一、Material Description：

The permeable fabric material is a permeable fabric woven from a single fiber with anti-ultraviolet, anti-static, and anti-freeze treatment. The main component of the fiber is polypropylene, which has high tensile strength, high tearing degree and excellent elongation. , The thickness and width of the fibers should be uniform, the weaving is tight, the gaps are uniform, and the woven fabric has good water permeability and acid and alkali resistance.

二、Product Features：

(1) The use of permeable woven fabric can be used for bridges, slopes, seawalls, railways, pulped highways and temporary access roads for construction of various projects. Reduce uneven subsidence and erosion of construction foundation stones, prevent soil erosion, and collapse to facilitate construction.

　　(2) The properties of permeable fabric include:

       isolation, drainage,filtration, and reinforcement.

       (3) The direction of the isolation function can stabilize the

        particle structure of each layer of materials and prevent them

        from being mixed on various materials. In the isolation of road

        construction, the particle structure of each layer of material can

        be stable and not mixed.

(4) Drainage and filtration functions. The permeable fabric is usually placed between the soil and the permeable material, so that the water can be removed. The permeable material is often piled stones, permeable water pipes or porous permeable plastic blankets. Its main function is to collect and conduct water. The function of permeable fabric is to allow water to pass through, while preventing soil from moving fine particles. With regard to the filter layer for slope protection, the movement of soil fine particles.

四、Product construction instructions：

Before the permeable fabric is laid, the ground or side slope shall be leveled, and its laying direction shall be laid in strips across the centerline of the ridge (vertical). When there is a protective layer of soil or stone above the permeable fabric, in order to prevent the permeable fabric from sliding on the slope, it is necessary to install anchor ditches. Alternatively, sandbags can be used to hold down the permeable fabric before covering the soil or before anchoring. The two ends should be overlapped by more than 30 cm if they are overlapped naturally. If they are overlapped by a sewing machine, the two ends should be overlapped by more than 5 cm. In construction, the woven filter material will not be wrinkled. The material placed on the permeable fabric should be such that the ground fabric is under even pressure and in close contact with the soil.

       Slope remediation, Marine engineering,Landscape engineering,

       Water conservancy project will be widely used.
