Effective One-Cloth-One-Membrane Compound Geomembrane For Anti-Seepage And Reinforcement
Product Introduction
The geomembrane is a geosynthetic material made by calendering and hot-melting a layer of geotextile (such as long and short yarn needle-punched geotextile, woven geotextile, plastic woven fabric or bentonite waterproof blanket) and a layer of polymer material (such as HDPE film, LDPE film or EVA film). This material combines the flexibility, corrosion resistance, puncture resistance and other properties of geotextile with the anti-seepage performance of geomembrane.
Product Properties
The one-cloth-one-membrane composite geomembrane has the following characteristics:Good flexibility: It can adapt to different terrains and uneven foundation settlement. High physical and mechanical performance indicators such as tensile strength, tear resistance, and bursting resistance: It ensures the strength and durability of the material. Sealing (anti-seepage) function: It effectively prevents water from penetrating. Wide applicability: It can be used for anti-seepage projects in many fields such as water conservancy projects, road traffic, and environmental protection.
Product Application
It is mainly used in civil engineering projects that require anti-seepage, isolation, reinforcement and anti-cracking reinforcement, such as anti-seepage treatment of dams and drainage ditches, and anti-pollution treatment of material yards, etc.
