200g 300g pp nonwoven geotextile improves soil reinforcement in road construction

PP nonwoven geotextile is a non-woven fabric material made of polypropylene (PP) as the main raw material through spunbonding or needle punching. It is widely used in geotechnical engineering due to its excellent performance and wide applicability, especially in the fields of isolation, reinforcement, filtration and drainage.

Characteristics of PP nonwoven geotextile；

High strength and durability; PP nonwoven geotextile is made of polypropylene raw material, with high tensile strength and tear resistance to withstand various external forces, and excellent durability.

Excellent chemical stability; PP nonwoven geotextile has good tolerance to acids, alkalis, salts and most chemicals, and is suitable for use in complex geological environments.

Good water permeability; non-woven structure has good water permeability, which can effectively prevent water flow blockage and is suitable for drainage and filtration functions.

Light weight and easy construction; PP non-woven geotextile has low density and light weight, is easy to transport and lay, and can significantly reduce construction costs.

Excellent environmental protection performance; polypropylene material is non-toxic and harmless, meets environmental protection requirements, and can be used in ecological engineering.

Main uses of PP nonwoven geotextiles;

1. Isolation function; Separate different material layers, such as in road or railway projects, to prevent mud and gravel from mixing and maintain the stability of the roadbed structure.
2. Reinforcement function; In reinforcement projects such as slopes and dams, the overall stability of the structure is improved by enhancing the tensile strength of the soil.
3. Filtration function; Water conservancy projects or drainage systems prevent the loss of soil particles while ensuring the free flow of water.
4. Drainage function; Underground drainage systems remove excess water through good permeability to prevent water accumulation.
5. Protection function; Protect structures from external erosion in projects such as landfills and dams. Main uses of PP non-woven geotextiles

Application cases of PP nonwoven geotextiles;

1. Road and railway projects; laying PP nonwoven geotextiles in the roadbed can enhance the bearing capacity and extend the life of the road.
2. Water conservancy projects; river and lake slope protection projects to prevent soil erosion.
3. Landfills; anti-seepage layers and protective layers of drainage systems to improve the overall environmental performance of the project.
4. Landscaping; in greening projects, it is used to prevent weed growth while ensuring the air permeability and drainage of the soil.
5. Tunnel and underground projects; anti-seepage drainage layers to protect tunnels and underground structures from water damage.
