Geomembrane is a material used in soil protection and earthworks, also known as geosynthetics or geosynthetics.
It is usually made of high molecular materials such as polyethylene (PE) or polypropylene (PP), and has good permeability resistance, chemical corrosion resistance and aging resistance.
What are the types of geomembranes?
There are many types of geomembranes, mainly classified according to their material composition and usage. The following are some common types of geomembranes:
High density polyethylene (HDPE) geomembrane: It has high resistance to permeability and chemical corrosion, and is commonly used for impermeability and isolation layers.
Low density polyethylene (LDPE) geomembrane: It has good ductility and flexibility, and is commonly used in soil protection and Environmental engineering.
Linear Low Density Polyethylene (LLDPE) Geomembrane: It has excellent tear resistance and aging resistance, and is commonly used in projects that require higher strength and durability.
Polypropylene (PP) geomembrane: It has good impermeability and chemical corrosion resistance, and is suitable for various earthworks.
Polyvinyl chloride (PVC) geomembrane: It has good weather resistance and UV resistance, and is commonly used in water conservancy engineering, lake and river management, and other places.
Composite geomembrane: A composite geomembrane composed of two or more different materials, such as HDPE and LDPE, that combines the characteristics of both materials.
Three characteristics of LDPE geomembrane
Flexibility: LDPE geomembrane has good flexibility and plasticity, strong adaptability, and can adapt to soil deformation and geological changes.
Tear resistance: LDPE geomembrane has high tear resistance, which can effectively prevent soil from causing damage and damage to it.
Anti permeability: LDPE geomembrane has good anti permeability performance, which can effectively prevent the infiltration of water, liquid or gas, and is used for waterproofing, anti-seepage, and isolation engineering.
Chemical stability: LDPE geomembrane has good resistance to most acids, alkalis, salts, and chemical substances, and has high chemical stability.
Field of application: LDPE geomembrane is widely used in hydraulic engineering, Environmental engineering, road engineering, agricultural greenhouse and other fields, such as river restoration, landfill coverage, artificial lake seepage prevention, etc.
