What is rising damp

Rising damp occurs when groundwater climbs up through the pores of your walls against gravity, a common problem in ground-floor flats and older buildings in Barcelona. You recognise it by the stains and salt efflorescence (saltpetre) at the base of the wall, flaking paint and blown plaster. It is a structural damp: it will not disappear by drying or painting over it.

How it is fixed for good

The technical solution is to create a chemical damp-proof barrier at the base of the wall by injecting hydrophobic resins that block the capillaries and stop the water from rising. Combined with removing the damaged render and applying a breathable renovating plaster, it cuts rising damp at the source. We connect you with the most suitable certified applicators in your area to carry it out with a warranty.

Why act sooner rather than later

Rising damp does not just ruin finishes: it degrades mortar, corrodes reinforcement and damages the structure, as well as creating an unhealthy environment. The sooner the rise is stopped, the lower the repair cost.

Frequently asked questions

How is rising damp treated permanently?

By creating a chemical barrier at the base of the wall through injection of hydrophobic resins, which seal the capillaries and stop groundwater from rising. It is the recognised technical solution; painting or drying the wall only hides the problem temporarily.

How do I know if my damp is rising damp?

Rising damp always appears at the lower part of the wall (up to about 1-1.5 m), with stains, saltpetre (a white powder) and flaking paint or plaster. If the stain is higher up or next to a window, it is more likely a leak or condensation.

Can rising damp be treated without major building work?

Resin injection is minimally invasive: it is done through small drill holes at the base of the wall, with no demolition. Damaged render does need to be removed and a breathable renovating plaster applied to the affected area.
