Liners, sealing membranes for steel tanks, reservoirs, basins, lagoons and ponds

We deliver our liners and sealing membranes over the whole world at a very good price!

We are suppliers of the highest quality liners, waterproofing membranes for sealing tanks, storage silos and retention reservoirs for clean water and contaminated with chemical compounds.
We export these highest quality liners over the whole world!
Standard materials such as PVC, FPP, LDPE and EPDM are commonly used. Currently, after years of research, we can provide you with a new type of waterproofing liner – much more flexible, more durable and more resistant to external factors and any mechanical damage.
– DELAFLEX® can be used in all types and types of tanks
– DELAFLEX® waterproofing membranes for retention tanks are delivered in all (also very large) sizes.
– DELAFLEX® floor coverings are available in two thicknesses – 0.6 mm and 1.0 mm
– DELAFLEX® is welded in accordance with the guidelines of KIWA BRL-K 537.
We also deliver and assemble in indicated place complete steel tanks, silos, waterproofing materials, anti-limescale covers and steel cover.
In our tanks, reservoirs and silos we use following liners (sealing membranes) including:
  • DelaFlex 0,6mm and 1 mm thick – for all types and kinds of tanks for water, drinking water or liquid pollutants such as sewage, slurry, liquid manure. For DelaFlex material, we provide a 15-year warranty on factory-made welds as well as the material’s resistance to UV radiation.
  • PCV KIWA –ATA 0,5mm – for drinking water storage.
  • PVC Tropic 1mm – for clean water storage in temperate climate.
  • ASTRIN 0,5mm oraz 1mm – for clean water and waste water storage (drainage water, sewage).
  • EPDM 1 mm – for clean water and slightly contaminated water storage in cold and hot climate
  • HDPE, HDPE T-lining, LDPE, PVC Re-lining, Polyester with PVC protection.

HDPE 1.5 mm – Physical characteristic

DL-HDPE is a black, high quality, high density polyethylene (HDPE) geomembrane produced form specially formulated, virgin polyethylene resin. The polyethylene resin is designed specifically for flexible and durable geomembrane applications. DL-HDPE contains approximately 97.5% polyethylene, 2.5% carbon black and trace amounts of antioxidants and heat stabilizers. DL-HDPE has outstanding chemical resistance, mechanical properties, environmental stress crack resistance, dimensional stability and thermal aging characteristics. DL-HDPE has excellent resistance to UV radiation and is suitable for exposed applications. These product specifications (> 1.5 mm) meet or exceed GRI-GM 13.
