Tank and cistern lining in Gueliz is one of the jobs we carry out most often in the area. Materials rated for the Marrakech climate, a tidy site, deadlines kept: free survey, written quote within 24 hours, ten-year warranty on the works.
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.
Tank and cistern lining in Gueliz: the job
For tank and cistern lining in Gueliz, the protocol is strict: free diagnosis, quote within 24 hours, application and tightness test before refilling. Certified potable-water lining for buried or rooftop cisterns and tanks: healthy water, protected walls, leaks stopped. Reference budget: 180–350 DH/m², written warranty included.
The 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 tank and cistern lining 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: Tank and cistern lining in Gueliz
We handle the waterproofing of the shell and the fittings (skimmers, lights, jets). If the leak is in the buried pipework, we locate it and coordinate the repair with your pool contractor.
From 200 to 500 DH/m² of shell surface (floor + walls) depending on the system: flexible mortar under a finish 250–450 DH/m², epoxy as finish 220–400 DH/m². An 8×4 m pool usually runs 25,000–60,000 DH.
In Marrakech, summer evaporation reaches 1–2 cm a day, no more. If you lose more, or if the level drops with the pump off, it is a leak: we locate it without fully draining the pool.
Yes — it is the classic build-up of riad basins: two coats of flexible waterproofing mortar, then zellige laid with water-resistant adhesive and epoxy joints. Beautiful on top, watertight underneath.
