700 grams of two cloths and one film composite geomembrane"It is a composite geotechnical material, which is composed of two layers of geotextile and a layer of geomembrane through a special process. The specific analysis is as follows:
700 grams": This value usually refers to the total weight of the composite geomembrane of 700 grams per square meter. Weight is an important indicator to measure the density of the material per unit area of geotechnical materials, which directly affects the mechanical properties, thickness and difficulty of construction.
Two cloths and one film"This structural design refers to a layer of geomembrane (such as HDPE film or PVC film, etc.) sandwiched in the middle, and a layer of geotextile (generally staple fiber needle-punched non-woven fabric or filament woven fabric) is attached on both sides. Among them, the geomembrane plays the main role in preventing seepage, while the geotextile on both sides enhances the tensile strength, puncture resistance and contact friction with the surrounding soil or other materials of the overall structure, and can also protect the geomembrane in the middle from external damage.
This 700-gram two-cloth and one-membrane composite geomembrane is widely used in various projects that require seepage prevention and reinforcement, such as landfills, tailings ponds, channel linings, dams, artificial lakes, waterproof layers of underground buildings and other fields.
