WATERPROOFING MEMBRANE MANUFACTURER
What are the characteristics of Pre applied HDPE waterproof membrane
Pre-applied HDPE waterproof membrane belongs to GB/T 23457-2017 Pre-applied waterproofing membrane plastic membrane, it takes HDPE sheet as the main material, plus self-adhesive, surface anti-(reducing) adhesion protective layer (except the membrane Lap area) and isolation material (when necessary), and it is bonded with post-cast concrete to prevent water from sticking to the bonding surface.
Pre-applied HDPE waterproof membrane is suitable for plastic, asphalt, rubber as the main material, with self-adhesive on one side, and the adhesive surface is treated with non-stick or viscosity-reducing material, and is bonded with post-cast concrete.
Pre-applied HDPE waterproof membrane material is hard and has good puncture resistance. It is not easy for sharp objects to pierce the waterproof layer. Due to the hard material, it is inconvenient to construct the yin and yang corners. Generally, it is mainly used for underground waterproofing works of civil and industrial buildings.
