Pond Underlayment

The Pond Underlayment is highly recommended for every pond installation. This soft, non-woven, needle-punched Geo-textile, polyethylene fabric will last 20+ years under your pond liner. The Pond Underlayment material spreads easily and saves time compared with the old method of newspaper or sand. Pond Underlayment will aid in protecting the pond liner by adding a barrier between the liner and any unseen rocks or other abrasives that may puncture the liner if used alone. It will also help with moisture and gases that can accumulate under the liner. Moisture is absorbed into the Pond Underlayment and wicked up to evaporate out while gases from organic materials are able to be released. Pond Underlayment may also be used on top of the liner when placing larger boulders or sharp rocks that may puncture the liner. More Info...
