In large landfills and mining sites, sharp gravel backfills and heavy waste loads can easily puncture the vital underlying plastic geomembrane liner, leading to dangerous chemical leaks. Our heavy-duty staple fiber nonwoven geotextile cushion functions as an ultra-thick, shock-absorbing shield. This highly resilient protective filter mat deflects extreme point pressures from rocks and jagged stones, while its open pore structure allows toxic leachate liquids to flow smoothly into gas and fluid drainage pipes.

Technical Specifications

Why Choose Our Geotextile?

• Superior Needle-Punched Cushioning: Densely needle-punched to create a thick, springy fiber mat that excels at soaking up high-impact stone drops.

• Clog-Free Liquid Filtration: The engineered micro-openings act as a perfect filter, letting thick landfill leachate pass through constantly without blinding over.

• Immune to Harsh Chemical Leachate: The pure polymer fibers maintain their full strength and cushioning power when buried inside highly acidic or alkaline chemical environments.

• Custom Roll Diameters for Quick Unrolling: We can roll the fabric to large industrial dimensions, minimizing seaming steps and speeding up large-scale field deployments.

Primary Applications

• Landfill Liner Protection: Laid directly over or under HDPE geomembranes to cushion the plastic sheet against sharp stones in the waste mass.

• Leachate Collection Blind Ditches: Wrapping around perforated drainage pipes at the bottom of waste cells to filter out fine silt while letting liquids pass.

• Tailings Dam Filtration: Serving as a permanent filter layer on the interior slopes of mining slurry dams to prevent soil piping failures.

• Industrial Sludge Lagoons: Lining the structural banks of chemical containment zones to separate waste solids from drainage stone beds.
