Geotextile products: geotextile geotextile with polyester or polypropylene long fiber as raw material, the formation of After combing, acupuncture, heat-setting process processing products of different specifications. Specifications geotextile mass per unit area of ??100g/m2- 1000g/m2 the maximum width ≤ 4. 5m, within this range can be based on user requirements, the use of different raw materials, the production of a particular specification products in accordance with the design standards organization. Geotextile with high tensile strength, good permeability, high temperature resistant, anti-freezing, anti-aging, corrosion resistance and other features, functions and applications in engineering applications can play a role of filtration, drainage, reinforcement, is widely used in water conservancy , electricity, ports, airports, roads, railways, environmental protection and other construction projects. The connection method lap: lap width and basic conditions, it is recommended that for the flat ground, overlap width 20cm and lap width 30cm length direction of the foundation is uneven or soft soil lots. Stitched: To save material than the lap, the amount of overlap is generally about 5cm.
