Specifications
Three-dimensional Geonet1.Aging resistance
2.Erosion resistance
3.Good flexibility
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.
Functions
1.Use of geotextile good air permeability and water permeability, so that the water flow through in order to retain effective loss of sand.
2.Geotextile has a good hydraulic performance, it can form a soil internal drainage channel, soil structure and excess liquid gas efflux.
3.Use of gotextile to enhance soil and the tensile strength of the anti-deformation ability, and enhance the stability of the building structure in order to improve soil quality.
4.Effective stress will focus on proliferation, transfer or broken down by external force to prevent the soil and damage.
5.Lower on the prevention of gravel, soil and concrete mixed between.
Mesh plug is not easynot because of the formation of fibrous tissue type of network and strain of movement.
6.High-permeable-water in the soil under the pressure to maintain good water permeability corrosion-resistant-light and easy to use, simple construction.
