Geotextiles Advantages 1. Isolation The use of geotextile different physical properties (particle size, distribution, density and thickness, etc.) materials (such as soil and sand and gravel soil, soil and concrete, etc.) for isolation. So that two or more materials are not loss of inter-and non hybrid,to maintain the overall structure of the material and functions of the structures is to strengthen the load bearing capacity. 2 Filter When the water from fine materials into the soil layers of rough material, the use of acupuncture geogextile good air and water permeability, so that the water flow through, and effective interception soil particles, spinning, the small stone so as to maintain the stability of the soil and water projects. 3 Drainage Acupuncture geotextile is a good hydraulic material, which can from a soil internal drainage channel, soil structure and excess liquid gasemissions. 4 Reinforced Acupuncture use of geotextile to enhance soil and the tensile strength of the antideformation ability to increase the stability of the building structure in order to improve the quality of the soil. 5 Protection Will focus on effective stress-proliferation, transfer or broken down by external force to prevent the soil and damage.
