Northwest Linings has been supplying and installing membrane liners since 1973. In that span of time, we have installed over 120,000,000 square feet of membrane liners and floating covers. Our projects have varied from 20x20 tank liners to 1.5 million sq. ft. floating reservoir covers. Our trained crews have a nucleus of men with over five years of membrane liner experience.
