Introduction
As environmental regulations become increasingly stringent, geomembranes have emerged as the critical component in modern impermeable engineering. This case study examines the performance of HDPE geomembrane (1.5mm smooth surface) in a [Province] Municipal Landfill Project, demonstrating replicable technical solutions for the industry.

- Project Background
Key Data:
Local EPA 202X reports classified this landfill’s leachate pollution risk as Level III
Required high-performance geomembrane meeting ASTM GM13 standards
Selected product: Yurun’s HDPE Geomembrane with verified specifications:
Tensile Strength: ≥25kN/m
Puncture Resistance: ≥500N
Permeability Coefficient: ≤1×10⁻¹³ cm/s
- Critical Installation Technologies
Geomembrane Construction Best Practices:
- Subgrade Preparation
Deployed **600g/m² nonwoven geotextile** as protective layer
Ensured zero damage to the impermeable geomembrane liner
2.Welding Process
Dual-track hot wedge welding** at 280±10℃
All seams passed **air channel testing** (0.2MPa/5min pressure hold)
3.Anchoring System
Stainless steel batten bars + chemical anchors
So lved cracking issues from conventional concrete anchoring
- Quality Verification Data
|Test Parameter|Standard Requirement|Actual Result|
|Peel Strength (Welds)|≥15N/mm|18.3N/mm|
|Hydrostatic Resistance|≥0.6MPa| 0.82MPa|
|UV Aging Strength Retention|≥80%|89.7%|
- Project Achievements
Leachate collection efficiency:99.6% (Exceeding GB16889-2008 standards)
40% faster installation** vs traditional clay liners
Client testimonial: “Though reinforced geomembrane cost was higher upfront, it reduced long-term maintenance expenses by 60%.”
5 Industry Recommendations
Preferred applications for textured geomembrane:
Slope protection (>1:3 gradient)
Tailings ponds requiring geomembrane-geotextile composites
