What are the types of geomembranes?

Geomembrane is a synthetic waterproof material in civil engineering, including polyethylene, polyvinyl chloride, ethylene vinyl acetate and other types. It has waterproof, anti-seepage and isolation properties. When selecting, factors such as performance, mechanics, and environmental protection must be comprehensively considered based on project needs, and construction specifications must be followed.

Geomembranes can be categorized into various types according to different application scenarios and performance requirements. Several common types of geomembranes are described in detail below.

1 Polyethylene (PE) Geomembrane

Polyethylene geomembrane is a waterproof and seepage-proof material processed with polyethylene resin as the main raw material. It has excellent water resistance, chemical resistance and aging resistance, as well as high tensile strength and elongation. Polyethylene geomembrane is widely used in water conservancy projects, environmental protection projects, landfills and other fields.

2 Polyvinyl chloride (PVC) geomembrane

pvc geomembrane is a waterproof and seepage control material processed with polyvinyl chloride resin as the main raw material. It has excellent water resistance, chemical resistance and aging resistance, and also has good UV resistance. PVC geomembrane is suitable for water conservancy engineering, transportation engineering, environmental engineering and other fields.

3 Ethylene vinyl acetate (EVA) geomembrane

Ethylene vinyl acetate (EVA) geomembrane is a waterproof and seepage control material made of ethylene vinyl acetate copolymer as the main raw material. It has excellent water resistance, chemical resistance and aging resistance, as well as good tear strength and puncture resistance. Ethylene vinyl acetate geomembrane is suitable for landfills, sewage treatment sites and other occasions that need to withstand large external forces.

4 Composite geomembrane

Composite geomembrane is made of two or more layers of different materials of geomembrane after composite processing of waterproof materials. Common composite geomembrane PE / EVA composite geomembrane, PVC / EVA composite geomembrane. Composite geomembrane combines the advantages of different materials, with higher waterproof, seepage control performance and stronger mechanical properties. It is widely used in water conservancy engineering, transportation engineering, environmental engineering and other fields.

5 bentonite waterproofing blanket

Bentonite waterproofing blanket is a bentonite as the main raw material, processed through a special process of waterproofing materials. It has excellent waterproofing, seepage control performance and a certain self-repairing ability, and at the same time has good environmental performance. Bentonite waterproofing blanket is suitable for water conservancy engineering, environmental engineering, garden engineering and other fields.

6 HDPE seepage control membrane

HDPE seepage control membrane is high density polyethylene (HDPE) as the main raw material, processed waterproof, seepage control materials. It has excellent water resistance, chemical resistance and aging resistance, while having high strength and toughness.HDPE seepage control membrane is suitable for water conservancy projects, environmental protection projects, landfills and other fields, especially for the need to withstand greater water pressure and geological stress occasions.

7 GCL bentonite waterproof mat

GCL bentonite waterproofing mat is a bentonite particles and special composite short fibers as the main raw material, processed through a special process of waterproof materials. It has excellent waterproofing, seepage control performance and a certain self-repair ability, while having good environmental performance.GCL bentonite waterproofing mat is suitable for water conservancy projects, environmental engineering, garden engineering and other fields, especially for the need for rapid installation and repair of the occasion.

8 Conclusion

In short, there are many types of geomembranes, and different types of geomembranes have their own characteristics and applicable occasions. When choosing geomembranes, the most suitable type of geomembrane should be selected according to the specific needs and actual situation of the project, taking into account its waterproofing, seepage control performance, mechanical properties, environmental performance and other factors. At the same time, in the construction process, the construction should be carried out in strict accordance with the relevant norms and requirements to ensure the quality and effect of the geomembrane.
