For below-ground wall waterproofing in Gueliz, you don’t need a company that does ‘a bit of everything’. We waterproof terraces every single week: free diagnosis, itemised written quote within 24 hours, and the price you read is the price you pay. Full stop.
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.

Trusted in Gueliz
“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.”
Nadia B. · Gueliz“Water came through the living-room ceiling every time it rained. Survey on Thursday, quote the next day, work finished in four days. Not a drop since.”
Isabelle C. · Gueliz“For below-ground wall waterproofing I had three quotes: theirs wasn’t the cheapest but it was the only one itemised line by line. Price respected to the dirham.”
Sarah L. · GuelizThe Gueliz context
Gueliz, the new town laid out in the Protectorate era, is dense with 1930s–70s apartment buildings: ageing concrete slabs, technical roof terraces shared between co-owners, cracked parapets and original bituminous waterproofing that has often never been replaced. This is the district of co-ownership files: who pays, when to intervene, how to coordinate the top-floor flats. We manage the whole job there, from the shared diagnosis to the report for the building manager, with flame-free systems suited to occupied buildings. Gueliz summers regularly top 45 °C: black membranes baked by the sun crack open, and the first November rain exposes every defect.
For below-ground wall waterproofing in Gueliz, the survey is free and the quote firm: you know exactly what you pay before we start, and the warranty is in writing.

Frequently asked questions: Below-ground wall waterproofing in Gueliz
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.
