How to Build a Backyard Pond in ONE Day steps 8-20
What happens here
Begin by placing a layer of geo-textile underlayment fabric (also referred to as 'boulder fabric' by some or non-woven geotextile underlayment fabric) over the excavated pond area. This fabric serves to protect the EPDM rubber liner from punctures by sharp objects and increases the load-bearing capacity of the soil, providing structural stability and allowing the pond bottom to breathe, facilitating moisture and gas exchange. Ensure the fabric covers the entire excavated area before the liner is laid. This step usually involves multiple people to handle the large fabric sheets.
Goal: Protect the pond liner and stabilize the soil
