The Science of Surface: Feel the Traction

1. Peaks & Valleys: Nature’s Anchor System

   • Visualize: Dome-shaped studs (1–2mm high) or sand-grain-like dimples pressed or blown into high-density polyethylene (HDPE/LLDPE).

   • Action: When buried under soil or gravel, these textures claw downward, mechanically interlocking with every particle.

   • Result: Imagine a 45° slope during a downpour – the textured liner holds fast while water sheets harmlessly over it.

2. Shear Strength: The Hidden Force Multiplier

   • Picture: Gravel cover sliding against the liner’s surface. On smooth geomembrane, it slips like marbles on ice. On textured?

   • The Grip: Microscopic ridges snag aggregate, transforming sliding force into immobilized mass.

   • Effect: See steep landfill caps or mining slopes – no more liner slippage or cover erosion, even after earthquakes.

Why Texture? Witness the Tenacity:

• Slope Security, Engineered In:
  Visualize a 3:1 dam face. Traditional smooth liners crawl downhill over time, creasing and tearing. Textured geomembrane digs in like crampons on ice – immovable for decades.

• Dual-Sided Armor:
  One side grips subsoil; the reverse bites into gravel cover. Like a tectonic sandwich, locking entire barrier systems in place.

• Firebreak for Liners:
  See stress cracks forming in soil beneath a landfill. Textured surface flexes and absorbs movement without rupture – smooth liners snap like glass.

• Safe Installation, Rain or Shine:
  Workers walk steep slopes in wet conditions. The textured surface grips boots like trail shoes on rock – no dangerous slips.

Performance You Can Measure in Mountains Held Back:

• Friction Angles: Achieves 30–40°+ interface friction – like parking a bulldozer on a sheet-metal roof without sliding.

• Shear Strength: Resists 20+ kN/m² – imagine a loaded dump truck parked sideways on a 1m x 1m patch.

• Puncture Resistance: Dimpled surfaces deflect sharp rocks 50% better than smooth – no weak points.

Where Gravity Meets Its Match:

• Landfill Caps & Base Liners:
  Secures steep final covers against wind uplift and erosion. Base liners grip compacted clay beneath.

• Mining Heap Leach Pads:
  Anchors ore piles on 45° slopes while containing acids.

• Reservoir & Canal Banks:
  Locks to wet subgrades where smooth liners hydroplane.

• Tunnel Waterproofing:
  Clings to curved concrete surfaces without delamination.

• Contaminated Site Caps:
  Defies freeze-thaw cycles that heave smooth liners.

The Unyielding Membrane:

While smooth liners fight gravity, textured geomembrane conquers it. Every dimple, stud, and ridge is a terraformed anchor – friction engineered into every square meter.

Founded in 2008, Jianyi group  is a large production base of solid waste safe landfill and engineering protective materials in China. The company has participated in the major infrastructure construction of the country and the "the Belt and Road", the construction of emergency epidemic prevention projects in Wuhan Huoshen mountain, Leishen mountain and Guangzhou Eighth People's Hospital, the national strategy for special treatment of heavy metals, the landfill and incineration of urban domestic waste, industrial waste, hazardous waste disposal and other environmental protection projects, provided a large number of high-quality new geotechnical environmental protection materials for the partners, and provided overall solutions for the project.
