusive use of epoxy resin/polymeric materials. The main reason for this change was the result of the development of water quality issues associated with cement mortar lining.
