For saltpetre treatment in Marrakech, you don’t need a company that does ‘a bit of everything’. We waterproof terraces every single week: free diagnosis, itemised written quote within 24 hours, and the price you read is the price you pay. Full stop.
Rainy season Nov–Mar: The Marrakech rainy season runs from November to March: that is when every tired terrace reveals itself. An ignored leak costs up to 10 times the price of waterproofing — damaged beams, lifted tadelakt, mould, repainting — and cuts the value of the property. The right time to waterproof is before the first heavy rain, not after it.
Saltpetre treatment: how we carry it out
Paint hides, treatment cures: saltpetre treatment in Marrakech attacks rising moisture at its source. Brushing, salt neutralisation, breathable finish: only effective after treating the rising damp — we do both. The indicative spend is 90–180 DH/m²; the final figure is written before we start and never changes.

What our clients say: Saltpetre treatment
“Water came through the living-room ceiling every time it rained. Survey on Thursday, quote the next day, work finished in four days. Not a drop since.”
Mohammed A. · Marrakech“For saltpetre treatment I had three quotes: theirs wasn’t the cheapest but it was the only one itemised line by line. Price respected to the dirham.”
Leïla H. · Marrakech“They re-waterproofed without demolishing: no rubble in the stairwell, a tidy site every evening. The neighbours noticed nothing.”
Salma K. · MarrakechFrequently asked questions: Saltpetre treatment
Not if the cause is treated: salt neutralisation, barrier against rising damp, breathable finish. Treating saltpetre without treating the rising damp, on the other hand, guarantees its return at the first wet season.
It is the most profitable visit of your purchase: for a few hundred dirhams you know what the walls hide, with a written report that gives you real negotiating leverage — or saves you from a very bad surprise.
From 100 to 300 DH per linear metre of treated wall depending on the technique: injection 100–220 DH/m on concrete or brick, pisé-specific protocol 150–300 DH/m. A riad typically needs 15,000–60,000 DH of treatment.
Rising damp starts at ground level and climbs evenly (up to 1 m and more), often with saltpetre; a leak makes localised stains linked to rain. Our moisture measurements settle it in one visit.
