400g 100% PP Non Woven Geotextile For Soft Soil And Road Base Strengthening

400g Polypropylene Non Woven Geotextile for Strengthening of soft soil and road base

Staple fiber PP nonwoven geotextile is made from 100% high strength polypropylene (PP) short fiber. Its processing way includes short fiber material carding, lapping, needle punching, being cut and rolled. This permeable fabric has the properties to separate, filter, reinforce, protect, or drain.

Application of Polypropylene Non Woven Geotextile

Nonwoven geotextiles have a wide range of applications in civil environmental engineering and construction projects.

· Filtration

When water passes from a fine-grained to a coarse grained layer, Non-woven Geotextiles can retain fine particles well. Such as when water flows from a sandy soil into a Geotextile wrapped gravel drain.

· Separation

To separate two layers of soil with different physical properties, such as the separation of road gravel from soft sub-base materials.

· Drainage

To drain liquid or gas from the plane of the fabric, which leads to draining or venting of the soil, such as the gas vent layer in a landfill cap.

· Reinforcement

To improve the load bearing capacity of a specific soil structure, such as the reinforcement of a retaining wall

GEOTEXTILE INSTALLATION

To pave by roll with artifical method, the fabric must be level and appropriately leave the margins for deformation. The inst lation method usually has overlapping, sewing and welding. The overlapping part is generally more than O.2m. It should be welded or stitched for the exposed geotextiles. AII sewing must be continuously carried out(for example, point-sewing is not allowed), the geotextiles must be overlapped more than 200mm before overlapping. The minimum distance between sewing needle and the fabric edge(the edge of exposed material) is at least 25mm.
