1. Mechanical properties
· Breaking strength: longitudinal (MD) and transverse (TD) tensile strength can reach 4.5~35kN/m, and high-weight products can exceed 50kN/m.
· Tear strength: 0.17~1.25kN, suitable for complex geological conditions.
2. Functional indicators
· Permeability coefficient: 0.07~0.2mm pore size, vertical permeability coefficient of 10⁻¹~10⁻³ cm/s, meeting drainage needs.
· Corrosion resistance: acid and alkali resistance, ultraviolet (UV) resistance, microbial erosion resistance, life span up to 50 years.
Application scenarios of polyester woven geotextile
Polyester woven geotextile is widely used in many fields due to its high strength, corrosion resistance and water permeability.
Civil engineering reinforcement and protection
1. Road and railway subgrade reinforcement
· Used to repair cracks in flexible pavements, disperse loads and prevent reflective cracks.
· Provide reinforcement in soft soil foundations or pile cap areas to enhance the bearing capacity of the subgrade.
2. Slope and dam protection
· Anti-scouring and erosion protection of river embankments and reservoir slopes to resist water flow impact.
· As a reinforcement material in retaining wall backfill to improve structural stability.
Drainage and filtration system
1. Soil drainage layer
· Separate sand and clay to prevent blockage, suitable for roadbed, tunnel and other projects.
· As a drainage layer around the tunnel, it reduces the lining pressure.
2. Drainage in special scenarios
· Liquid drainage in mines and landfills to avoid environmental pollution.
· Drainage and anti-filtration in reclamation and coastal tidal flat projects.
Environmental protection and ecological engineering
1. Ecological slope protection and greening
·Support vegetation growth, used for artificial slope protection and ecological restoration, with drainage and soil protection functions.
·Prevent soil erosion, suitable for steep slopes and erosion-prone areas.
2. Groundwater control
·Regulate soil moisture to prevent freezing damage and liquefaction risks.
