Pond Liners Installation Guide

How to install a pond liner: Simple step-by-step guide

1. Clear the pond and surrounding area of any roots, stones or debris.

2. Lay the underlay to fit the contours of the ground and allow at least 50mm of overlap between strips.

3. Unroll the pond liner following the directions on the wrapping, and pull it across the pond using a flipping motion to let it ‘float’ into place.

4. Avoid stretching the rubber as you position it. Just let it wrinkle and pleat naturally to fit the contours of the pond. If you are not using overlay, leave out step 5 and go straight to step 6.

5. Now lay the overlay in the same way as the underlay, and then cover it with soil, sand or stones, working from the centre outwards towards the anchor trench.

6. Fill the pond with water.

7. Excess liner material can now be trimmed, but make sure you leave enough for anchoring. This is done by either backfilling an anchor trench or by adding stone edging.

8. The permanent water level for your pond should be at least .15m below the top of the liner to prevent water loss due to capillary action into the surrounding soil.

Congratulations! Your pond liner is complete.
