Targa: we carry out saltpetre treatment with waterproofing systems proven under the Marrakech climate — extreme summer heat, concentrated rain from November to March. You pay only after reading the quote: free, written and without obligation.
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.

The Targa context
Targa is the rising residential district: recent developments, new villas and small residences are springing up along the Fès road. The local paradox: recent terraces already failing, because the waterproofing was done fast and cheap during construction — a single bitumen layer, parapet upturns too low, undersized drains. Owners often call us within the first five years: leaks in the living-room ceiling, damp stains in bedrooms, water ponding in the middle of the terrace. We rebuild these roofs with warranted systems, correcting the falls and raising the upturns to the proper height.
People who call us from Targa for saltpetre treatment often already have two or three quotes: ours stands out because it is written line by line and the price never moves afterwards.
Frequently asked questions: Saltpetre treatment in Targa
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.
The barrier is active as soon as the treatment ends, but the wall’s drying takes about one month per 2.5 cm of thickness. We give you a realistic calendar and the finishes to wait for before repainting.
