Application

1. Water conservancy projects: Anti-seepage, landslide prevention and erosion resistance of rivers, dams, reservoirs, etc. in water conservancy projects.

2. Foundation initiatives: Techniques for soil reinforcement, seepage prevention, and soil conservation aimed at enhancing the stability and dependability of foundation initiatives.

3. Road projects: reinforcement and stabilization of roadbeds to reduce the occurrence of road cracks and settlements and extend the service life of roads.

4. Mining and landfill management: Holistic oversight of mining operations, along with reinforcement and seepage prevention in landfills to mitigate soil and groundwater contamination.

5. Agricultural initiatives: Strategies for wind protection and thermal insulation, moisture retention in soil, and overall soil management to foster crop development and boost yields.

Features:

1. Exceptional strength and durability
Made from continuous polyester filament, it exhibits high tensile strength, minimal elongation, and slight deformation under prolonged load. It is resistant to acids and alkalis, as well as UV aging.

2. Superior permeability and filtration capabilities
The three-dimensional pore structure guarantees effective water permeability while efficiently capturing soil particles during drainage.

It serves as a filter layer, replacing conventional sand and gravel, thereby streamlining the construction process.

3. Isolation and reinforcement
It prevents the intermingling of different soil layers or fillers, ensuring structural stability. When combined with the soil, it distributes stress, enhances the load-bearing capacity of the foundation, and minimizes settlement.

4. Environmental sustainability and adaptability
The materials used are recyclable, the manufacturing process is energy-efficient, and it complies with green engineering standards.

5. Ease of construction
The roll is lightweight and offers high laying efficiency. It can be cut on-site, with overlaps stitched or thermally bonded to reduce construction time.
