Basements in Sant Boi de Llobregat: where the damp comes from
In areas such as Centre, Vinyets and Molí Vell and on their outskirts, many terraced and detached houses from the 1980s and 90s have a basement used only as a garage or store. We convert part of it into a gym, den or workshop and, where winters are cold, insulate floor and walls for year-round use.
Finishes depend on use: a tiled floor and stable temperature for a wine cellar, rubber flooring for a gym, moisture-resistant board and an insulated floor for a living space. In areas such as Marianao and Can Paulet we check the headroom first, as it sometimes limits the insulation.
With over 20 years of experience, our quote lists damp treatment and finishes separately, so you can see each part clearly. We also travel to nearby areas: Cornellà de Llobregat, El Prat de Llobregat and Viladecans.

We work in Sant Boi de Llobregat in areas such as Centre, Vinyets, Molí Vell, Marianao, Can Paulet, Camps Blancs, Canons and Orioles, and also nearby: Cornellà de Llobregat, El Prat de Llobregat and Viladecans.
02Does the damp need fixing before the basement is fitted out?
Always. First we find out whether the water comes from the ground, a leak or condensation, and apply the right solution. Skip that step and the finishes will end up damaged.
03Can a basement be used as a bedroom?
For habitable use the CTE requires daylight, ventilation and a minimum ceiling height, and local planning must allow it. We check this on the visit; if it isn't possible, we suggest uses such as a gym, wine cellar or play area.
