Waterproof Materials Good Price HDPE Self Adhesive Waterproof Membrane for Bridge Waterproofing

Product Description

OTAi pre-applied HDPE membrane is a multilayer compound waterproof material with excellent performance. It includes one layer of high density PE film, one layer pressure sensitive polymer adhesive and one insulation layer. It is widely used on flat concrete surface or compacted sandy layer as well as waterproof layer of vertical surface of temporary and adjacent structures to form continuous and permanent combination.

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 layer.

2. 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 alkali.

5. Integration of self adhesion, waterproof and protection, so that can reduce construction links.

6. 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.
