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.

The 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.

Allow 7 to 14 days after application ends, depending on the system (full curing is mandatory). We give you the refilling date in writing in the works schedule.
