Textured Geomembranes

Textured geomembrane enhances friction coefficient to 0.6-0.8 via surface roughening (sprayed/Columnar), improving anti-slip performance by over 50% for steep slopes and vertical anti-seepage applications. Made of HDPE, it exhibits exceptional chemical stability, resisting pH 1-14 acids/alkalis and 80℃ high temperatures, with permeability ≤1×10⁻¹³ cm/s meeting international anti-seepage standards. UV-resistant formulation ensures 50+ year service life across -60℃ to +60℃ extremes. Dual-track thermal welding achieves ≥95% joint strength retention, guaranteeing long-term structural integrity

Key Applications

• A. Environmental Engineering
• •Landfill slope stabilization (textured surface facing soil)
• •Hazardous waste containment (sandwiched texture for double protection)
• •Wastewater treatment ponds (columnar points enhance drainage)

• B. Hydraulic Infrastructure
• •Reservoir/dam anti-seepage (vertical core walls with textured layers)
• •Canal lining (prevents water infiltration in irrigation systems)
• •Riverbank reinforcement (prevents erosion in flood-prone areas)

• C. Mining Operations
• •Tailings pond lining (columnar texture controls leachate flow)
• •Heap leach pad (textured surface prevents acid solution penetration)
• •Solution ponds (withstands 80℃ chemical solutions) 

• D. Aquaculture & Agriculture
• •Fish pond liners (prevents water leakage in intensive farming)
• •Seaweed cultivation ponds (anti-algae adhesive texture)
• •Irrigation channels (reduces water loss by 40-60%)
