Product Overview
这里是标题一h1占位文字
This product is a self-adhesive waterproofing membrane made of polymer sheet (PE/EVA/TPO/EPDM, etc.) as the surface material, polymer adhesive material as the self-adhesive layer, silicon coated isolation film, protective sand or protective coating as the isolation layer, after a special composite process.
Product Features
Construction Method
Pre-paving method
The coil is laid empty on the grass-roots level, and the material is lap-treated and tied directly to the reinforcement and poured concrete. In the concrete solidification, and coil 100% solid bonding, and the formation of a dense waterproof layer.
