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 Amizmiz: the job
Paint hides, treatment cures: basement and cellar tanking in Amizmiz 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.
Trusted in Amizmiz
“We called them for basement and cellar tanking, then called them back for my parents’ roof. Nothing more to add.”
Mark T. · Amizmiz“A leak in the middle of the rainy season: fast response, temporary weatherproofing then the final repair at the quoted price.”
Karim E. · Amizmiz“I was looking for an alternative to full demolition: liquid membrane and the terrace was like new in three days. I wish I had called earlier.”
Emma R. · AmizmizThe Amizmiz context
Amizmiz and its douars were hit by the September 2023 earthquake: reconstruction is under way, and with it a new requirement — rebuilding roofs that no longer leak. On rebuilt or strengthened houses, roof waterproofing is the weak point of jobs done in a hurry: slabs poured fast, no upturns, improvised drainage. We work in Amizmiz with solutions suited to earthen housing and small recent slabs: light membranes, careful upturns, corrected falls, and pricing designed for reconstruction budgets. Every watertight roof is a house that gets through the Atlas winter without damage.
We work in Amizmiz every week: we know the local building types and we already know where to look for basement and cellar tanking — door thresholds, parapets, roof drains.

Frequently asked questions: Basement and cellar tanking in Amizmiz
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.
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.
