HDPE Smooth Geomembrane

Product details

Products Description

The general characteristics of HDPE smoothÂ geomembrane include physical properties, mechanical properties, chemical properties, thermal properties and durability. Geomembrane in engineering applications pay more attention to its waterproof performance, deformation resistance and durability. A large number of engineering practices have proved that geomembranes have good impermeability. Have good elastic strain capacity, can withstand different construction conditions and working stress; Has good aging resistance, in the underwater, HDPE SmoothÂ geomembrane durability is particularly outstanding.

HDPE Smooth Geomembrane Property Analysis

Physical Property

Q:Â Density

A:the density of HDPE geomembrane is 0.941-0.960.

Q:Â Thickness

A:Â BPM Geosynthetics geomembrane thickness is 0.2mm to 3.0mm.

Mechnical Property

Q:Â Tensile strength

A:Â Compared with other materials, HDPE Geomembrane has higher tensile strength and longer elongation. BPM laboratory carry out the experiment according to ASTM GRI GM13. mainly by wide strip stretching and Axisymmetric bursting method.

Q:Â Welding seam tensile strength

A:Â Weld strength is generally lower than the tensile strength of the geomembrane itself. The weld strength is also related to different welding methods, and the Hot wedge welding strength is the highest, which is close to the strength of geomembrae base metal. So when welding, customers generally choose to use the welding machine for double weld hot wedge welding.

Q:Â Tear strength

A: Tearing strength is tearing resistance of the geomembrane.

Q:Â Puncture strength

A: Puncture resistance of geomembrane can be improved by laying geotextile above and below geomembrane.

Q:Â Friction coefficient

A:Â The friction coefficient of different types of geomembranes is very different. The friction coefficient of smooth geomembranes and soil is the smallest. If you want to improve the friction coefficient of geomembranes and other geomembranes and the stability of composite impermeable system, you can use rough/textured geomembranes or composite geomembranes.

The durability of geomembranes

The aging problem of geomembrane is mainly related to two aspects, the first is the type and characteristics of the polymer, and the second is the working conditions of the geomembrane and the surrounding environment.

Current research show that, HDPE geomemofilm is not easy to aging, and like PVC film, it is easy to aging.
