PRODUCT DESCRIPTION

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 Underliners are constructed of nonwoven needle punched fabrics in various weights. Use of this material under your liner will help protect the inner wall from punctures caused by stones and cushion the pond wall for fish, while allowing gases to escape to maintain the proper biological balance for all pond life.
