How to Prepare and Lay A Flexible Pond Liner

If you cannot read the words on the image then look above and below the picture and you will see the same description. If you are browsing on a small screen I'm afraid you may have to scroll right a bit.

TIP: Keep the shape simple. TIP: Trowel the sand flat with a plasterers float.

Method ...

1) Cut out and lay footing for the paving.

2) Lay 6:3:2 concrete mix at least 5cm deep with a fall away from the pond.

3) Lay a protective 1inch deep layer of sand on the bottom of the pond. Cover the blocks and hard edges with underlay or damp newspapers.

4) Lay the liner into place. Gather the folds and creases together and smooth out as if you were making a hospital bed.

5) Cut the liner shape allowing a generous overlap of at least 6inches over the blocks. Dont fold over the back of the blocks.

MONEY SAVING TIP: Build your pond to a size that in one direction plus double the depth, corresponds to a standard width in the material you choose.

TIP for ponds with radical scallops: measure the width around the contour of the shape as this will take up extra liner.

Warning awkward shapes make for extra folds.

REMEMBER: Calculate the liner size by adding twice the maximum pond depth to both the length and width of pond. Take care to measure overall pond dimensions ie. at the widest point.

TIP: Drape a tape measure through the excavation to check you have the right size before you unpack the liner.
