Terrace & balcony waterproofing in Geneva

A leaking terrace or balcony often means water in the flat below. We redo the waterproofing of your terraces and balconies, with the finish of your choice.

Terraces and balconies: waterproofing comes before the finish

Under tiles or paving, it's the waterproofing layer that actually protects the structure. When it fails, water infiltrates, lifts the covering and can reach the flat below. We treat the cause by redoing the waterproofing properly.

Frequently asked questions

My terrace is leaking into the flat below — what should I do?

The waterproofing layer under the covering needs redoing. We run a diagnosis to locate the source, then a durable renovation with a written guarantee.

Can the waterproofing be redone without demolishing everything?

Depending on the condition, a liquid (resin) waterproofing can sometimes be applied over the existing substrate. The on-site diagnosis decides.

How long does a terrace project take?

It depends on the area and the finish. We state a precise timeframe in the quote and stick to it.

Do you also redo the tiling after the waterproofing?

Yes, we offer the complete finish: tiles, paving on pedestals or covering, for a finished, watertight result.

Enjoy a watertight terrace, with no nasty surprises.
