ASTM 1.5mm Geomembrane Pond HDPE Liner

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

Our high density polyethylene (HDPE) geomembranes provide an impermeable barrier against a wide range of solids and liquids. They exhibit excellent chemical and UV resistance,impermeability, and high yield and welded seam strengths, which is widely used as the liner.(model according to the thickness of distinction, different thickness and different price) production capacity: thickness:0.1 mm -6 mm, width: 1-8 meters. It is suitable for seepage control in special industries, and is widely used for aquaculture, seepage control, reservoirs or sewage treatment ponds.

Applications

Geomembrane has a wide range of application fields, mainly including but not limited to the following aspects: (1)Waterproof works: Waterproof barriers for all kinds of engineering projects, such as basements, tunnels, reservoirs, river embankments and water conservancy projects, effectively prevent water penetration and leakage. (2)Soil isolation: Used to isolate different soil layers or to stop contaminants from seeping into groundwater, such as in landfills, chemical plants, and wastewater treatment facilities. (3)Soil stabilization and reinforcement: Used for the reinforcement and stabilization of soil, used in roads, railways, airports, retaining walls and land backfill and other engineering projects to enhance the stability and bearing capacity of the structure. (4)Environmental protection: Used for environmental remediation and protection works to close or isolate contaminated land areas to prevent the spread of pollutants. (5)Hydraulic engineering: In coastal protection, DAMS, water channels and artificial islands and other hydraulic engineering, to prevent water infiltration and erosion. (6)Landscape design: Applied in landscape and landscape design as ground cover material, protect soil and vegetation, control water penetration. (7)Mining and industrial applications: Used in mines, chemical plants and industrial facilities as an impermeable layer to prevent waste or harmful substances from leaking and protect the environment.
