Road and railway subgrade projects are built in saline soil areas and water-rich soft soil areas, and composite geomembrane is laid at the bottom of the subgrade, which can effectively limit the migration of salt and has waterproof effect. Geomembrane can form a barrier layer to limit or even comple

1. The composite geotechnical drainage net is a new type of geosynthetic material made of random wire melted and laid. It has high pressure resistance, large opening density, and has the functions of all-round water collection and horizontal drainage.2. After the composite geotechnical drainage net

Polypropylene filament geotextile adopts advanced spinning equipment, the monofilament fineness can reach above 11dex, the strength can reach above 3.5gd, the mesh is evenly laid without cloud spots, the vertical and horizontal strength and elongation are consistent, and the product performance is m

Geotextiles are textiles used in civil engineering. Geotextiles in a narrow sense are permeable textiles used in civil engineering with civil technical materials. The impermeable textile is called a geomembrane, and the geomembrane is generally obtained by coating the textile with asphalt or other c

High-strength seepage drainage filter pad (geowork mat) is a kind of drainage geotechnical material made of industrial polypropylene (PP) or polyethylene (PE) as raw materials and melted and laid with random wires. It has the functions of high pressure resistance, large opening density, all-round wa
