Barrier geosynthetic liners, or geomembranes, provide a protective layer in landfill, agricultural and industrial sites. The goal is to keep chemicals such as VOCs (volatile organic compounds) and greenhouse gases from diffusing out of stored materials and contaminate the surrounding environment. Adding EVALâ„¢ barrier performance to existing geomembrane designs greatly improves the performance of geomembranes to better protect soil, water and air quality. A cost-effective alternative to expensive remediation of contaminated sites. + Protecting the environment + EVAL barrier against VOCs + EVAL barrier against hydrocarbon VOCs + EVAL barrier against greenhouse gases

Floor heating systems made of heating pipes of polybutene (PB), polypropylene (PP) or cross-linked polyethylene (PEX) can cause potential corrosion of the metal parts in the heating element due to the oxygen that easily permeates through the plastic pipes and into the heating circuit. To avoid this corrosion several options can be taken: using corrosion resistant material adding rust-preventive agents into the water reducing the oxygen permeability of the pipe. Reducing the oxygen permeability of the pipes is the most secure and economical solution. By using a multilayer pipe made of plastic containing an EVALâ„¢ barrier layer, the oxygen transmission rate will be reduced to a minimum and the corrosion of the metal parts in the heating system is minimised. The gas barrier property of the EVALâ„¢ resins prevents oxygen from permeating through the wall of the pipe and subsequently dissolving into the circulating hot water, thereby corroding metal parts in the heating element.
