Water tank waterproofing in Al Wusaita, Riyadh

In Al Wusaita apartment blocks share a single tank across multiple units, and a leak in one tank sends damp through the walls of the entire building. We seal the tank from the inside so the water stays contained and moisture does not seep down to lower floors, protecting every flat at once.

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 Wusaita

A seeping tank in one building means multiple flats reporting wall damp at the same time, not just one unit isolated on a single floor. The whole method is set out in our notes on water tank waterproofing.

  • One tank serves multiple floors in the building

    A single shared tank fills flats on the first, second and third floors together. A small leak travels down through the shared walls and affects every resident. Sealing must protect the entire tank, not just patch one flat or one floor.

  • Water pressure drives cracks wider

    In apartment blocks, the tank fills to capacity more often than in villas, and the pressure on the tank walls is greater. Small cracks that might hold in a villa tank open faster under the repeated filling cycles of a shared apartment tank.

  • Damp rises and falls through shared walls

    A flat on the third floor and the flat directly below both complain of damp at the same moment. Sealing the tank at source stops moisture entering the walls, so all affected residents see the walls dry out together.

What's Included

The residential blocks in Al Wusaita were built over different decades, and older tanks develop cracks that worsen under the weight of water in hot seasons and with the pressure of repeated refills.

  • Emptied and fully dried

    Emptying a tank in a shared building requires coordination with the flat owners, and the drained water is removed without affecting the units on lower floors.

  • Cracks and leak points surveyed

    Cracks in tanks in Al Wusaita often appear at corners where walls meet the base, and they start small but grow under repeated filling and seasonal pressure.

  • Surface prepared before coating

    The inside surface of a shared tank needs deep cleaning before waterproofing, because deposits and sediment prevent the coating from bonding properly to the concrete.

  • Waterproofing applied in coats

    The sealant is applied in multiple coats to the walls, with each layer drying fully before the next one, ensuring protective depth against the constant pressure of the stored water.

  • Full curing time

    A sealed tank needs the full curing time before it is filled again, and this waiting period is essential so that the seal does not rupture when water enters under pressure.

  • Fill test before handover

    The fill test is carried out slowly and carefully to confirm that the waterproofing holds across every joint and wall, and any small seepage found is repaired before the tank is handed over.

The character of Al Wusaita

Apartment district: residential blocks, repeated floors and shared entrances

In a multi-storey apartment block, one leaking tank means shared walls growing wet and every resident feels it at once. Sealing the tank from inside protects the entire building's investment in construction.

Questions before booking

Can you seal the tank while other flats are occupied below it?
Yes. The drainage and sealing happen without cutting water to the other units. We test the tank after waterproofing before it goes back into service, so other flats are never left without supply.

If two flats have damp, who pays for the tank sealing?
The tank is shared, so waterproofing is a shared responsibility. Usually the residents agree to split the cost based on their share of the tank and usage across the building.

How long are the flats without water during sealing?
We drain and seal the tank in one day typically. After sealing finishes and the fill test passes, the tank returns to service and water reaches the flats as normal.

Is the damp worse in the flat directly under the tank?
Yes, the flat directly below the tank is affected most. However damp can travel down the shared walls through several floors, so sealing protects all residents across the building.

Are tanks in Al Wusaita apartment blocks old or relatively new?
The age of the buildings varies widely. Older tanks need waterproofing sooner, while newer tanks may benefit from preventative sealing before problems start.

After sealing, do the damp walls dry out immediately throughout the building?
The leak stops at once, but damp in the walls needs time to dry fully. Good ventilation speeds up the drying process over weeks after the leak is stopped at source.

How much does water tank waterproofing in Al Wusaita 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 Al Wusaita.
