Looking for a specialist for liquid membrane over existing tiles in Medina? Flat roofs, terraces and waterproofing are all we do, in Marrakech and across the Haouz. Free survey, written quote within 24 hours and a firm price before the first roller stroke. Not a general builder: a flat-roof specialist.
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.

Trusted in Medina
“The terrace had been ponding for years: they rebuilt the falls, changed the drains and laid a proper membrane. No more ceiling stains.”
Karim E. · Medina“We called them for liquid membrane over existing tiles, then called them back for my parents’ roof. Nothing more to add.”
Anna S. · Medina“A leak in the middle of the rainy season: fast response, temporary weatherproofing then the final repair at the quoted price.”
Rachid T. · 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.
People who call us from Medina for liquid membrane over existing tiles often already have two or three quotes: ours stands out because it is written line by line and the price never moves afterwards.
