Barriers


In environmental and civil applications in many cases a need to block a waterflow is faced, in order to avoid groundwater spreading of pollutants or be able to create a so called polder construction.

Cofra has various barrier solutions available. Some of these make use of HDPE membranes, resistant to a wide range of chemicals. Other are based on cement bentonite walls installed with a trencher. Sometimes we combine these techniques. Our barriers can be installed horizontal, on a slope or even vertical over 30 meters of depth. Cofra solutions focus on separation, not on structural strength.
