Water Gardens — Problems with pond liner

Question WE think that our rubber pond liner may have a big air bubble under it, because this winter it has lifted in the centre. Can you help?

Answer  THIS is a drainage issue as it’s more than likely caused by ground water accumulating underneath the pond liner. You could try putting rocks in the pond to hold the liner down, but the best solution is to sort the drainage out.
