Weldable HDPE Geomembrane with Ultra-Low Permeability and Excellent UV Resistance for Mine Water Storage

Product Description

Weldable HDPE Geomembrane for Mine Water Storage

Our Weldable HDPE Geomembrane is a high-performance water storage material engineered specifically for mine water storage applications. Manufactured from high-purity HDPE resin with consistent density and uniform molecular weight distribution through precision extrusion processes, this geomembrane delivers exceptional performance in demanding mining environments.

Key Features and Benefits

Superior Weldability: Seamlessly welded using HDPE welding equipment to create large-area water storage structures with exceptional structural integrity and leak-free performance
Ultra-Low Permeability: Extremely low permeability coefficient (≤1.0×10⁻¹³ cm/s) minimizes water loss through evaporation and seepage
Excellent Mechanical Properties: High tensile strength (≥25MPa) and elongation at break (≥450%) accommodate ground settlement without cracking
Outstanding Durability: UV stabilizers and anti-aging agents provide long-term weather resistance and chemical protection against mineral water erosion

Product Specifications

Thickness Range	0.8mm to 2.5mm
Width Range	2m to 8m (customizable)
Tensile Strength	≥25MPa
Elongation at Break	≥450%
Permeability Coefficient	≤1.0×10⁻¹³ cm/s

Application Scenarios

This geomembrane is specifically designed for various mine water storage applications:

Mine reservoirs for surface water and groundwater storage
Water tanks for domestic and production water supply
Irrigation ponds for mining area vegetation
Emergency water storage pits for water shortage situations
Temporary water storage facilities during mine construction
Renovation projects for existing mine water storage facilities

Installation Guidelines

Proper installation is crucial for optimal performance and longevity:

Prepare a flat, compacted base surface before installation
Use non-woven geotextile as protective underlayment to prevent punctures
Install from bottom to top of the facility using HDPE welding equipment
Ensure straight, firm welding seams for leak-proof joints
Secure top edges with anchor grooves to withstand water pressure
Conduct water filling tests (24-48 hours observation) to verify integrity
Avoid exceeding design capacity to prevent excessive pressure damage
Perform regular inspections and timely repairs of any surface damage
