Floating covers manufactured from geomembranes are a popular solution to odor containment and are an integral component of low rate anaerobic digestion systems. SIGMA® offers many features unmatched for this application. SIGMA has superior seam strength under elevated temperature constant loading, essential to personnel that must walk on the floating covers. SIGMA low thermal expansion-contraction properties make operation and maintenance simple. The broad range of chemical resistance and flexible nature of the membrane make it the ideal material for floating cover construction.
