Epoxy passes Chlorine testing. The Perma-Liner formulated epoxy was tested against Chlorine – and passed all testing. This is huge step for Perma-Liner and the ability to rehabilitate pool lines. Some of our Certified Installers work across the Country specifically repairing pool lines – as these are usually a no-dig situation. You can Perma-Line it within a matter of hours – Winter, Spring, Summer or Fall!
