Protect Surrounding Soil and Groundwater with Impermeable HDPE Textured Geomembrane
Product Introduction
Column Point Geomembrane is a type of impervious material made from high molecular polymer as the basic raw material. The column points on the membrane surface are pressed and stretched by a special mold roller, resulting in uniform and aesthetically pleasing distribution. These column points can increase the friction coefficient. The front and back sides of the membrane can be fused into a single piece with different materials and colors through heat fusion.
Properties of the Punctured Geomembrane
Good Coefficient of Friction
Aesthetics
Integration of Different Materials and Colors
Resistance to Environmental Stress Cracking (ESC)
Mechanical Properties
Outstanding Tensile, Abrasion, and Puncture Resistance
Good elongation
Other Features:Temperature Adaptability ,Weather resistance,Root Penetration Resistance
Application Areas
Green Engineering
-
Landfill: Prevents leachate from seeping out and polluting the surrounding soil and groundwater. The impermeable and puncture-resistant properties of the column point geomembrane are fully utilized here, as there are various sharp objects in the landfill that may cause puncture damage to the geomembrane. The puncture resistance of the column point geomembrane can effectively resist such damage.
-
Wastewater or Waste Residue Treatment Site: Used for imperviousness to prevent wastewater seepage or harmful substances from waste residue seeping out. Its chemical corrosion resistance and impermeability ensure environmental safety of the treatment site.
-
Construction Engineering
-
Basement Waterproofing: As the waterproof layer for the basement, it prevents groundwater from seeping into the basement, ensuring the dryness and usability of the basement. The waterproof and impermeable properties of the column point geomembrane, along with its excellent mechanical properties, can adapt to the complex environment of the basement.
-
Roof Waterproofing: In roof engineering, it plays a waterproof role, resisting rainwater penetration. Its weather resistance and puncture resistance can cope with various destructive factors that the roof may encounter, such as wind, sun, rain, and pedestrian traffic.
-
Water Conservancy Project
-
Dike, Dam, and Reservoir Seepage Control: Utilizing its impermeable properties, it prevents water seepage, ensuring the water storage and safe operation functions of hydraulic facilities. The environmental stress cracking resistance and good extensibility of the geomembrane can adapt to the deformation needs of dikes, dams, and reservoirs under different water levels and pressures.
-
Channel and Reservoir Seepage Prevention: Effectively prevents water seepage in channels and reservoirs, improving the utilization efficiency of water resources. Its excellent seepage prevention performance and adaptability to deformation can meet the usage requirements of channels and reservoirs.
-
Traffic Engineering
-
Road Tunnel, Subway, Railway Tunnel Waterproofing: Prevents groundwater from seeping into tunnels, ensuring the dryness and safety of tunnel interiors. The waterproofing and puncture resistance of column point geomembrane can guarantee the stability and safety of tunnels during construction and use.
