Product Description

Non Woven Needle Punched Polyester Geotextile Fabric (HP-7)
Geotextiles is a new type of building materials, raw materials are polyester, polypropylene, acrylic, nylon and other synthetic polymers. The manufacturing method is divided into: Woven and nonwoven geotextile geotextile types. General construction is mainly used in non-woven geotextile. Impermeable geotextile, filtration, drainage, separation, reinforcement, protection, sealing and other functions, it is compared with the conventional masonry and concrete materials seepage effect, with low investment, simple construction technology, short construction period, anti-seepage effect, the effective channel utilization factor advantages.
Non Woven Needle Punched Polyester Geotextile Fabric (HP-7)
1: Isolation
Polyester staple fiber geotextile use acupuncture for building materials with different physical properties ( particle size distribution, consistency and density, etc. ) of ( such as soil and sand, soil and concrete, etc. ) in isolation. Between two or more materials so that no loss, do not mix, keeping the overall structure and function of materials, so that structures containing supporting capacity strengthening.
2: Filter ( filtration )
When water flows into the soil coarse material from fine soil material, the use of polyester staple acupuncture geotextile good air permeability and water permeability, water flow
By effectively carrying soil particles, sand, small stones, etc., in order to maintain a stable soil and water engineering.
3: Reinforcement
Polyester staple fiber geotextile use acupuncture to enhance the tensile strength of the soil and resistance to deformation, enhance the stability of the building structure to change
Body mass good soil.
4: Protection
When the flow of soil erosion, the effective stress will focus on proliferation, transfer, or decomposition, to prevent soil and damage by external force, which protect the soil.

( 2 ) reinforced flexible pavement, repair cracks on the road surface to prevent reflective cracking.
( 3 ) increase the gravel and reinforced soil slope stability, to prevent frost damage when soil erosion and low temperatures.
( 4 ) isolation layer path between the ballast and subgrade, or isolation layer between the roadbed and the soft base.
( 5 ) manual filling, isolation and foundation rubble or materials field isolation layer between different permafrost. Filtration and reinforcement effect.
( 6 ) ash storage dam or tailings dam upstream face of the initial filter layer, retaining wall backfill drainage systems filter layer.
( 7 ) Drainage Ditch drainage underground pipe or gravel surrounding the periphery of the filter layer.
( 8 ) Water Project wells, wells or vacuum filter layer baroclinic tube.
( 9 ) highway, airport, railway track and artificial rockfill such as twitter and geotextile separation layer between the foundation.
