Dingkun New Material Co., Ltd. produce geomembrane thickness 0.1-3.0mm, width and length can be customized. HDPE geomembrane is a good anti-seepage geosynthetic material. 

It is a waterproof barrier material produced from high-density polyethylene resin. It has good water permeability, corrosion resistance, anti-aging and strong corrosion resistance.

Dingkun HDPE anti-seepage geomembrane has complete specifications and is widely used.

Today we come to learn about geomembranes used in biogas digesters.

The biogas digester generally adopts HDPE geomembrane with 

a thickness of 1.5mm, and the cover film adopts HDPE geomembrane with a thickness of 2.0mm ASTM GM 13 standard.

Features of geomembrane biogas digesters:

1. Low engineering cost.

2. Easy installation and construction.

3. Excellent chemical resistance.

Construction technology of biogas tank impermeable membrane:

Leveling, Pre-buried pipelines, Bottom film laying, Bottom detection, Top film laying, Backfilling.
