1. Slope Suitability: The textured floor drastically will increase the coefficient of friction (static coefficient of friction usually ≥0.6), making it appropriate for steeply sloped landfills/tailings ponds, stopping slippage of the higher geotextile, drainage layer, or cowl material.
2. Leachate Drainage: The textured floor creates microchannels that assist drain leachate or condensate underneath the liner, lowering hydrostatic strain (preventing bulging).
3. Puncture Resistance: A 60 mil (1.5 mm) thickness resists puncture from sharp particles (such as building waste and ore), and the CBR bursting power can exceed 500N.
4. Tensile Deformation Resistance: The textured floor distributes stress, decreasing the danger of localized tearing at some point of waste settling or basis deformation (elongation at destroy >700%).
Introduction
60 mil HDPE Textured Geomembrane is the gold popular for present day landfill waterproofing systems, offering an all-around overall performance enchancment over traditional sleek videos or thinner merchandise such as 30 Mil Geomembrane Liner.

Key Advantages
Excellent anti-slip properties: The coefficient of friction reaches 0.6-0.8, twice that of clean membranes, making it in particular appropriate for slope engineering.
Dual drainage: The special concave-convex shape concurrently achieves: Leachate drainage (reducing hydrostatic pressure), methane gasoline series (reducing the chance of methane explosions)
Welding reliability: The textured floor will increase weld power by way of 30%.
Material Composition and Manufacturing
The HDPE Textured Geomembrane is manufactured from high-grade polyethylene resin with specialized additives:
Carbon black (2-3%) for UV stabilization
Antioxidants to prevent oxidative degradation
Stabilizers for temperature resistance
The texturing process creates a uniform surface pattern with:
Peak-to-valley top of 0.3-0.8mm
Surface roughness (Ra) of 20-50μm
Pattern density of 40-60 peaks per rectangular inch
Application
Hazardous waste landfills: Withstands extreme pH environments of 2-12
Mine tailings ponds: Resists punctures from sharp objects in the ore
Methane collection systems: Textured surface facing downward optimizes gas conduction
Steep slopes: 3:1 slopes require no additional anchoring
