Product Description
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.

Characteristics
1.When casting concrete, the concrete mortar and material are combined to form a special macro molecular 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 layer2.It has strong self-healing ability and can repair slight construction injury.3.High strength of elongation, strong breaking tensile strength and good anti-perforation performance .4..With strong chemical resistance to acid and alkali5.Integration of self adhesion, waterproof and protection, so that can reduce construction links6.Wet method construction, no need flat layer, low requirement for the base, not affected by weather and base moisture, it has obvious advantage of constructions in rainy season.7.The floor board of the building should be constructed with a pre-applied anti-sticking method. This method no need protective layer.8. one layer can reach level one waterproofing security requirements
