Geotextile Cloth
1.High-Efficiency Filtration & Drainage
Permeable to water but impervious to soil, effectively separating soil layers while facilitating drainage and preventing clogging.
Reduces underground hydrostatic pressure, enhancing foundation stability.
2.Reinforcement & Protection
High tensile strength distributes loads, improving load-bearing capacity of soft foundations, slopes and other structures.
Prevents soil erosion and resists weathering/scouring.
3.Separation & Impermeability
Isolates materials of different particle sizes to prevent intermixing and loss.
4.Easy & Cost-Effective Installation
Lightweight roll material enables simple manual installation, reducing equipment costs.
Product Introduction:
Geotextile Cloth is a permeable geosynthetic material made from synthetic fibers (such as polyester PET or polypropylene PP) through needle-punching, weaving, or thermal bonding processes. Widely used in civil engineering, environmental engineering, and infrastructure construction, it provides functions including reinforcement, separation, filtration, drainage, and protection.
Main Characteristics
1.Physical Properties: Tensile strength, tear strength, burst strength, etc.
2.Hydraulic Properties: Permeability coefficient, porosity (affects drainage and filtration efficiency).
3.Durability: UV resistance, chemical resistance (to acids/alkalis), aging resistance (depends on raw materials and additives).
4.Elongation: Ability to accommodate ground deformation.
