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.
