Pre applied HDPE water proof membrane with granules adhering to concrete waterproof basement walls

OTAi HSA is a kind of high density polyethylene self-adhesive film waterproof membrane. It uses the high density thermoplastic polyethylene (HDPE) as waterproof base material and on one side of HDPE we cover a layer of compression sensitivity high macromolecule adhesive and a granular layer with unique formula as the isolation layer. Our HSA sheet material can be used on the flat concrete surface and compacted sandy subcrust. It is designed for underground engineering construction and it can bind the later cast concrete form a firm structure.

1.\tWhen casting concrete, the concrete mortar and material are combined to form a special macromolecular polymer to make curing reaction adhering so that coiled material structure is adhered together permanently. No water fleeing inside the structure, and increase the reliability of waterproof layer
2.\tIt has strong self-heating ability and can repair slight construction injury.
3.\tHigh strength of extension
4.\tStrong chemical resistance and strong resistance to acid and alkali
5.\tIntegration of self adhesion, water proof and protection, so that can reduce construction links
6.\tWet method construction, no need flat layer, low requirement for base, not affected by weather and base moisture, it has obvious advantage of constructions in rainy season.
7.\tWaterproof sheet material is not adhering on base, therefore it is not affected by settlement deformation.
