When there is seepage in the soil, it is often accompanied by seepage deformation, such as piping and flowing soil. This should be paid attention to in the excavation of embankments and foundation pits. On the one hand, the hydraulic gradient can be reduced by means of anti-seepage, precipitation or

Waterproof And Crack-proof Layer Fabric In highway

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

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
