HDPE Textured Geomembrane Strong Tensile Strength for Seepage Prevention in Dike Construction
Product Introduction
Spray Coarse Geosynthetics Membrane is a special geosynthetic material. It is produced on the basis of traditional polyethylene impervious membrane production technology by updating production equipment to form a granular rough surface on the produced geomembrane. This design not only improves the frictional performance of the geomembrane surface but also has stronger tensile strength compared to the same specification smooth film.
Product Properties
Spray Rough Geomembrane has various performance characteristics that make it excel in impervious engineering. Firstly, its impermeable effect is reliable with a small permeability coefficient, effectively preventing the infiltration of liquids and gases. Secondly, the construction laying is relatively easy, suitable for large-scale engineering applications. In addition, the tensile strength, elongation at break, and puncture resistance of the spray rough geomembrane are strong, with stable material properties that can resist the erosion of various chemical reagents. The seams are connected by double-seam hot welding, with high seam strength and less likelihood of leakage.
Product Application
The application field of the sprayed rough geomembrane is very extensive. It can be used for landfill sites, tailings storage sites, channel seepage prevention, dike seepage prevention, and subway projects, etc. In these projects, the sprayed rough geomembrane can not only play a seepage-proof role but also enhance the membrane's anti-bearing deformation force, suitable for slope membrane surface projects that require covering soil and have a large friction coefficient.
To sum up, the spray-coated geomembrane is a high-performance impervious material. Its unique design and excellent performance make it play an important role in various impervious projects. During the construction process, attention should be paid to the relevant technical requirements to ensure the quality and effect of the project.
