Separation means using geotextiles to separate building materials (such as soil and sand, sand and gravel, soil and concrete, etc.) with different physical properties (large grain size, distribution, consistency and density, etc.). The two kinds of materials are not lost or mixed, the overall structure and function of the materials are maintained, and the load bearing capacity of the structure is strengthened.

Filtration When water flows from the fine soil layer into the coarse soil layer, the good air permeability and water permeability of the needle-punched geotextile are used to allow the water to pass through, and the soil particles, fine sand, small stones, etc. can be effectively intercepted to maintain the water and soil The stability of the project.

Drainage Needle-punched geotextile is a good water-conducting material. It can form a drainage channel inside the soil and drain the excess liquid and gas from the soil structure.

Reinforcement the use of needle-punched geotextiles to enhance the tensile strength and deformation resistance of the soil, increase the stability of the building structure, and improve the quality of the soil.

Protection Effectively diffuse, transfer or decompose the concentrated stress to prevent the figure body from being damaged by external forces.

Waterproof needle-punched geotextile is combined with other materials (mainly asphalt or plastic film) to form an impermeable barrier in the soil layer. (Used for road resurfacing and repairing, etc.)
