About

SikaProof-312 IN HDPE is a unique HDPE based self adhesive membrane comprising of a virgin HDPE layer, coated with a high bond strength adhesive, and covered with a release liner, for below ground waterproofing of reinforced concrete structures. It is loosely laid onto prepared substrates or formwork before fixing reinforcement and casting concrete. In pre applied applications the adhesive layer is activated when the concrete is poured on the surface and forms a permanent bond with the fresh concrete which will prevent the ingress of water around the structure. Reinforcement can be directly laid on top of the membrane and it does not require screed protection. For post applied applications it is directly bonded with the substrate by stripping off the release liner at the bottom and fixing on the PCC below before casting the raft slab.
