Description

Introduction

Geotextiles, also known as geofabrics, are essential materials in modern engineering projects, particularly in civil engineering and land reclamation. They are textiles that are designed to withstand the forces of nature and the demands of human activity, while also being environmentally friendly.

Geotextiles have a wide range of applications, including road construction, dams and levees, riverbank protection, and erosion control. They are used to separate and stabilize layers of soil, prevent erosion, and improve the strength and durability of structures.

Applications

1. QuarantineUse geotextiles to isolate (soil and sand, soil and concrete, etc.). So that two or more materials do not lose, not mixed.
2. Filtration (reverse filtration)When the water flows from the fine soil layer to the coarse soil layer, the good air permeability and water permeability of the geotextile are used to make the water flow through, and effectively intercept the soil particles, fine sand, small stone, etc., in order to maintain the stability of the water and soil engineering.
3. Drainage
Geotextile has good water conduction performance, it can form a drainage channel inside the soil body, and the excess liquid and gas in the soil structure are discharged.4: 4. Reinforcement
The use of geotextile to enhance the tensile strength and deformation resistance of soil, enhance the stability of building structure, and improve the quality of soil.
