Basement waterproofing & tanking in Geneva

Damp cellar, weeping buried walls, rising water: we treat and waterproof your basements so you get healthy, usable spaces back.

A dry, healthy basement

Basement damp comes from water pressure against the buried walls. Left untreated, it degrades the walls, encourages mould and makes the space unusable. Tanking creates a watertight barrier on the inside to block infiltration.

Frequently asked questions

What is basement tanking?

Tanking means creating a watertight barrier inside buried spaces to stop water getting in, even under pressure. It's a durable solution against damp cellars.

Why is my basement damp?

Damp usually comes from ground water pushing against buried walls, from rising damp, or from a waterproofing defect. A diagnosis determines the exact cause.

Can a cellar be converted after treatment?

Yes, once the basement is treated and watertight, the space can be used (storage, laundry, extra rooms).

Do you work on foundations?

Yes, we waterproof foundations, rafts and buried areas, with drainage where needed.

Treat your basement for the long term.
