TR-dimension composite geonet for drainage

Tri-dimension composite geonet 1)Good water conductivity 2)filtration-drainage-protection 3)compression load>2000Kpa

prefabricated drains  Tri-dimension composite geonet for drainage :

prefabricated drains

Tri-dimension composite geonet for drainage is made of a unique tri-dimension geonet adhibited geotextile on both sides. It has the property of geotextile(filtration function) and geonet(drainage and protection) and provide a function system fitration-drainage-protection .The core of net with its unique tri-dimension structure can bear higher compressiong load in construction and remain the certain thickness,provide good water conductivity.

Typical applications

Landfill drainage;roadbed and road drainage; railway drainage ,tunnel drainage,underground structure drainage, the retaining back wall drainage , gardens and sports grounds drainage.

Features and so on

Excellent drainage function, can bear long time hige press load

High tensile and shear strength

Reduce the rate geotextile embedding into the core of geonet, can protect long time stable water conductivity

Tri-dimension composite geonet for drainage can bear more than kpa compression load

Its anti-compression capacity is much larger than common geonet for drainage.
