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 in Medina: the job
Paint hides, treatment cures: saltpetre treatment in Medina 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.
The Medina context
The Marrakech Medina is our home ground: hundreds of riads with centuries-old flat roofs built from earth, cedarwood and lime, where traditional waterproofing — rammed earth layers and tadelakt — is reaching the end of its life. Every job here must respect ADER rules and the UNESCO listing: no hauling tonnes of rubble through narrow derbs, no altering the roofline of the terraces. We use light materials compatible with pisé: flexible resins, flame-free self-adhesive membranes, parapet upturns rebuilt to standard. Leaks in the Medina are unforgiving: they rot the wooden beams, swell the earthen walls and lift the tadelakt off bedroom walls.
We work in Medina every week: we know the local building types and we already know where to look for saltpetre treatment — door thresholds, parapets, roof drains.

Frequently asked questions: Saltpetre treatment in Medina
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.
Yes, with an adapted protocol: earth is neither concrete nor brick. Gentle injections or drainage depending on the case, and above all breathable finishes — never waterproof cement that traps moisture and destroys the wall.
