Crescent Duck, in coordination with its engineering consultants at Applied Technologies, Inc., contacted Geomembrane Technologies Inc. (GTI) for advice on replacing the damaged cover. As part of its research efforts, Crescent Duck visited another plant that had installed a GTI insulated gas collection cover and saw the quality and durability of the product first-hand. This site visit, combined with price and the trusting relationship with GTI’s knowledgeable staff, led Crescent Duck to choose GTI for its own replacement cover.
The new cover design consists of Seaman Corporation’s 8148 cream-colored XR-5® for biogas collection. The cover is insulated with 2 in (5 cm) of flexible closed-cell polyethylene foam thermally bonded to 40 mil HDPE for reinforcement. The entire replacement took only one week to complete.
