What it is
HDPE membrane is resistant to a large number of chemicals, including acids, salts, alkalis, alcohol, oils and hydrocarbons that occur in practice. The HDPE installed by Cofra complies with the requirements summarized in the BRL-K 538/01. High-Density Poly Ethylene (HDPE) liner consists of a proportion of carbon black, anti-oxidants and stabilizers. It is the most commonly used membrane for the sealing of rubbish tips, dredging tips, lagoons and water reservoirs.
How it works
With the welding of the liner a impermeable seal is created resistance to most chemicals. Monitoring and process control are essential when using HDPE liner for separation purposes. Cofra’s way of working complies with all regulations for HDPE quality control. Our in-house laboratory is equipped to perform all tests required on the liners installed.
Why it's used
HDPE liners are most often used to separate contaminated material from the surrounding areas and block any water flow.
Liners are used in the following markets:
Infrastructure: Liners are used in infrastructure projects to seal contaminated material when used in embankments or to seal excavations from water inflow.
Mining: Liners are used to seal any contaminated material from the environment
Pollution management: Liners are used to seal any contaminated material from the environment
