Papua New Guinea Soil anti-seepage 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

Geomembrane is an impermeable material used to form an isolation layer between soil and water, mainly used in the following areas:

Soil anti-seepage: Geomembrane can prevent water from seeping through the soil to the underground water layer below, playing a role in anti-seepage. It is widely used in water conservancy projects such as embankments, ditches, canals, reservoirs, and agricultural projects such as farmland, orchards, and vegetable greenhouses to prevent water loss and excessive infiltration.
Soil water retention: Geomembranes can prevent water from penetrating deep into the soil, playing a role in water retention. It is commonly used in farmland, gardens, green spaces, and other places in arid areas, which can reduce water evaporation and soil water loss, and provide stable water conditions.

Applications

geomembranes are impermeability, water retention, soil stability, soil pollution prevention, and the formation of isolation layers. They play an important role in fields such as water conservancy engineering, agricultural engineering, environmental engineering, and road engineering.

Working Drawing

Soil stability: Geomembranes can help increase the shear strength and erosion resistance of soil, improving soil stability. It can be used for the reinforcement and protection of soil slopes and castles, to prevent soil landslides and collapses, and to maintain the stability of slopes.

Preventing soil pollution: Geomembranes can prevent harmful substances, chemicals, and heavy metals from infiltrating into groundwater and water bodies, playing a role in preventing soil pollution. It is commonly used in industrial sites such as urban landfills, hazardous waste disposal sites, and chemical plants to protect the safety of groundwater and the surrounding environment.

Isolation layer: Geomembrane can also form an isolation layer between different soil layers, preventing the exchange and mixing of different types of soil, and maintaining the independence of various soil layers. It is commonly used in road engineering such as roads, railways, airports, etc. to prevent mutual infiltration and influence between different soil layers.
