Basement and cellar tanking in Sidi Abdallah Ghiat 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 in Sidi Abdallah Ghiat: the job
Basement and cellar tanking in Sidi Abdallah Ghiat starts by measuring the wall’s actual moisture, not by repainting the stain. Negative-pressure tanking mortar on walls and floor: the buried cellar stops drinking the ground’s water and becomes usable. The indicative cost is 250–450 DH/m²; after the free survey, the price is fixed in writing and locked.
Trusted in Sidi Abdallah Ghiat
“For basement and cellar tanking I had three quotes: theirs wasn’t the cheapest but it was the only one itemised line by line. Price respected to the dirham.”
Meryem J. · Sidi Abdallah Ghiat“They re-waterproofed without demolishing: no rubble in the stairwell, a tidy site every evening. The neighbours noticed nothing.”
Mohammed A. · Sidi Abdallah Ghiat“Our riad terrace was redone respecting the Medina’s constraints: materials carried in by hand, parapets rebuilt, zellige preserved. True specialist work.”
Robert N. · Sidi Abdallah GhiatThe Sidi Abdallah Ghiat context
Sidi Abdallah Ghiat is the booming municipality south-east of Marrakech: close to 47% population growth in ten years, entire housing estates out of the ground, from affordable villas to upmarket residences. What the area’s roofs have in common: fast execution during the boom, with bituminous membranes laid over dusty substrates and sloppy upturns. The result is plenty of under-ten-year-old terraces already leaking. We charge the same prices there as in central Marrakech, with no travel surcharge, and we handle both targeted repairs and full refurbishment of large recent villa terraces.
People who call us from Sidi Abdallah Ghiat for basement and cellar tanking 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: Basement and cellar tanking in Sidi Abdallah Ghiat
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.
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.
