What’s Composite Geomembrane?
Lianyi® Composite Geomembrane is a popular geosynthetic material made by calendering and hot melting two or more materials, namely geotextile (long fiber needle punched non woven geotextile , short fiber needle punched non woven geotextile,woven geotextile,etc.) and high molecular materials (HDPE geomembrane, LDPE geomembrane, EVA geomembrane, etc.).
Classification Of Composite Geomembrane
One geotextile+one geomembrane, geotextile: 100-1000g/m2,geomembrane:0.2-2.0mm
Two geotextiles+one geomembrane, geotextile: 100-1000g/m2,geomembrane:0.2-2.0mm
One geotextile+two geomembranes, geotextile: 100-1000g/m2,geomembrane:0.2-2.0mm
More geotextiles+ more geomembranes, geotextile: 100-1000g/m2,geomembrane:0.2-2.0mm
One geotextile one geomembrane, geotextile: 100-1000g/m2,geomembrane:0.2-2.0mm
Features Of Composite Geomembrane
Composite geomembrane uses geotextile instead of granular materials as the protective layer of the geomembrane to protect the anti-seepage layer of the geomembrane from damage, reduce the gradation requirements of the cushion layer particle size, and also play a drainage role
The composite geomembrane has a large friction coefficient, which can prevent the sliding of the covering layer. Compared with the simple HDPE film, the non-woven fabric in the composite geomembrane has a larger friction coefficient. The composite geomembrane can increase the slope ratio and reduce the occupied area
The mechanical strength of the composite geomembrane, such as tensile, tear, puncture and puncture resistance, is high
Composite geomembrane has a certain degree of deformation, and the stress transmission and dispersion caused by the concave-convex defects of the base layer are relatively fast, so it should have a strong capacity
The pore pressure and buoyancy force on the contact surface between the composite geomembrane and the soil are easy to dissipate
Composite geomembrane has a certain heat preservation effect, reducing the damage to the geomembrane caused by soil frost heaving, thereby reducing soil deformation
The composite geomembrane is laid in an embedded manner and has excellent anti-aging performance, reducing the maintenance and upkeep of the project
The construction of composite geomembrane is convenient, reducing the transportation volume, lowering the project cost and shortening the construction period
