Palmeraie: we carry out basement and cellar tanking with waterproofing systems proven under the Marrakech climate — extreme summer heat, concentrated rain from November to March. You pay only after reading the quote: free, written and without obligation.
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 Palmeraie: the job
For basement and cellar tanking in Palmeraie, 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 Palmeraie context
In the Palmeraie, terraces match the scale of the villas: 150 to 400 m² of flat roof, often fitted out as a solarium, summer lounge or outdoor kitchen, on buildings surrounded by century-old palm trees. These large surfaces expand strongly under the sun: without movement joints and a flexible system, cracks are inevitable. Typical requests in the area: re-waterproofing 300 m² without closing down the villa, fixing leaks around pergolas anchored into the slab, waterproofing garden basins and water features. We plan these jobs zone by zone so the house stays liveable, with materials rated for high surface temperatures.
In Palmeraie, 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 Palmeraie
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.
