Geotextile tubes are made by PP woven fabric in a variety of sizes and lengths. They are in extra wide sizes with greater load distribution to resist punching and protect the embankment and foundation. Geotextile tubes are not only used to form shoreline structure including form temporary breakwaters, headlands, revetment on sand beach.
Geotextile Tube is one of the most effective components that are most usually used in protective structure of waterproof erosion. Soft mattress is covered to the places where water flows to reduce the impact energy of water flow and protect soil particles from being flown away by water flow by means of its filtration function, thus, ensuring the stability of soil mass.
installation steps
1.: The first step is to fill, high strength and permeable geotextile bag body needed to make into actual, then filling slurry into the bag.
2. The second step is drainage, because the geotextile that makes up the bag has tiny holes that trap it in the mud, solids can also discharge water from the mud, which can effectively reduce the volume of inclusion in the bag body,The bag body can be repeatedly filled until the allowable height of the bag material is reached, and the discharged water can be reused.
3.The third step is consolidation. After repeated filling and drainage, the fine particles left in the bag body will gradually consolidate due to drying.
