Waterproofing Services in Dubai
Bathrooms, balconies, terraces, roofs, planters and tanks — waterproofed with manufacturer-certified material systems from Sika, BASF, Fosroc and Jotun. We install the systems; certifications and material warranties pass through from the manufacturer. 6-month workmanship warranty on the labour.
What our waterproofing team handles
Most water damage in Dubai isn't from rain — it's from condensation, AC drainage, plumbing leaks, summer humidity, and the occasional flash flood at Al Quoz. Different exposures need different waterproofing systems. We pick the system to match the failure mode, not the other way round.
Bathroom waterproofing
Floor and wet-wall membranes — typically a liquid-applied cementitious or polyurethane system, taped at corners and pipe penetrations. Waterproofing fails at corners and pipes; that's where we spend the time.
Balcony and terrace waterproofing
Liquid-applied membranes that bond to the screed and tolerate movement. Drain falls verified before tile goes back down. The cause of most balcony leaks is a kerb that wasn't flashed properly — we treat the kerb as a separate detail.
Roof waterproofing
Liquid-applied or sheet-membrane systems for villa flat roofs, AHU plinth surrounds, and parapet abutments. UV-stable top coat where the membrane is exposed.
Planter and water-feature waterproofing
Salt and continuous-contact-with-water systems — different chemistry than bathroom membranes. Often overlooked at handover; failure shows up as efflorescence on the wall below.
Water tank lining (potable + non-potable)
Food-grade epoxy or potable-water-rated cementitious liners for storage tanks. Surface prep is the entire job — any contamination breaks the bond.
Concealed-leak diagnosis before retile
Damp-meter survey, pressure testing, sometimes thermal imaging. Tells us whether the existing waterproofing is reusable or needs stripping back. Saves you re-doing waterproofing that didn't need it.
Crack injection and structural sealing
Active-leak cracks injected with PU resin under pressure. Different chemistry than membrane work — used where the failure is structural movement, not surface coating.
Foundation and basement tanking
External waterproofing on basement walls, retaining-wall painting, drainage-board coordination. Specialist work; we coordinate with structural engineer's spec where one is involved.
Pre-tile waterproofing for renovations
Coordinated with the tiling team — membrane laid, cured, water-tested, then tiles go down. The 24-hour cure window matters; tiling on uncured membrane is the most common cause of bathroom-renovation failures within 12 months.
Preventive waterproofing surveys
For older villas (10+ years), pre-handover apartments, and properties with history of leaks. Damp meter, visible-condition survey, written report with proposed scope.
When the waterproofing has failed
Dampness in walls, floors or ceilings is always a symptom of something — plumbing, condensation, or waterproofing. Waterproofing failure looks like this.
Damp patch on a wall below a bathroom
Almost always a bathroom waterproofing failure leaking down through the slab. Stop using the room above (if there is one) and book a survey.
White salt bloom on a wall
Efflorescence — moisture is moving through the substrate and bringing salts to the surface. The dampness has been there for a while. Surface paint won't fix it; the waterproofing layer needs attention.
Bubbling or peeling paint near a balcony door
Balcony membrane has lost its seal at the threshold and water is wicking through. Common after the first heavy summer humidity cycle.
Damp ceiling under a flat roof
Roof membrane has cracked, lifted at a seam, or the surface has UV-degraded. Easier (and cheaper) to recoat at the right stage than wait for slab damage.
Pool or planter losing water
Hairline crack in the structural concrete. Leaks 100+ litres per day before it's visible. Crack injection or full re-line, depending on size.
Recurring mould near AC drain points
Either an AC drainage issue or a waterproofing detail at a pipe penetration. We diagnose both — most other contractors only check one.
How a Samra waterproofing job runs
Six steps. The cure windows are non-negotiable; we plan around them rather than rushing them.
Survey and diagnosis
Damp meter, visible inspection, pressure or thermal testing where appropriate. We confirm what's failed before scoping what to do — replacing waterproofing that hasn't failed wastes everyone's time and money.
System selection
Cementitious for bathroom floors, polyurethane liquid-applied for balconies and terraces, sheet membrane for some roof scenarios, food-grade epoxy for potable water tanks. Spec matched to the exposure and the substrate.
Substrate preparation
The most important step — substrate must be sound, clean, and at the right moisture content. Mechanical surface preparation, crack repair, primer where the system requires one. Skipping prep is why a lot of waterproofing fails inside 24 months.
Application
Two coats minimum, taped reinforcement at corners, junctions and pipe penetrations. Cross-coat technique where required by the spec. We follow the manufacturer's data sheet — not "what worked last time".
Cure and water test
Cure window per the system spec (typically 24–72 hours). Then a flood test where geometry allows it: water held on the surface for 24+ hours and we look at the underside. No leak = pass.
Coordination with finishes team
For renovations: handoff to tiling team or screed team only after the test passes. Photo report logs the membrane application, taped joints, and successful test. Workmanship-warranty start logged on handover.
How we price waterproofing work
Quoted per square metre for fields, fixed-price for typical bathroom or balcony scopes. The system spec drives the price more than the area.
Fixed-price written quote
Survey first for anything beyond a single small bathroom. We measure, identify the failure mode, recommend the system, and quote line-item — labour by m², membrane materials, primer, reinforcement tape, cure window, and water test.
What changes the price
- System chemistry — cementitious vs PU vs sheet vs epoxy
- Surface area in square metres
- Substrate prep — sound vs cracked vs contaminated
- Access — bathroom interior vs roof at height vs basement tanking
- Detail work — taped corners, pipe penetrations, abutments, kerbs
How to get a quote
WhatsApp photos of the affected area + a description of the symptoms (when did it start, recent renovation, recent rainfall). We schedule a survey before issuing the all-in price.
Workmanship and material warranties
Two layers on every waterproofing job. Workmanship is ours; material warranties on the membrane systems pass through directly from the manufacturer (often 5–10 years on premium systems).
workspace_premiumWorkmanship warranty
6-month workmanship warranty — if the same issue returns within 6 months due to our work, we'll fix it free of charge. Covers labour only.
For waterproofing specifically: failures at our taped joints, pinholes in our application, debonding from inadequate substrate prep on our part — all covered. Remember: we install the systems; we are not certified applicators of any specific manufacturer scheme.
verifiedMaterial warranties
Material warranties depend on the products and systems we install. Many of the brands we work with — including Sika, BASF, Fosroc, Jotun, and others — carry manufacturer warranties ranging from 1 to 10 years depending on the product. We'll confirm exact warranty terms for the specific materials used on your project before work begins.
Frequently asked questions
What warranty do you provide?
We offer two layers of warranty. First, a 6-month workmanship warranty on the labour we perform — if the same issue returns within 6 months due to our work, we re-do it at no cost. Second, material warranties pass through directly from manufacturers — some systems we install carry warranties of up to 10 years. We'll share exact warranty terms for your specific project before we start.
Does the workmanship warranty cover parts and equipment?
No. Parts, fixtures, and equipment are covered by their manufacturer warranties, which we pass through to you directly. The workmanship warranty covers only the quality of the installation or repair work itself.
Are you a Sika / BASF / Fosroc certified applicator?
No. We install Sika, BASF, Fosroc and Jotun material systems — meaning we use their products to manufacturer specification — but we are not certified applicators of any specific manufacturer scheme. The material warranty on the products themselves still passes through; we just don't hold the contractor-side certification badge. We'll confirm exact warranty terms with the manufacturer for your specific project before we start.
How long does waterproofing take?
Bathroom or single balcony: 2–4 days for application + 24–72 hours for cure + 24-hour water test = roughly a week before tiling can resume. Roof: depends on area; small flat roofs 3–5 days, larger 1–2 weeks. The cure windows are non-negotiable — rushing them is the #1 cause of waterproofing failure.
Can you waterproof without removing the existing tiles?
In most cases, no. The membrane has to bond to the substrate; tile is a different surface and most systems aren't spec'd to go on top of glazed ceramic. Crack injection through tile is possible for active-leak structural cracks, but full waterproofing renewal almost always means lifting the tile. Easier to plan as a coordinated retile + waterproof.
Do you do flood-test verification?
Yes — where geometry permits. Bathrooms and balconies get flooded to a 25mm depth and held for 24 hours; we inspect the underside of the slab during and after for any sign of water passage. No leak = pass = handover. The flood test is the single most important verification step and we don't skip it.
Do you waterproof potable water tanks?
Yes — using food-grade epoxy or potable-water-rated cementitious liner. Surface prep is the entire job; the substrate has to be mechanically clean and at the right moisture content for the bond to hold. Tank cleaning happens before lining. Cure window before water can return is typically 7+ days.
