WIILOCK (E-LOCK) Concrete Insert HDPE Profile
Securing geomembrane liner to concrete structures can be carried out either by mechanical fastening (using stainless steel flat bar, neoprene sponge and anchor bolts) method OR by embedding WILLOCK into concrete and geomembrane liner is then welded onto the exposed surface of WILLOCK using extrusion welding method.
Wil-Key International produces WILLOCK in different shapes and custom length to suit the actual project requirement.
All WILLOCK are made from virgin HDPE resin with 2 to 3% carbon black content. WILLOCK are made from the grade of resin normally used by major geomembrane manufacturers for make HDPE geomembrane liner.
The advantages of using WILLOCK against mechanical fastening are cheaper in cost, easier to install and more secured.
