Basements in Castelldefels: where the damp comes from
Developments in areas such as Centre, El Castell – Poble Vell and Muntanyeta have many houses on sloping plots with a semi-basement: one wall is buried and takes water from the hillside. On that wall we reinforce the internal waterproofing and leave a drainage cavity behind the finish.
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 Montmar, Bellamar and Les Botigues we check the headroom first, as it sometimes limits the insulation.
We go down to the basement with you, measure damp and headroom and give you a detailed written quote; a site manager coordinates every stage. We also renovate basements in nearby areas: Gavà, Viladecans and Sitges.

We work in Castelldefels in areas such as Centre, El Castell – Poble Vell, Muntanyeta, Vista Alegre, Can Vinader, Can Roca, Els Canyars and Montmar, and also nearby: Gavà, Viladecans and Sitges.
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.
