What happens here
After shaping the pond and stream, install a geotextile underlayment over all excavated surfaces. This protective layer prevents punctures to the main pond liner from sharp objects or roots. Carefully unroll and position the heavy-duty pond liner (e.g., EPDM rubber liner) over the underlayment, ensuring it conforms to all the contours without excessive tension. Overlap multiple pieces of liner where necessary, sealing them with specialized liner tape or adhesive.
Goal: Create a watertight and protected basin for the pond and stream.
