overview
Compound geomembrane, a waterproof material, compound with geotechnological fabric and geomembrane, it is used for draining off water and adding the muscle mainly.
character
Width 4-6m weight 200-1500g/m2
The geomembrane is against drawing, tearing resistance, and high CBR plunger strength, can meet the need of civil engineering such as water conservancy, municipal administration, building, traffic, subway, tunnel etc. Because of selecting high polymer materials for use and adding the aging-resistant materials in the production technology, it can use in the unconventional temperature environment.
character
geomembrane used in place of granular materials as a geomembrane layer of protection, to protect the geomembrane from damage, Reduced cushion size gradation requirements, and can play the role of drainage.
it has large coefficient of friction, to prevent the cover slip,better than only HDPE.
Compound geomembrane has higher tensile,strength, bursting, puncture
Compound geomembrane has good deformation, Strong adaptability.
Consistent with the geomembrane and the soil contact surface of pore pressure and uplift forces of floating easily dissipated
the compound membrane has insulation effect,and down the damage to the geomembrane,so decrease the Deformation
with the use of embedded geomembrane laying, Has excellent anti-aging properties, a reduction of maintenance works, maintenance
with the simple construction,lower traffic, reduce the project cost, Shortened the duration
type
according the Composite approach
One piece of geotextile and one piece of membrane;weight of base geotextile:100-700g/m2;weight of Non-woven 200-600g/m2.
two piece of geotextile and one piece of membrane;weight of base geotextile:100-700g/m2;weight of Non-woven 200-600g/m2.
Filament composite geomembrane due to the geotextile composite fiber length, needle cutter and more tensile strength than the short wire, and the general conditions of use in bad matrix, easily lead to acts of foreign bodies in puncture sites
Short because of the silk composite geomembrane composite geotextile fiber long, twisted and multi-needle, filament tensile strength than the bad, the general use of bad conditions in the matrix will easily lead to acts of foreign bodies in puncture sites
