Haoyang’s Advanced Solutions

Haoyang’s HDPE landfill liner system provides a five-layer anti-seepage solution for hazardous waste disposal. Combining UV-resistant HDPE, bentonite blankets, geotextiles, and three-dimensional drainage mesh, our system guarantees zero leakage, environmental protection, and efficient resource recovery.

Hazardous Waste Landfill HDPE Liner System

1.Five-Layer Anti-Seepage System for Landfills

Layer Material Technical Specifications Core Function
Protective Layer Staple-Fiber Needle-Punched Geotextile CBR Bursting Strength ≥ 3.5kN Puncture-resistant buffer
Primary anti-seepage layer 2.0mm HDPE geomembrane Elongation at break ≥ 700% (GB/T 17643) Main Anti-seepage Layer
Secondary anti-seepage layer 4000g/m2 sodium-based bentonite waterproofing blanket Expansion index ≥ 24ml/2g (J/T 1351) Self-repairing micro-leakage
Drainage layer

 

 three-dimensional composite drainage mesh hydraulic conductivity ≥ 3.0×m²/s leachate drainage

 
Base layer Compacted clay (permeability coefficient <cm/s) moisture content ≤ 20% Final barrier

2.Key Features & Advantages 

  • Five-layer structure: Protective geotextile, primary HDPE liner, bentonite blanket, drainage mesh, compacted clay base

  • UV-resistant HDPE: Long-term durability in harsh environments

  • Bentonite waterproofing: Self-healing micro-leakage prevention

  • Geotextiles & drainage: Puncture resistance and leachate management

  • Sustainability: Supports hazardous waste stabilization and resource recovery

  • Testing: CNAS labs check stress cracking, ash content for reliability.

Benchmark Project Demonstration

1.Yulin Mahuangliang Industrial Solid Waste Project:

Processes tons of waste annually, including chemical residues.

Five-layer system with recovery and stabilization prevents leaks.

Five years below standards, no leaks, boosting benefits.

2.Zibo Linzi Fly Ash Landfill Project:

Upgraded to 2.5mm HDPE for heavy metals and pH issues.

X-ray inspection, passed 72-hour test, protecting soil and water.

Achievements:

  • Environmental: Prevents leaks, protects soil and water.
  • Resource: Enhances utilization, cuts costs.
  • Economic: Reduces fines and land costs, boosts competitiveness.
  • Social: Builds eco-image, promotes local growth.

High-speed railway project
Ballastless track sliding layer: used in the sliding layer of high speed rail track structure (two cloths and one membrane structure), located between the roadbed slab and bridge deck, requires strong alkali resistance to cope with the alkaline environment of concrete. Isolation layer: preventing mixing between roadbed and track structure, ensuring track stability.
Roadbed reinforcement for road and railroad construction
Enhance the bearing capacity of weak foundation, reduce uneven settlement, applied to highway, railroad roadbed and airport runway. Isolation and protection: isolate ballast and roadbed, prevent reflection cracks and frost damage, prolong the service life of road surface.
water conservancy engineering dike and river channel reinforcement
Used for seepage control and reinforcement of reservoirs, dykes and rivers to enhance structural stability. Drainage and filtration: used as filter layer in earth and stone dams and drainage systems to prevent soil erosion and maintain water permeability.
