Chlorosulfonated Polyethylene (CSPE), formerly known as Hypalon, is a high-performance geomembrane material designed for long-term applications, including floating covers and exposed liners. As a floating cover material, CSPE provides truly outstanding UV protection and long-term performance. CSPE floating covers are engineered to eliminate evaporation and protect the water source from contaminants, including dirt and debris. CSPE has been used extensively for water containment and protection applications for over 45 years and is backed with an industry-leading 30-year weathering warranty. The use of CSPE floating covers in reservoirs is one of the most economical ways of storing and treating large volumes of water. CSPE geomembranes and floating covers are used worldwide in containment applications to protect water, including municipal water districts, mining, oil and gas, and agriculture.
CSPE materials are available in several styles and colours, with variations in the number of plies, the supporting scrim type, and the overall thickness of the liner. Layfield has extensive global experience supplying and installing CSPE floating covers. Layfield provides design support, fabrication, and installation services. Our floating covers include defined sump and tensioned cable-designed systems ensuring proper cover tensioning, buoyancy, and long-term performance.

Water reservoirs using CSPE floating covers are often up to 70% more cost-effective for applications of storing and treating large quantities of potable water versus above-ground tanks and underground clearwells.
