Water tank waterproofing in King Abdulaziz, Riyadh

King Abdulaziz is a small, densely built apartment district in east-central Riyadh that grew next to the former airport, now hemmed in by busy Khurais and Al Ahsa Roads. Tanks on rooftops here endure constant vibration from heavy traffic and moisture from air conditioning units, creating cracks that seep water into the flats below.

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 King Abdulaziz

Leaks here typically begin from vibration cracks caused by heavy vehicles on nearby roads, and new cracks appear in the same locations each season after the last repair fails. The whole method is set out in our full account of water tank waterproofing.

  • Vibration from Khurais Road cracks the tanks year after year

    Khurais Road beside the district carries heavy traffic all day, and large lorries shake the old buildings. Roof tanks move with each vibration, creating fine cracks at seams and joints. Patched sections fail in the same place within months because the underlying problem is the movement itself.

  • Air conditioner drain moisture weakens the tank from outside

    Every flat has an AC unit on the roof, and condensation pools around the tank. Salts in AC water deposit on the tank walls and corrode the concrete beneath the surface layer, opening channels for new leaks.

  • Old buildings have settled unevenly on their original ground

    The district is very old, and buildings settled at different rates on the soil. Tanks installed level originally may now be tilted fractionally, opening gaps between the tank and roof surface where water collects.

What's Included

A dense district with multi-storey apartment blocks close to arterial roads carrying continuous traffic. Older buildings experience constant vibration from trucks and lorries passing on main roads.

  • Emptied and fully dried

    Draining must be quick and safe in a densely occupied building. Water is pumped out carefully and not left pooling on the roof.

  • Cracks and leak points surveyed

    Cracks from vibration are often too fine to see, so a water test on the surface reveals them quickly and clearly.

  • Surface prepared before coating

    The surface is cleaned of mineral scale and AC drain deposits, and old patch edges are cleared back to sound concrete.

  • Waterproofing applied in coats

    Coats are applied carefully because the roof may stay damp from AC condensation or recent rain, so complete drying is confirmed before starting.

  • Full curing time

    Cure time follows standard schedules, but the tank may not be refilled immediately if residents need water. A schedule is agreed with building management.

  • Fill test before handover

    Fill test is done slowly with thorough checks of every flat below to confirm that no seepage has returned.

Landmarks of King Abdulaziz

King Abdulaziz sits between Khurais Road bounding it to the north and Al Ahsa Road from the south. Work is organised in relation to these major thoroughfares, and roof access is via the shared entrances of the residential blocks.

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

Tank seepage is blistering paint in the flat downstairs. How long does sealing take?
Waterproofing takes three to four days from drain to fill test. The affected flat below should be inspected a week after completion to confirm that seepage has stopped and damp is no longer entering.

Will vibration from the road reopen the new waterproofing?
Multi-layer flexible coatings absorb vibration far better than bare concrete or patched surfaces. The layers stretch and contract as the tank moves, while rigid patches crack and fail.

Do residents need to leave the building while the roof work happens?
No, residents can stay in their flats. Shared entrances and common areas may be briefly restricted, but individual homes remain open. Noise from roof work will be audible in upper-floor flats.

If a building has ten flats, who pays for the tank waterproofing?
This is agreed between the flat owners and the building management. If the tank is shared, costs are divided among the units. Clear agreement must be reached before work begins.

The tank is very old. Should I replace it instead of sealing it?
Replacement takes much longer and costs more than sealing. Waterproofing stops the leak immediately, and old tanks often remain in service for years afterwards.

After sealing, should the flat below install an extra water filter?
Waterproofing stops external dirt and damp from entering, but water itself may carry salts from old pipework. A simple filter at the flat's water inlet is sufficient.

How much does water tank waterproofing in King Abdulaziz cost?
It is set after we have seen the job, because the price follows the size of the place, its condition and the time the work takes. Send a photo and a description on WhatsApp and we will give you an estimate before we reach King Abdulaziz.
