Basements in Cornellà de Llobregat: where the damp comes from
In areas such as Centre and Riera it is common to find older houses with vaulted stone cellars. If the structure is sound we leave it exposed, treat the damp rising from the floor and turn the space into a wine cellar or pantry.
In the basements we convert in areas such as El Pedró, La Gavarra and Sant Ildefons, ventilation is part of the job: mechanical extraction ducted outside with a controlled air inlet. The wiring follows REBT rules for damp locations, with sealed light fittings and sockets raised off the floor.
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: L'Hospitalet de Llobregat, Esplugues de Llobregat and Sant Joan Despí.

We do this work in Cornellà de Llobregat, in areas such as Centre, Riera, El Pedró, La Gavarra, Sant Ildefons, Almeda and Fontsanta-Fatjó, and also nearby: L'Hospitalet de Llobregat, Esplugues de Llobregat and Sant Joan Despí.

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.
