PP Biaxial Geogrid
PP Biaxial geogrid is an integrally formed biaxial geogrid consisting of high quality polypropylene and carbon black. The punched and drawn manufacturing process are so designed that they provide the lateral confinement and helps in reinforcing the weak soils.
Introduction:
High-strength Biaxial plastic geogrid for road base and sub-base stabilization. This geogrid is being manufactured from polypropylene raw materials: They are polymer coated for high UV-stability and low installation damage. This kind of material has high tensile longitudinally and horizontally, which can be used to reinforce the basement.
Features:
1. High tensile strength in the warp and weft directions.
2. Low elongation.
3. Good anti-aging, acid and alkali-resistance

Application:
It can be applied in all kinds of roads, railways, airports to enhance the roadbed.
It can be applied in a large car park and terminal freight yard, etc., to strengthen the foundations of a permanent load.
It can be applied in rail, road slope's protection.
It can be applied to enhance the culvert.
It can be applied as a secondary enhancement after the uniaxial geogrid soil enhancement, further enhance the soil, prevent soil erosion.
It can be applied in mining, tunnel reinforcement.
