Protan FPO Proven can be applied without using any heat source thanks to its fully adhesive joints before concrete casting and reinforcement placement. It is easy to apply with the help of acrylic tapes and offers fast, safe and economical solutions. Protan FPO Proven Plus is a self-healing waterproofing membrane that has been chemically treated on one surface and laminated with a special felt. Protan FPO Proven Plus repairs itself as crystallized in the punctured area thanks to the chemical in its structure against the puncture and tearing that may occur during the application.
