Exemplifying with Filament Spunbond Nonwovens Geotextile:
Specifications of Filament Spunbond Nonwovens Geotextile (GB/T 17639-2008)

Engineered with superior water permeability, exceptional filtration capabilities, outstanding durability, and remarkable adaptability to deformation, our Robust Polypropylene Nonwoven Fabric also boasts excellent plane drainage abilities. Perfectly suited for advanced geotextile filtration solutions, it consistently delivers top-tier performance.

Functions include advanced filtration, robust reinforcement, efficient drainage, reliable separation, comprehensive protection, and long-lasting stabilization.
(1) Essential for reinforcing backfills in retaining walls or anchoring their panels, ideal for constructing wraparound retaining walls or abutments.
(2) Enhances the durability of flexible pavements, efficiently repairs road cracks, and effectively prevents reflective cracking on pavements.
(3) Significantly improves the stability of gravel slopes and reinforced soil, offering exceptional protection against soil erosion and freezing damage in low temperatures.
(4) Serves as an excellent isolation layer between road ballast and roadbed or between the road surface and soft foundations.
(5) Perfect for isolating artificial earth fills, rockfills, or material fields from their foundations, and for separating different frozen soil layers. Provides superb backfiltration and reinforcement.
(6) Acts as a critical filter layer for the initial upstream dam surfaces of ash or tailings dams, and serves as a dependable filter layer in drainage systems within retaining wall backfills.
(7) Optimal for creating filter layers around drainage dark pipes or gravel drainage dark ditches, ensuring efficient water management.
(8) Integral to filter layers for water wells, relief wells, or baroclinic pipes in water conservancy projects, ensuring superior filtration and drainage.
(9) Offers an effective isolation layer between geotextiles and roads, airports, railway tracks, and artificial rockfills, enhancing foundation stability.
(10) Facilitates vertical or horizontal drainage in earth dams, effectively dissipating void water pressure when buried in the soil.
(11) Provides reliable drainage behind impermeable geomembranes or beneath concrete protection in earth dams or embankments, preventing water accumulation.
(12) Eliminates water seepage around tunnels, significantly reducing external water pressure on linings and preventing seepage around buildings.
(13) Ensures efficient drainage for artificial land foundations and sports ground foundations, maintaining structural integrity.
(14) Reinforces weak foundations in projects involving roads (including temporary roads), railways, embankments, earth-rock dams, airports, and sports grounds, enhancing project durability.
