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 Hivernage: the job
For basement and cellar tanking in Hivernage, 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.
Trusted in Hivernage
“Perfect communication on WhatsApp from start to finish: I always knew what would happen the next day and who would be in my house.”
Fatima Z. · Hivernage“The terrace had been ponding for years: they rebuilt the falls, changed the drains and laid a proper membrane. No more ceiling stains.”
Thomas B. · Hivernage“We called them for basement and cellar tanking, then called them back for my parents’ roof. Nothing more to add.”
Oliver P. · HivernageThe Hivernage context
Hivernage is the district of hotels, upmarket residences and rooftop venues: technical flat roofs carrying air-conditioning units, chillers, glass balustrades and sometimes top-floor pools. Waterproofing there is an operating issue: a leak above a hotel room or a restaurant costs far more than the repair itself. We work with high-resistance systems — sprayed polyurea, traffic-grade resins, careful upturns around every unit standing on the roof — and schedules that respect the establishments’ business. Upmarket co-ownerships also expect clean paperwork: photos, reports, ten-year warranty.
In Hivernage, jobs like basement and cellar tanking are among the most requested: with summers above 45 °C and rain concentrated in winter, a well-laid membrane and correct falls make the difference between a terrace that lasts and one that has to be redone.

Frequently asked questions: Basement and cellar tanking in Hivernage
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.
