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.
Basement and cellar tanking in Targa: the job
Paint hides, treatment cures: basement and cellar tanking in Targa attacks rising moisture at its source. Negative-pressure tanking mortar on walls and floor: the buried cellar stops drinking the ground’s water and becomes usable. The indicative spend is 250–450 DH/m²; the final figure is written before we start and never changes.
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.
In Targa, as everywhere in Marrakech, waterproofing is the poor relation of recent construction: basement and cellar tanking is the safest way to put the roof right before a small leak becomes a major damage.

Frequently asked questions: Basement and cellar tanking in Targa
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.
