Characteristics and Applications of Geomembranes

News

Geomembrane is a waterproof and barrier material based on high polymer materials. It is mainly divided into low-density polyethylene (LDPE) geomembrane, high-density polyethylene (HDPE) geomembrane, and EVA geomembrane. The warp knitted composite geomembrane is different from general geomembranes. Its characteristic is that the intersection of longitude and latitude is not curved, and each is in a straight state. Tie the two firmly with braided thread, which can be evenly synchronized, withstand external forces, distribute stress, and when the applied external force tears the material, the yarn will gather along the initial crack, increasing the tear resistance. When warp knitted composite is used, the warp knitted thread is repeatedly threaded between the fiber layers of warp, weft, and geotextile to weave the three into one. Therefore, the warp knitted composite geomembrane has the characteristics of high tensile strength and low elongation, as well as the waterproof performance of the geomembrane. Therefore, warp knitted composite geomembrane is a type of anti-seepage material that has the functions of reinforcement, isolation, and protection. It is a high-level application of geosynthetic composite materials internationally today.

2. Waterproof board or geotextile membrane for landfill sites
3. Geomembranes or composite geomembranes for reservoirs and canals
4. Geomembrane or composite geomembrane for reclamation and dredging
5. South to North Water Diversion Project, River Management, Sewage Treatment, Dam Seepage Control, Canal Lining, Environmental Protection and Reclamation, and Highway and Railway Seepage Control
HDPE geomembrane is made of polymer raw materials (original raw materials) such as resin polyethylene, high wall polypropylene (polyester) fiber non-woven fabric, ultraviolet light barrier, anti-aging agent, etc., by one-step extrusion processing of automatic production line. The middle layer of HDPE geomembrane coiled material is a waterproof layer and anti-aging layer, and the upper and lower sides are reinforced bonding layers, which are firm, reliable, free of warping edges and hollowing, and double-layer waterproof, forming a complete waterproof system.

HDPE geomembrane is suitable for waterproofing projects in various buildings such as roofs, basements, tunnels, and aquaculture; Waterproofing for roof and underground engineering, water storage tanks, municipal engineering, bridges, subways, tunnels, dams, large sewage treatment plants and other projects in civil and industrial buildings is particularly suitable for projects with high durability, corrosion resistance requirements, and easy deformation.
