Composite Geomembrane

What is a composite geomembrane?

A composite geomembrane is made from a PE / HDPE geomembrane laminated with one or two layers of nonwoven geotextile. Categories include geotextile-and-geomembrane (one-cloth-one-membrane), geomembrane with nonwoven geotextile on both sides (two-cloth-one-membrane), and multi-layer geotextile-and-geomembrane build-ups. The geomembrane provides the impermeable anti-seepage barrier while the bonded geotextile protects it and adds friction.

Why buyers choose a geotextile composite geomembrane

Pairing the membrane with a nonwoven geotextile solves the two biggest field problems of a bare liner: puncture from the subgrade and sliding on slopes. The geotextile cushions the PE geomembrane against stones and roots and raises the friction coefficient, while the membrane keeps the structure watertight. This GM-GT composite liner is used across water conservancy (reservoir, dam and canal seepage control, vertical core walls, slope protection), environmental works (landfill, sewage and hazardous-waste sites), municipal works, gardens (artificial lakes and pond lining), petrochemical and mining (tailings ponds, heap leach and sedimentation tanks) and agriculture (irrigation and storage ponds).

Constructions and how it relates to our other products

The composite is built from the same materials we supply individually — a PE/HDPE membrane bonded to nonwoven fabric. Where a project needs only the bare barrier, see our HDPE geomembrane; for the full liner range and surfaces, browse the geomembrane category, or compare related barriers under geomembrane products. We confirm the geotextile mass-per-area and membrane thickness against the agreed grade for each order.

How the composite geomembrane is made

The composite geomembrane is produced by laminating a PE / HDPE geomembrane core to one or two layers of nonwoven geotextile so the two function as a single roll. Construction codes include one-cloth-one-membrane (fabric on one face), two-cloth-one-membrane (fabric on both faces) and multi-layer build-ups. The membrane supplies the impermeable anti-seepage barrier while the bonded geotextile cushions it and adds friction. The geotextile mass per unit area and membrane thickness are selected to match the hydraulic head and subgrade of each project.

Applications across many industries

Our geotextile composite geomembrane is widely used across water conservancy (reservoir, dam and embankment seepage control, plugging, reinforcement, canal and vertical core-wall lining, slope protection), environmental protection and sanitation (domestic waste landfill, sewage treatment, toxic and hazardous-materials disposal sites, industrial waste), municipal works (metro, underground structures, roof storage tanks and gardens), gardens and landscaping (artificial lakes, golf-course and fish ponds), petrochemical works (refineries, oil and chemical storage, sedimentation tanks) and mining and agriculture (heap leach tanks, tailings ponds, storage yards, irrigation and drinking-water ponds).

Standards, quality and service

No single public statutory ASTM or GRI standard governs the finished cloth-and-membrane laminate as one product; in the Chinese market the GM-GT composite liner is commonly produced to GB/T 17642 or to manufacturer specification, with each constituent layer tested to its own method. We confirm the construction code, geotextile mass per unit area, membrane thickness and roll size against your order and supply a datasheet with each shipment. Tell us the application, hydraulic head and subgrade and we will recommend a construction and grade, then ship from our factory.
