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 Targa: the job
For tank and cistern lining in Targa, 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 Targa context
Targa is the rising residential district: recent developments, new villas and small residences are springing up along the Fès road. The local paradox: recent terraces already failing, because the waterproofing was done fast and cheap during construction — a single bitumen layer, parapet upturns too low, undersized drains. Owners often call us within the first five years: leaks in the living-room ceiling, damp stains in bedrooms, water ponding in the middle of the terrace. We rebuild these roofs with warranted systems, correcting the falls and raising the upturns to the proper height.
In Targa, jobs like tank and cistern lining 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: Tank and cistern lining in Targa
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.
