HDPE geomembrane liner is resistant to many different solvents and are the most widely used geomembrane liner in the world. It provides higher specific strength and can withstand higher temperatures. Its exceptional chemical and ultraviolet resistance properties make it an extremely cost-effective product.
High density polyethylene geomembranes HDPE are used as a waterproof barrier for all types of hydraulic work like water reservoirs for agriculture, canals, treatment plants, settling ponds, evaporation ponds, farms, golf courses etc
This type of polyethylene geomembranes are used in projects related to the environment as a barrier to contain liquid or solid contaminants such as waste landfills, leachate, slurry, mining waste, protection against leaks in petrochemical industries, airports, harbours, etc
They are used as well in civil engineering in railway constructions, roads, walls, tunnels, pavements, etc.

Technical Notes
HDPE is a very technical product to work with. It must be installed by certified welding technicians using specialized welding equipment to ensure performance.
Installations are temperature and poor weather sensitive.
40 mil HDPE liner requires extra effort to ensure that the subgrade is in excellent condition. It is suitable as an upgrade from products like the 20 mil RPE for larger installations and is an excellent secondary containment liner on multi-layer systems (for example; subgrade, geotextile layer, 40 mil
HDPE layer, drainage net layer, 60 mil HDPE layer, geotextile layer, fill.)
60 mil HDPE liner is the staple of the industry and is suitable for most applications.
80 mil HDPE liner is a thicker design for more aggressive subgrades.
Recommend Thickness for different civil engainnering

3, Landscape (including artificial lake, river, slop protection, greening waterproof etc.) normally use 0.5mm~1.0mm
4, Water conservancy ( including dam anti-seepage, strengthen etc.)
normally use 0.75mm~1.5mm
5, Roof anti-seepage ( roof planting, roof waterproof, roof garden waterproof etc.)
normally use 0.5mm~1.0mm
6, Underground anti-seepage ( including traffic, subway and roadway’s foundation strengthen, workshop waterproof)
normally use 0.5mm~1.0mm
7, Environmental protection (including landfill, sewage treatment work, power regulating reservoir, industrial and hospital solid waste)
normally use 1.0mm~2.0mm
8, Mining (including Washing tank, ash yard, dissolution tank, sedimentation tank, bottom anti-seepage of tailings etc.)
normally use 1.0mm~2.0mm
