Water tank waterproofing in Al Nasriyah, Riyadh

Al Nasriyah is a mixed district in west-central Riyadh under King Saud Road and Al Takhassusi Street, where villas, apartments and shops sit one above the other. A single tank may serve a villa, flats and a commercial unit below, and seepage affects multiple owners with conflicting interests. Pressure on a mixed-use tank is higher than on a purely residential or commercial neighbourhood.

Why a tank needs sealing, not patching

  • Water you store stays stored

    A lined tank keeps the water it holds instead of feeding a slow leak into the slab.

  • The damp stain has a cause

    The wet patch on the ceiling or wall below a tank is the symptom, and the tank is usually the cause.

  • Safe to hold drinking water

    The materials we apply are rated for potable water, so the tank is safe to drink from once it is back in use.

  • Proven before you rely on it

    We do not hand a tank back on trust.

Why the job is different in Al Nasriyah

In Al Nasriyah, shared tanks are the norm, and one leak affects different owners and users at the same time, creating complexity and disagreement about responsibility. The whole method is set out in our full account of water tank waterproofing.

  • One tank serving housing and business in parallel

    A flat, a shop and a villa may all draw from the same tank, and consumption varies by time and activity. Seepage affects each user differently and the cause is hard to pinpoint because different pressures act on the tank.

  • Different owners and unclear responsibility

    A flat and three shops may share one tank. If water leaks, who pays for repair? Damp appears in different units from a single cause, but liability is split between owners with conflicting interests.

  • Heavy use and main roads pump dust without pause

    Traffic on King Saud Road and Al Takhassusi Street is unending, dust rises constantly from the streets. Al Nasriyah tanks absorb this grime faster and degrade quicker than tanks in quieter neighbourhoods.

What's Included

The district blends palaces and villas with official quarters alongside apartments and shops, and is densely used along two busy main roads carrying constant traffic and dust.

  • Emptied and fully dried

    The shared tank is emptied completely before work starts, cutting water supply to every unit it serves until sealing and testing are done.

  • Cracks and leak points surveyed

    Cracks in Al Nasriyah tanks are scattered because the mixed use pattern puts changing and uneven pressure on the tank structure over time.

  • Surface prepared before coating

    Thorough cleaning is essential before sealing because the tank may serve different uses that deposit different types and grades of grime inside.

  • Waterproofing applied in coats

    Coats are applied evenly across every surface so no weak spots remain where water might find a path through the newly hardened seal.

  • Full curing time

    Curing takes longer because the shared tank is usually larger and deeper, and the material needs days to harden fully on all surfaces.

  • Fill test before handover

    Before the tank returns to service, it is filled gradually with constant watching to confirm the seal holds everywhere before normal use begins.

The character of Al Nasriyah

Mixed district: shops at street level with homes above them

Mixed use means tanks serve both housing and business with different owners. One leak affects everyone but in different ways, so sealing must be thorough and complete because water often enters from spots that are hard to reach or see.

What is different about Central Riyadh

Central Riyadh is the oldest and busiest part of the city. Olaya and Sulaimaniyah carry the office towers along King Fahd Road and Tahlia Street, including Kingdom Centre and Al Faisaliah, while Al Malaz, Al Murabba, Al Batha and Al Dirah are older apartment blocks with shops on the ground floor, the Masmak quarter and the markets around Qasr Al Hukm. Heavy traffic on the main roads coats glass and shopfronts in a grey exhaust film, older stairwells and tiled corridors show worn grout and scale from the hard water, and the commercial buildings never stop taking footfall.

Questions before booking

Villa, flat and shop under one tank: who bears the cost of waterproofing?
If the tank is shared, all owners share responsibility proportionally. But identifying the exact source of the leak may require close inspection to confirm whether water enters through the tank itself or through pipes below it.

Damp has appeared in the flat next door: who pays for tank waterproofing?
Moisture in a shared wall may come from a shared tank. The cause must be established first. If the tank is at fault, affected owners share the cost proportionally based on their legal share of the tank.

Villa, flat and shop under one tank: does it need full sealing or partial?
Sealing must be complete across the entire inner face or it fails. Partial sealing leaves weak spots where water finds a way through, and the benefit of the work is lost at the first pressure.

The tank is old but the shop below is new: must the tank be replaced first?
Tank replacement is a major and expensive undertaking. Sealing an old tank usually stops leaks and extends its life significantly. The tank is assessed first to determine whether sealing or replacement is the right choice.

How long will all the flats be without water during mixed-use tank sealing?
The tank is emptied completely before work begins, cutting water to every unit. Drying, sealing, curing and testing takes several days, after which the tank is refilled carefully before normal use resumes.

Does water stay clean after sealing a tank that serves both shop and flat?
Sealing stops outside dirt from entering, but deep cleaning before sealing is essential. Water stays clean afterwards if the tank is sealed properly and ventilation openings are correctly fitted and covered.
