Planning to make a water feature, basically approximately 4x4mtrs raised with sleepers and a salting slab in the middle with a water fountain coming through the middle, I will get pics up.
My question is, the liner, people have said go with something like Firestone roofing membrane but it seems a bit over the top for a water feature, anyone any experience in this area.
Obviously I need to work out how to support the salting slab without piercing the liner, it’s very heavy.
