Brazil Special size customization HDPE 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

The specifications of geomembranes can vary according to different application requirements and engineering requirements. Here are some common specifications for geomembranes

1.Thickness: The thickness of geomembrane is usually between 0.2mm and 3.0mm, and different thicknesses are suitable for different application scenarios. Thin geomembranes are suitable for light load sites, while thicker geomembranes are suitable for sites that can withstand larger loads or require higher anti-seepage capabilities.

2.Width: The width of the geomembrane is usually between 1m and 8m, and can also be customized according to needs. The selection of width should be determined based on specific engineering requirements and the conditions of the laying site, to ensure that the coverage area is fully covered and the expected effect is achieved.

Applications

3.Strength: The strength of geomembranes is evaluated through tensile testing, and common strength indicators include tensile strength and tear resistance. Different engineering requirements may require different strength levels of geomembranes to ensure their durability and stability during use.

4.Color: Geomembranes are usually divided into two colors: black and transparent. Black geomembrane can better absorb heat under sunlight and is suitable for applications that require increasing soil temperature; Transparent geotextile can allow light to pass through, making it suitable for agricultural cover applications that require light.

Working Drawing

It should be noted that the specific specifications of geomembranes may also be related to factors such as geographical environment, engineering design, and regulatory standards. Therefore, in actual use, it is necessary to choose and apply them according to specific circumstances.
