sao tome and principe Waterproof Geomembrane HDPE Geomembrane Price HDPE Pond Liner Geomembrane

Geomembranes use plastic movies as anti-seepage substrates, commonly which encompass polyvinyl chloride (PVC) and polyethylene (PE), EVA (ethylene/vinyl acetate copolymer). In tunnel applications, ECB (ethylene vinyl acetate modified asphalt combo geomembrane) is moreover designed and used.

Product Description

Introduction

High density polyethylene(HDPE) clean geomembrane, made of virgin resin via distinct production, has even and clean floor on each sides. It is specially designed for bendy geomembrane. Thickness stages from 0.2mm to 2.0mm, width from 1m to 8m. The roll size can be made in accordance to layout or consumer request.

HDPE clean geomembrane has tremendous chemical and mechanical property, anti-crack property, dimensional steadiness and anti-aging property, moreover it can be uncovered for anti-UV property.

Municipal environmental, anti seepage in landscaping and municipal, metallurgy area, anti-corrosion, transportation infrastructure, agriculture reservoir waterproofing project, fisheries aquaculture. Other services waterproofing, anti erosion, anti seepage, reinforcement and seepage water collecting, instruction of brief tank and one of a kind structure.
