Polypropylene Short Fiber Geotextile
1. Use the good air permeability and water permeability of polypropylene geotextile to allow water to flow through, thus effectively trapping sand and soil loss.
2. Polypropylene geotextile has good water-conducting properties, it can form a drainage channel inside the soil body, the excess liquid and gas drainage within the soil structure.
3. The use of geotextile to enhance the tensile strength and deformation resistance of the soil body, enhance the stability of the building structure in order to improve the quality of the soil body.
4. effectively diffuse, transfer or decompose the concentrated stress to prevent the soil body from being damaged by external force.
5. Prevent mixing between the upper and lower layers of gravel, soil and concrete.
6. Mesh holes are not easy to be blocked, because the mesh structure formed by indeterminate fibre tissue has strain and movement.
7. High water permeability, under the pressure of soil water, it can still maintain good water permeability.
8. corrosion-resistant, with polypropylene chemical fibre as raw material, acid and alkali resistant, non-corrosive, non-insect moth, anti-oxidation.
9. Simple construction, light weight, easy to use.
Product description
Polypropylene geotextile has good physical and mechanical properties, in water conservancy and transport and other projects have a very broad application prospects. In the Netherlands famous sea defence project, due to the construction of huge dykes when a large number of geotextiles, making the world's largest adjustable tidal barrage in 200 years of safe use. The United States in the upper reaches of the earth and stone dams with a large number of geotextiles for the slope anti-filtration. According to the National Bureau of Statistics, the annual economic loss caused by flooding in China is about 400 billion yuan. If the use of geotextiles and geogrids in the construction of dams, you can build a strong dam to prevent flooding caused by economic losses. Polypropylene geotextile plays a good effect in the dike protection project which is difficult to be achieved by other materials.

Application
Polypropylene geotextile can be widely used in hydropower, roads, railways, ports, airports, sports stadiums, tunnels, coastal mudflats, reclamation, environmental protection and other fields to isolate
Almost all foreign high-grade highway construction use geotextile, our country is also in the application. The application of geotextile in highway engineering can effectively reduce rutting deformation, prevent and inhibit reflection cracks, and delay the fatigue damage of the road. In the construction of high-grade highways, the use of geotextiles can reduce the thickness of gravel bedding, and make the road slope steeper, reduce the amount of construction earthwork, less land occupation. China's railway department in 1981 began to apply geotextile to deal with roadbed slurry damage polypropylene geotextile for water conservancy project construction.
