The role and advantages of using geomembrane and geotextile in combination

Combination effect

Geomembrane: the main impermeable layer; geotextile: a combination of protective layer, drainage layer, and reinforcement layer to form an integrated structure of impermeability, protection, drainage, and reinforcement.

Specific role

Seepage Prevention and Water Stopping (Core Function)
Geomembrane (HDPE, LDPE, PVC, etc.) is an impermeable membrane material that blocks the leakage of water, leachate, sewage, and chemicals.

Uses: Landfills, tailings ponds, sewage treatment plants, fishponds, artificial lakes, tunnel waterproofing linings, etc.

Protecting the geomembrane from punctures and scratches
Geotextile is laid on the top and bottom sides of the membrane to isolate it from sharp stones, tree roots, and hard objects.

Preventing damage to the geomembrane layer from construction compaction, settlement, and punctures.

Drainage, water conduction, and air ventilation
The porous and permeable geotextile allows seepage water, groundwater, and gas to be discharged.

Reducing water pressure on the geomembrane, preventing bulging and damage.

Reinforcing and stabilizing the soil
Geotextile enhances the integrity of the soil, reducing uneven settlement, slippage, and cracking.

Improving the stability of slopes, roadbeds, and embankments.

Filtration and reverse filtration

Advantages of using in combination

Adaptable to Complex Topography and Settlement Reinforcement + Drainage: The project is more stable and suitable for soft foundations, slopes, and mountainous areas.

Environmental Compliance: Meets environmental standards for seepage prevention in landfills, sewage treatment plants, and hazardous waste storage facilities.
