PRODUCT DETAILS

Product introduction

HDPE rough surface geomembrane is a new type of seepage control material, single rough surface, double rough surface and other HDPE geomembrane has the function of increasing the coefficient of friction, anti-slip and so on, which can be applied to vertical seepage control of steep slopes and improve the stability of the project. Rough surface improves the friction performance of geomembrane surface, at the same time, compared with the same specification glossy membrane, rough surface of the membrane, when laying the membrane, it will make the membrane and the substrate to form a small clamping level, which can enhance the membrane's resistance to bearing deformation, - generally used in the slopes require a larger coefficient of friction in the project.

Performance characteristics

It has excellent temperature adaptability, weldability, weather resistance, good aging resistance, chemical resistance and environmental stress cracking resistance.

Purpose of action

Mainly used in landfill, sewage waste liquid treatment, water conservancy, mining engineering or waste residue treatment site as anti-seepage material. treatment site as anti-seepage material.

Construction technology

HDPE rough geomembrane is mainly used for slopes, its main function is anti-slip, paving should be rolled from top to bottom, the lap width between neighboring membranes is about 15cm. The width of the lap between neighboring membranes is about 15cm, and it is welded by automatic crawler welding machine.
