EVA Geomembrane/EVA Waterproof Board
Product Information
EVA waterproof board is a kind of polymer material which is made of ethylene and vinyl acetate copolymer modified polyethylene waterproof board and some additives. Compared with the waterproof roll material heated by geotextile, it has good waterproof performance, but also has tensile resistance, tear resistance, and is easy to weld. Needle-punched geotextile can also play a very good play in drainage guide layer and buffer protective layer. Moreover, it is very convenient to construct by inserting suspenders between textile and membrane.
Product Features
1. EVA geomembrane is acid and alkali resistant chemicals. It has good dimensional stability and good adhesion, and is convenient for construction.
2.EVA geomembrane has better isolation and puncture resistance.
3. EVA geomembrane can be impervious and isolated without chemical pollution.
4. EVA geomembrane has excellent flexibility, anti permeability, elongation and wear resistance.
Product Uses
Municipal garbage landfill, coal ash dam treatment, road, railway, drainage works, water conservancy, tunnels, dikes, dams and gates impervious, reservoir impervious, water conveyance, transfusion channels, solid waste piled impervious, roof impervious, building basement, underground garage moisture-proof, land reclamation, wharf project, golf course, port construction Wait.
