DeWitt Pond Underliner is a durable, clean, and safe material to install under ponds instead of using cardboard, newspapers, sand, or old carpet padding. DeWitt Pond Underliner is constructed of a nonwoven needle punched 6 oz. fabric. Use of this material under your liner will help protect the inner wall from punctures from stones and cushion the pond wall for fish, while allowing gases to escape to maintain the proper biological balance for all pond life. DeWitt Pond Underliner is easy to use, and installs in minutes.
