Hot melt monolithic waterproofing system.
PermaTEC LI provides a waterproof membrane for use on inverted, green and flat roofs, including completely flat protected roofs.
IKO Permatec LI Hot Melt Monolithic Waterproofing Systems comprise IKO Permatec LI and IKO Permatec LI Anti-Root hot melt waterproofing compounds.
They are specially formulated combinations of refined bitumen, synthetic rubbers, fillers and other additives, which are hot-applied in conjunction with carefully selected reinforcement/ detailing fabrics and protection layers.
IKO Permatec LI offers an environmentally conscious option with a third-party verified GWP reduction in embodied carbon of up to 50%.
Installed by a nationwide network of registered installers, IKO Permatec LI provide a fully bonded, tough, flexible, waterproof membrane for use on inverted, green, bio-diverse, blue and flat roofs, including zero-fall protected roofs.
IKO Permatec LI is also suitable for use as a damp-proof membrane in solid concrete floors or as the waterproofing layer in a typical sandwich membrane used for above or below ground waterproofing in concrete, brick or blockwork structures.
