Looking for a specialist for damp-proof wall injection in Targa? Flat roofs, terraces and waterproofing are all we do, in Marrakech and across the Haouz. Free survey, written quote within 24 hours and a firm price before the first roller stroke. Not a general builder: a flat-roof specialist.
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.
Damp-proof wall injection in Targa: the job
Damp-proof wall injection in Targa starts by measuring the wall’s actual moisture, not by repainting the stain. On concrete, brick or block: calibrated drilling, controlled injection, neat plugging. The reference treatment, measurable with a moisture meter. The indicative cost is 100–220 DH/m; after the free survey, the price is fixed in writing and locked.

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.
We work in Targa every week: we know the local building types and we already know where to look for damp-proof wall injection — door thresholds, parapets, roof drains.
Frequently asked questions: Damp-proof wall injection in Targa
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.
