How to deal with the edges of geomembrane? Edge treatment of geomembrane is an important step to ensure waterproofing effect. Here are some common geomembrane edge treatments: Buried soil treatment: The edges of the geomembrane can be buried underground and covered with a layer of soil or other suitable materials. This protects the edges from […]

Geomembranes and geotextiles Geomembranes and geotextiles are both geosynthetic materials, but they differ in structure, function, and application. Geomembrane: Construction: A geomembrane is typically a flexible, continuous membrane made from polymer materials such as polyethylene, polypropylene, or polyvinyl chloride. It is usually continuous without holes to provide waterproofing, insulation and soil protection. Function: Mainly used

Why is geomembrane important? Geomembrane plays an important role in civil engineering and environmental engineering, and its importance is reflected in many aspects: Anti-seepage effect: Geomembrane has anti-seepage properties and can effectively prevent water, chemicals, etc. from penetrating into the soil. This is critical in water conservancy projects, landfills, ponds and dams, to prevent groundwater

What is a geomembrane tank? Geomembranes are materials commonly used in fields such as civil engineering, environmental engineering, and water resources management to control soil erosion, prevent infiltration, filter water, or for other purposes. Geomembrane tank refers to the use of geomembrane as a water container for fish farming. Such a system is typically a

Is 2mm geomembrane suitable for fish farming? The use of 2mm geomembranes for fish farming may not be a common practice, as such membranes are usually used to prevent seepage and protect soil or bottom structures, rather than as part of the fish ecosystem in the water body. Fish farming requires some specific environmental and

Thermal expansion coefficient of geomembrane The thermal expansion coefficient of a geomembrane is a physical property that describes the dimensional changes of the geomembrane under temperature changes. Thermal expansion coefficient is usually expressed as linear thermal expansion coefficient (or linear expansion coefficient for short), which is a material property that reflects the length change of

Geomembrane elongation at break test The elongation at break test of geomembranes is a test method used to evaluate the tensile properties of geomembrane materials. This test is often used to determine how much stretch a geomembrane can withstand when a force is applied, and how far it can stretch during the stretching process. The
