Composite Geomembrane Durable and Impermeable for Optimal Performance and Protection
Product Introduction
Composite geomembrane is composed of one or more layers of geotextiles and one or more layers of polymer materials by calendering and hot melt. Its thickness is usually expressed as a“Sandwich” of 200 grams of geotextiles, 0.5 mm of polymer film, and another layer of 200 grams of geotextiles. This structural design not only provides the necessary strength and durability, but also ensures good impermeability
Product Properties
-
Good physical mechanical properties
-
Withstand environmental factors
-
Ultraviolet (UV) Resistance: May be exposed to sunlight, requiring adequate UV resistance to prevent rapid aging and damage during use.
-
Resistance to hydrolysis: Can resist hydrolysis under different humidity conditions, maintaining stable material performance.
-
Withstands High and Low Temperatures: Designed to adapt to temperature changes when in contact with materials like asphalt, featuring a high melting point to function properly in varying temperature environments.
-
Good chemical stability
-
Due to the complex conditions of water and soil, such as alkalinity, acidity, and high salt content, composite geomembranes must possess the characteristics of chemical resistance, corrosion resistance, and mold resistance.
-
With certain permeability
-
In engineering scenarios where filtration and drainage are required, composite geomembranes have good water permeability, which can meet the needs of water flow.
Product Application
Composite geomembranes are widely used in various fields due to their excellent impermeability, protection, reinforcement, and other properties.
♦ Municipal construction: includes impervious lining for subways, basements and tunnels.
♦ Environmental Protection: anti-seepage treatment of landfill.
♦ Agricultural Water Conservancy: anti-seepage pavement of irrigation system.
♦ Traffic facilities: highway, railway subgrade anti-seepage treatment.
