Medina: we carry out torch-applied double-layer membrane with waterproofing systems proven under the Marrakech climate — extreme summer heat, concentrated rain from November to March. You pay only after reading the quote: free, written and without obligation.
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.
We work in Medina every week: we know the local building types and we already know where to look for torch-applied double-layer membrane — door thresholds, parapets, roof drains.
Frequently asked questions: Torch-applied double-layer membrane in Medina
Double layer, almost always: the second layer protects the first one’s welds and doubles the service life. Single layer only makes sense on non-traffic roofs on a tight budget — and we tell you so honestly at the survey.
Yes, provided it is protected: slated finish, reflective paint or gravel. A bare black membrane cooks at over 70 °C on the surface and ages twice as fast — the classic mistake we correct.
We avoid open flame on timber substrates and riads: in that case, self-adhesive membrane or liquid membrane. Same waterproofing result, no fire risk and no ADER issues.
Often not: if the old membrane still adheres, we lay the new layer over it after preparation. If it is blistered or detached, stripping is unavoidable — the free survey settles the question.
