A figure with a scopeHow much does
waterproofing cost?
As a first reference, Spanish 2026 guides usually put waterproofing at €20–60/m². For terraces, guide figures of €20–40/m² appear, and for roofs €20–50/m².
These are not Tramuntana rates or an average specific to Mallorca. A terrace that needs the floor lifted, junctions redone or the paving renewed may fall outside those figures.
The price per m² doesn’t on its own show what is included. Taxes, preparation, trims, access, removals, finish and conditions of the work must be defined. A small repair isn’t priced by simple multiplication either.
