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.
Concrete slab waterproofing in Medina: the job
No tarpaulins and no DIY patches: concrete slab waterproofing in Medina is done with complete waterproofing systems designed for Marrakech’s 45 °C summers and winter rains. On a concrete slab the critical point is cracking: crack treatment, bonding primer, reinforced membrane over all junction zones. The indicative spend is 180–350 DH/m²; the final figure is fixed in writing before we start, after seeing the terrace in person.

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.
People who call us from Medina for concrete slab waterproofing often already have two or three quotes: ours stands out because it is written line by line and the price never moves afterwards.

Before handover, we flood or hose the terrace and check the flow to every drain and the absence of leaks below. You receive the photos and the written warranty.
