excellent water permeability pp non-woven geotextile

Brief introduction

Geotextile fabrics are non-woven fabrics which contain permeable membranes which allow water to pass through whilst still holding the particles in place. The fibers are needled to form a stable network that retains dimensional stability relative to each other.

Function

The main function of these geotextiles is to offer separation, filtration and primarily protection,

•      Separation and stabilization in road and railway construction

•      Prevention of soil movement in erosion control measures

•      Cushioning and protection in many containment projects.

Advantages

1) Isolation

The use of geotextile different physical properties (particle size, distribution, density and thickness, etc.) materials (such as soil and sand and gravel soil, soil and concrete, etc.) for isolation. So that two or more materials are not loss of inter-and non hybrid,to maintain the overall structure of the material and functions of the structures is to strengthen the load bearing capacity.

2) Filter

When the water from fine materials into the soil layers of rough material, the use of acupuncture geogextile good air and water permeability, so that the water flow through, and effective interception soil particles, spinning, the small stone so as to maintain the stability of the soil and water projects.

3) Drainage

Acupuncture geotextile is a good hydraulic material, which can from a soil internal drainage channel, soil structure and excess liquid gas emissions.

4) Reinforced

Acupuncture use of geotextile to enhance soil and the tensile strength of the antideformation ability to increase the stability of the building structure in order to improve the quality of the soil.

5) Protection

Will focus on effective stress-proliferation, transfer or broken down by external force to prevent the soil and damage.

6) Closed

Acupuncture geotextile and other materials (primarily asphalt or plastic film) with the formation of impermeable layer of insulation layer. (Mainly used for road resurfacing and repairing, etc.)
