A HDPE geomembrane smooth is very low permeability synthetic membrane liner or barrier with smooth surface. It can be used solely or with any geotechnical engineering related material so as to control fluid (or gas) migration in a human-made project, structure, or system. 

The manufacturing of HDPE geomembrane smooth begins with the production of the raw materials, which mainly include the HDPE polymer resin, and various additives such as carbon black, antioxidants, anti-aging agent, UV absorber, and other adjuvant. The HDPE resin and additives ratio is 97.5:2.5.

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. Oven aging at 85℃, standard OIT, 55% retained after 90 days, oven aging at 85℃,high pressure OIT, 80% retained after 90 days.

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

The raw materials used HDPE geomembrane have reached relevant international standards, and are non-toxic and environmentally friendly. Widely used in drinking water 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.
