Features
1)High anti-seepage ratio:
HDPE geomembrane has a great anti-seepage effect unmatched by ordinary waterproof materials, and is recommended in some projects with high anti-seepage requirements.It's Permeability property is ≤1.0*10-13g●cm/(cm2●s●pa).
2)Chemical Stability:
It has excellent stability, acid and alkali resistance, salt solution, oil, alcohol, etc., and is mostly used in sewage treatment and landfills.
3)Anti plant root system
HDPE geomembrane has excellent puncture resistance and resists most plant roots. It is a must-choice product for planting roofs.
4)Aging resistance
HDPE geomembrane has excellent anti-aging, anti-ultraviolet, anti-decomposition capabilities.
5)High Mechanic strength
It has good mechanical strength, and is first choice for seepage prevention in water conservancy projects. The tensile strength ,tear resistance, and puncture resistance properties all meet GRI-GM13 standard.
6)Low cost
Compared with other traditional materials, HDPE geomembrane has obvious cost advantages and is the best product for water storage and anti-seepage.
7)Environmental protection formulation
HDPE raw Materials are imported raw material , in line with relevant international standards . widely used in drinking ponds , breeding ponds, etc .
8)Rapid construction
Compared with other traditional materials, HDPE geomembrane can be laid in a variety of forms to meet different construction requirements.
Application
1.Landfill lining
To protect the ground water from contamination
2.Landfill capping
To prevent fluid flow in the landfill , to trap the properly vent the fases generated during decomposition of organic wasr and to permit effcient revegetation and restoration of the area
3.Warer conservancy Project
Anti-seepage of the oil tank in chemical plant , refinery plant , petrol station , chemical reaction camera, inner liner of settling tank , secondary liner etc .
4.Construction Project
Underground project of subway and buliding , roof reservoir , roof garder , sewage pipeline etc .
5.Aquaculture
Inner liner or fish pind , shrimp pond , revetment of sea cucumber pool etc
6.Agriculture
Reservoir , drinking water pool , pool irrigation system
7.Salt Industry
Salt filed crystallizing pond , brine pond , salt film etc .
Warranty
1 Upon request of the purchaser in the contract or order , geomembrane warrant of the quality of the material must be furnished at the completion of the terms of the contract .
2 Recommended quality assurance for the production and testing of smooth HDPE geomembranes in accordance with the GM13 Standard can be found in appendix a of the GM 13 standard .
Appearance
Smooth geomembrane shall have good appearance qualities . It shall be free from such defects that would affect the specified properties of the geomembrane
