Basements in Gavà: where the damp comes from
Near the sea, in areas such as Centre, Les Panes and La Barceloneta, the ground holds a lot of water and basements in houses and blocks take it in after heavy rain. So as well as waterproofing from inside, we often fit a perimeter channel that carries the water to a sump with a pump.
Where water gets in, in basements in areas such as Les Colomeres, Les Bòbiles and Can Tries we cut a perimeter channel under the slab leading to a sump with a pump and non-return valve. On the walls we fit a cavity drain membrane and a lining set away from the masonry.
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: Castelldefels, Viladecans and Sitges.

Frequently asked questions
01Basement renovation in Gavà: which areas do you cover?
We do this work in Gavà, in areas such as Centre, Les Panes, La Barceloneta, Les Colomeres, Les Bòbiles, Can Tries, Ca n'Espinós and Bruguers, and also nearby: Castelldefels, Viladecans and Sitges. Before starting we visit the property and prepare a detailed written quote.
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.
