Polymer (non-bitumen) self-adhesive Waterproofing coil membrane is made of various polymer sheets as base materials covered with one self-adhesive layer and with the isolating membrane or sand layer as the isolating layer. Moreover, the polymer sheet includes various plastics such as HDPE, TPO, PVC, EVA, ECB, and elastomer such as EPDM.
The polymer self-adhesive membrane (non-bitumen-based) waterproof sheet is constructed in pre-applied full bonding method, and it can achieve high-strength and permanent bonding with the poured concrete through chemical bonding and physical crosslinking, which can prevent water channeling, is unaffected by the displacement of base course, and can maintain high peel strength even if immersing in water for a long time. The construction is convenient, and after simple treatment, the framework of steel reinforcement can be placed and poured.
Construction technology in pre-applied full bonding method is adopted, and the coiled material and the structural layer are directly bonded to form “skin-type” waterproof effect, thus completely eradicating water channeling;
It's required to fabricate the protective layer for the sand coiled material, and after the waterproof layer passes the acceptance, it's allowed to directly assemble the reinforcement and pour the structural concrete;
The construction is convenient, the requirement for base course is low, and the construction period is short;
Excellent resistance puncture and weather, and long lifetime;
With good bonding effect, the product can maintain high peel strength even if immersing in water environment for a long time.
