Qatar’s weather is hard on buildings. Roofs get very hot in summer, the soil has a lot of salt, and short but heavy rains catch many roofs off guard. If waterproofing is not done the right way, water seepage, damp walls, and roof leaks can start in just 2–3 years instead of lasting 15–20 years.
Jefcon Qatar has worked on waterproofing, damp proofing, and leak repair projects across Doha since 2012. Our team uses certified waterproofing membranes and coatings from trusted brands like Duproof, Bitumode, and Soprema. Before any work starts, we send a technician to physically check the site — we don’t give quotes over the phone. After the job is done, you get a written report and a workmanship warranty.

| Method | Best For | Typical Lifespan | Key Advantage |
|---|---|---|---|
| Torch-applied bituminous membrane | Concrete roofs, terraces | 10–15 years | Heavy-duty, proven barrier |
| PU liquid membrane | Roofs, balconies, irregular shapes | 10–20 years | Seamless, flexible, no joints |
| Cementitious / crystalline coating | Water tanks, basements, wet areas | 10–15 years | Bonds into concrete, potable-water safe |
| Injection grouting (PU/epoxy) | Active cracks and leaking joints | Long-term crack seal | Fixes leaks from inside, no demolition |
| Elastomeric acrylic coating | Metal roofs, sun-exposed surfaces | 8–12 years | UV-reflective, cuts heat load |
The right choice depends on the surface, its exposure, and whether it sits above or below grade. A free physical inspection is what determines this — matching the wrong material to the wrong surface is still the single biggest cause of premature waterproofing failure we see across Qatar.
Catching any of these early is significantly cheaper than waiting — once corrosion and spalling set in, you’re no longer looking at a waterproofing job, you’re looking at structural repair.
We handle waterproofing for villas and residential compounds, apartment towers, commercial buildings and malls, schools, mosques, and government buildings, hotels and hospitality properties, and factories, warehouses, and industrial or oil-and-gas facility structures.
There’s no honest flat per-square-meter rate that applies across every roof or wet area — pricing depends on surface area, the system needed, existing damage, and how accessible the site is. That’s exactly why we start every job with a free, no-obligation inspection and follow it with a detailed, itemized quote based on the actual condition of your property, not a generic estimate pulled from a price list.
Concrete roofs generally perform best with PU liquid waterproofing, torch-applied membrane, or cementitious coating. Metal roofs need a different approach — rust treatment, sheet repair, waterproof sealants, and elastomeric coatings. We cover Doha, Al Rayyan, Al Wakrah, Lusail, and every city in Qatar.
Yes — sheet repair, leak detection, screw replacement, rust removal, joint sealing, flashing repair, and gutter waterproofing, for warehouses, factories, villas, labor camps, and industrial sites.
A professionally installed system typically lasts 10–20 years depending on material, UV exposure, and maintenance. Torch-on membrane, PU liquid waterproofing, EPDM, and acrylic coatings hold up best against Qatar's heat and seasonal rain.
Roof, bathroom, kitchen, basement, water tank, swimming pool, balcony, podium deck, foundation, lift pit, retaining wall, torch-on membrane, mineral membrane, gravel-finished, PU liquid, epoxy coating, injection grouting, and metal sheet leak repair — across all of Qatar.
Watch for water leakage, ceiling stains, damp walls, mold, peeling paint, roof cracks, rusted sheets, loose flashing, bubbling membrane, or standing water after rain. Early inspection prevents costly structural repair.
Yes — villas, apartments, compounds, malls, schools, hospitals, hotels, factories, warehouses, labor accommodations, mosques, and government buildings across Doha, Al Rayyan, Lusail, Al Wakrah, Al Khor, Umm Salal, Al Daayen, Mesaieed, Dukhan, Ash Shamal, and Al Shahaniya.
Yes — free site inspection, leak detection, professional assessment, and a detailed quotation for every project type, anywhere in Qatar.
PU (polyurethane) liquid waterproofing forms a flexible, seamless membrane best suited to roofs, balconies, and irregular surfaces exposed to movement and UV. Cementitious/crystalline waterproofing bonds chemically into the concrete substrate and is the standard choice for water tanks, basements, and below-grade structures where potable-water safety or hydrostatic pressure resistance matters.
For active leaks in bathrooms or walls, injection grouting can often seal the source of the leak without demolition. Full re-waterproofing before re-tiling is recommended when the membrane itself has failed, not just a single crack.
Yes — our concrete water tank systems use crystalline and cementitious coatings certified safe for potable water contact, not generic industrial waterproofing products.
