Gueliz: we carry out liquid membrane over existing tiles 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.
Liquid membrane over existing tiles in Gueliz: the job
Liquid membrane over existing tiles in Gueliz means a continuous, seamless membrane: primer, first coat, reinforcement fleece on critical points, second coat. Ceramic bonding primer then reinforced membrane: the old tiles become the substrate, joints and hairline cracks are bridged without breaking anything. The indicative cost is 120–200 DH/m²; after the free survey you receive the firm price in writing, locked until the works are finished.

The Gueliz context
Gueliz, the new town laid out in the Protectorate era, is dense with 1930s–70s apartment buildings: ageing concrete slabs, technical roof terraces shared between co-owners, cracked parapets and original bituminous waterproofing that has often never been replaced. This is the district of co-ownership files: who pays, when to intervene, how to coordinate the top-floor flats. We manage the whole job there, from the shared diagnosis to the report for the building manager, with flame-free systems suited to occupied buildings. Gueliz summers regularly top 45 °C: black membranes baked by the sun crack open, and the first November rain exposes every defect.
In Gueliz, jobs like liquid membrane over existing tiles 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: Liquid membrane over existing tiles in Gueliz
From 120 to 280 DH/m² depending on the system: reinforced single coat 120–160 DH/m², two coats with fleece 160–220 DH/m², traffic resin 200–280 DH/m². A 60 m² terrace is usually treated for 9,000–16,000 DH, confirmed after the free survey.
Yes, if it is a quality polyurethane applied at the right thickness: it stays flexible through 45 °C summers and doesn’t turn brittle in winter. Cheap DIY products crack within two seasons — that is the whole difference.
Yes: after washing, degreasing and a ceramic-specific bonding primer, the membrane adheres perfectly. It is the no-demolition solution par excellence, provided the tiles are well bonded — we check during the survey.
A 40–80 m² terrace takes 2 to 4 working days plus drying time between coats. No demolition, no rubble: the site is clean and the house stays liveable.
