Basement and cellar tanking in Marrakech is one of the jobs we carry out most often in the area. Materials rated for the Marrakech climate, a tidy site, deadlines kept: free survey, written quote within 24 hours, ten-year warranty on the works.
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: how we carry it out
For basement and cellar tanking in Marrakech, the protocol is proven: free diagnosis, quote within 24 hours, treatment of the cause then breathable finishes. Negative-pressure tanking mortar on walls and floor: the buried cellar stops drinking the ground’s water and becomes usable. Reference budget: 250–450 DH/m², written warranty included.

What our clients say: Basement and cellar tanking
“They re-waterproofed without demolishing: no rubble in the stairwell, a tidy site every evening. The neighbours noticed nothing.”
Nadia B. · Marrakech“Our riad terrace was redone respecting the Medina’s constraints: materials carried in by hand, parapets rebuilt, zellige preserved. True specialist work.”
Leïla H. · Marrakech“Serious people: protection everywhere, deadlines kept, and the terrace handed back cleaner than they found it.”

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.
