Texture HDPE Geomembrane for Environmental Protection

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.

Description

Introduction

Texture HDPE Geomembrane is a impermeable polymer liner and the largest type of geosynthetics. It is used for a wide and growing range of applications, including fish water ponds, shrimp water ponds, artificial lake, landfills, lagoons, channels and ornamental ponds, and are found in environmental, geotechnical, transport and hydraulic applications, in addition to other engineering works.

Texture HDPE Geomembrane is a black, high quality, high density polyethylene (HDPE) geomembrane produced from specially formulated polyethylene resin. The polyethylene resin is designed specifically for flexible and durable geomembrane applications.

Texture HDPE Geomembrane contains approximately 97.5% polyethylene, 2.2% carbon black and trace amounts of antioxidants and heat stabilisers. HDPE Smooth Geomembrane has outstanding chemical resistance, mechanical properties, environmental stress crack resistance, dimensional stability and thermal aging characteristics.

Applications

Good permeability: The texture design on the surface of the textured geotextile can improve the permeability of the geotextile, and has good effects in drainage and anti-seepage.
Easy to apply: Textured geotextiles typically have flexibility and flexibility, making them easy to cut and lay on the construction site, saving construction time and costs.
Environmental protection and renewable utilization: Some textured geotextiles are made of environmentally friendly materials, which have the characteristics of renewable utilization and are in line with the concept of sustainable development.

Overall, textured geotextiles have the characteristics of high strength, good waterproofing, corrosion resistance, and easy construction, making them one of the commonly used protective materials in engineering construction.
