The treatment requires addressing the source of the water, not the internal symptom. If the roof is degraded, the entire waterproofing must be renewed with new asphalt membrane or a liquid polyurethane spray system. If the facade has structural cracks, they are sealed with elastic sealant and repainted with specialised facade paint that covers micro-cracks. Only after guaranteeing external watertightness do we repair the internal wall. Chemical injection, exterior waterproofing, breathable coating, or ventilation according to diagnosis. Rising damp, roof leaks, internal condensation, and efflorescence from saltpetre. Diagnosis before action.

The most common mistake with damp is repainting the affected wall. It works for the first month, and then the damp reappears, worse than before. The new paint creates a barrier that traps water inside the wall. Damp isn't cured by painting; it's cured by identifying the water source and cutting it off at its entry point. Only then do we repair the wall using the appropriate technique and repaint. Formal guarantee on the treatment. If the damp reappears in the same spot, we'll return. This is damp that rises from the ground through walls via the capillary action of porous materials. It manifests as a damp patch on a ground floor up to a height of one metre from the floor, often with white efflorescence (salts that crystallise as the water evaporates). It is typical in old ground-floor properties, especially in areas with a high water table near the sea.

No, we select the product compatible with each material (gres, marble, microcement, parquet) after the initial assessment. This prevents scratching or damaging new surfaces. Removal of damaged render, salt neutralisation, and application of a compatible paint system. This is water entering from the outside due to defects in flat roof waterproofing, poorly sealed structural joints, or degraded exterior paint. It appears as stains on ceilings or the upper parts of internal walls, often coinciding with rainy periods.
