Why should the reservoir be laid with geomembrane? Prevent leakage: As an important facility for water storage and deployment, the reservoir must have good anti-seepage performance. Geomembrane has good anti-permeability, which can effectively prevent the penetration and loss of water and solute. By laying geomembrane on the bottom and side walls of the reservoir, the […]

Why is geomembrane used in tunnel engineering? 1. Waterproof protection: geomembrane can play a waterproof role, effectively preventing groundwater, surface water and rainwater from penetrating into the tunnel structure. Tunnel engineering often requires a lot of excavation and groundwater control. Geomembrane can provide a reliable waterproof barrier to avoid water erosion and damage to the
What is the stiffness of geomembrane？ The stiffness of geomembranes is usually described by stiffness index or deflection. Stiffness index is a quantitative parameter of bending stiffness of a material under certain conditions, usually expressed in K value, and the unit is m⁴/N. Deflection refers to the degree to which a material bends when an

HDPE geomembrane is mainly used in the following aspects: Anti-infiltration: As a waterproof layer, HDPE geomembrane can effectively prevent the infiltration of water, liquid or gas. It can be used in various civil engineering projects, such as water conservancy projects, sewage treatment plants, landfills, etc., to isolate groundwater and surface soil. Isolation protection: Geomembranes can
Manufacturing and testing of HDPE geomembrane products should be the latest version and revised in accordance with the following standards or equivalent and compared to a higher standard, if not in China, please examine according to the origin of the inspection standard. Tensile test of geomembrane Sample Preparation: Cut representative specimens, usually rectangular in shape,

What are the raw materials of geomembrane？ The main raw material of geomembrane is high-density polyethylene (HDPE). HDPE is a thermoplastic polymer material formed by polymerization of ethylene monomers, with the following characteristics: High density: HDPE has a high molecular weight and density, which gives the geomembrane good mechanical strength and tensile resistance, and can
What are the types of surface types of geomembranes? Geomembrane is an important material used in civil engineering and environmental protection, mainly for anti-seepage, isolation, and reinforcement. The surface of geomembranes usually has the following forms: Smooth surface: The surface of some geomembranes is smooth, which is to reduce the friction force of water flow

Anti-seepage principle of geomembrane Physical isolation: Geomembranes have high sealing and anti-seepage capabilities, which can form a physical barrier that effectively prevents moisture, gas or other liquids from penetrating through soil or rock layers and entering the area below. Geomembranes have low permeability through their own material properties, such as high-density polyethylene (HDPE), which reduces
