Underground and roof tanks

Underground tanks face water pressure from inside and soil moisture from outside, so we repair cracks and joints and, where reachable, treat the outer face too. Roof tanks are checked together with the roof waterproofing, because a leaking tank destroys the layer underneath it.

Frequently asked questions

Do I need to empty the tank?

Yes. The tank is emptied, cleaned and dried before any repair or lining.

Which tanks do you waterproof?

Concrete underground tanks and roof tanks for villas, residential buildings and rest houses.

Can you find a leak without breaking things?

We start by comparing meter readings and checking the pipework, so we open only where needed.
