Looking for a specialist for basement and cellar tanking in Route de l’Ourika? 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.
Basement and cellar tanking in Route de l’Ourika: the job
For basement and cellar tanking in Route de l’Ourika, 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.
The Route de l’Ourika context
The Ourika road has become the axis of new villas and small residential compounds with pools: a new building comes out of the ground there every week. On this axis we see two families of requests: villas at finishing stage whose owner wants the waterproofing secured before handover — checking the falls, the upturns, a flood test — and already-delivered terraces that leak after their first winter. Terraces here often double as a solarium with Atlas views: they must be both watertight and walkable, hence the success of traffic-grade resins and membranes under tiling. Dust from neighbouring sites also clogs the drains: drainage checks are part of our standard inspection.
People who call us from Route de l’Ourika 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 Route de l’Ourika
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.
