Seamless HDPE Smooth Geomembrane For Effective Seepage Control
Product Introduction
Smooth geomembrane, also known as smooth geomembrane, is a kind of waterproof barrier geosynthetic material with high polymer as the basic raw material. It is made of high quality primary high density polyethylene (HDPE) as impermeable substrate, adding carbon black, antioxidant, anti-aging agent, ultraviolet absorber and color masterbatch through special formula, and using three-layer co-extrusion blow molding technology. This material has very low permeability, excellent chemical resistance and UV resistance properties, and cost-effective, is the first choice of civil engineering seepage prevention materials, widely used in many fields.
Product Properties
1. Environmental protection: does not contain harmful substances, do not pollute the environment.
2. Reusability: Only the surface layer can be replaced, saving resources.
3. Wide range of application: suitable for basement, pool and other types of waterproof projects.
4. Uv resistance: Protects the material from UV damage.
5. Good stability: it is not easy to deform or break under physical action.
Product Application
1. Water conservancy: can be used for seepage, drainage, protection and so on.
2. Environmental protection: suitable for landfills, sewage treatment plants, etc.
3. Municipal engineering: can be used for waterproofing and protection of underground facilities.
4. Aquaculture: Used for seepage prevention of fish ponds, shrimp ponds, etc.
5. Sewage treatment: applied in tailings seepage prevention and landfill.
6. Landscape: provides beauty while ensuring water resistance.
7. Hydraulic engineering: plays a role in the seepage prevention of DAMS and reservoirs.
