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.

Karim E. · MedinaThe Medina context
The Marrakech Medina is our home ground: hundreds of riads with centuries-old flat roofs built from earth, cedarwood and lime, where traditional waterproofing — rammed earth layers and tadelakt — is reaching the end of its life. Every job here must respect ADER rules and the UNESCO listing: no hauling tonnes of rubble through narrow derbs, no altering the roofline of the terraces. We use light materials compatible with pisé: flexible resins, flame-free self-adhesive membranes, parapet upturns rebuilt to standard. Leaks in the Medina are unforgiving: they rot the wooden beams, swell the earthen walls and lift the tadelakt off bedroom walls.
In Medina, 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 Medina
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.
Yes: heat, steam, standing water. We use systems resistant to steam and thermal cycling, with high upturns on the walls and specific treatment of the floor-to-wall junction.
