The rough-textured geotextile is a geotechnical material made by blowing a film and extruding three layers together using high-density polyethylene resin particles as the raw material. It is composed of approximately 97.5% high-quality polyethylene, 2.5% carbon black, trace amounts of antioxidants and heat stabilizers. Its types include single-rough-textured geotextile, double-rough-textured geotextile, and column-point geotextile. 

Single rough-faced geotextile membrane: One side is rough and the other is smooth. In the construction of slope seepage prevention projects, the rough side is usually facing upwards and in contact with the geotextile fabric, providing a slip-resistant effect.

Double rough-faced geotextile membrane: Both sides have rough surfaces. It has a wide range of applications. In the construction of slope seepage prevention projects, it can be in contact with the geotextile fabric, providing a slip-resistant effect.

Column-point geotextile membrane: One or both sides have uniform protrusions. The rough points are evenly distributed and aesthetically pleasing. It can be applied in slope seepage prevention projects, achieving the effects of seepage prevention, slip resistance, and anti-pollution. Characteristics

Increase friction coefficient: The small particles or protrusions on the surface increase the friction coefficient, enhancing the stability of the slope, allowing the usable volume that the smooth HDPE geotextile can bear to reach its maximum, which is more beneficial for steep slopes and vertical waterproofing, and improving the engineering stability. For example, in steep canyon-type and landfill sites with high waste ( > 100m), using double roughened geotextiles has good stability.
High seepage coefficient: It has a permeability coefficient that is incomparable to ordinary waterproof materials, generally K < 1.0×10⁻¹³g·cm/(cm²·s·Pa).
Good chemical stability: It has excellent chemical stability, widely used in sewage treatment, chemical reaction tanks, landfill sites, etc., resistant to high temperatures, asphalt, acids, alkalis, and more than 80 kinds of strong acid and strong alkali chemical media corrosion.
Excellent aging resistance: It has excellent anti-aging, anti-ultraviolet, and anti-decomposition capabilities, can be used exposed, and the material service life can reach 50 - 70 years.
Resistant to plant roots: It has excellent anti-penetration performance, can resist most plant roots.
