What is a geotextile composite geomembrane?
A composite geomembrane liner bonds a polymer membrane to nonwoven geotextile by calendering or thermal lamination. The membrane forms the seepage barrier, while the textile provides cushioning and mechanical protection. Staple fiber and continuous filament nonwoven constructions are available.
Composite geomembrane for reservoir and canal lining
Applications include reservoir basins, dams, irrigation canals, water storage ponds, aquaculture ponds and civil works seepage control. Select the layer structure and mechanical grade for the subgrade, cover material and hydraulic conditions of the project.
One geotextile layer or two?
A one-geotextile/one-membrane construction has textile bonded to one face. A two-geotextile/one-membrane construction places textile on both faces. Specify the layer sequence, membrane thickness and textile type separately when comparing composite geomembrane quotations.
Specify membrane thickness and composite strength
Choose membrane thickness, total mass and nominal composite strength as separate specification fields. The tables below list hydrostatic pressure by layer structure and mechanical grades by nonwoven type.
