HDPE Geomembrane Underground construction Waterproofing Membrane HDPE Pond Liner
Lining of reservoirs with synthetic geomembranes separates the liquid mass from the soil.
The utilization of HDPE Geomembranes for reservoirs lining has been applied in tens of thousands of projects throughout the world and they retain proven cost-benefit advantages.
Please advise what thickness you need, we produce 0.3mm - 3.0mm HDPE Geomembrane
HDPE smooth geomembrane is made from high grade polyethylene raw material,
adding carbon black ,antioxidant, anti-aging and UV resistance component.
It adopted the first class automatic production equipment and three-layer pressing technology.
All products are in accordance with GB/GRI/ASTM GRI 13 standard.
0.5mm or 0.75mm-thickness is used for pond liner
1.5mm-thickness is used for landfill
2.0mm-thickness is used for dam liner
How to extend the service life of geomembrane?
The service life of geomembrane is affected by many factors such as material quality, construction technology, use environment and maintenance measures. The following is a comprehensive strategy to extend its service life:
Raw material selection and production optimization
1. Add anti-aging ingredients
Adding UV inhibitors, antioxidants, light stabilizers and dark carbon black (accounting for 2%-3%) during the production process can significantly delay light-oxidation aging.
High-quality geomembranes use new high-density polyethylene (HDPE) raw materials to avoid shortening the life due to recycled or semi-recycled materials.
2. Control thickness and material
The greater the thickness, the stronger the ability to resist environmental stress cracking. For example, when the thickness of HDPE geomembrane is ≥2.5mm, the underground service life can reach more than 50 years.
Construction process control
1. Base treatment
Remove sharp objects and compact the base. The slope design is recommended to be 1:1.0 to prevent sliding and mechanical damage.
2. Joint welding technology
Use hot melt welding (double-track welding machine) to ensure that the joint strength reaches more than 80% of the parent material to avoid leakage caused by manual bonding.
3. Avoid exposed construction
Cover the protective layer in time after laying (such as non-woven geotextile + silty clay, thickness ≥ 200mm) to reduce direct ultraviolet rays.
Regular maintenance and repair
1. Regular inspection and repair
Check the integrity of joints and covering layers every year, and repair damaged areas in time (such as hot melt patches or adhesives).
2. Covering protective layer
Use rock (particle diameter ≤ 6mm) or deep water to cover to reduce external force and UV damage
