Water tank waterproofing in Al Malaz, Riyadh

Al Malaz is an old district in central Riyadh built as government housing in the era of King Saud. Its buildings and apartments date back decades, and major roads carry heavy traffic that coats facades in grey exhaust film. Old tanks here leak slowly, and the moisture they produce travels through shared walls and damages old tiled stairs and passages that were built for a different era.

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 Malaz

Tanks in Al Malaz are very old and often begin to leak after 30 to 40 years of use, and moisture travels quickly between tightly built adjacent buildings. The whole method is set out in our water tank waterproofing guide.

  • Old tanks leak gradually and moisture spreads to neighbours

    Al Malaz is an old district and its tanks are the oldest. Fine cracks start after decades and send moisture through shared walls to neighbouring homes. Sealing stops this spread and protects all surrounding buildings from accumulated damp.

  • Car exhaust makes buildings worse off than moisture alone would

    Heavy traffic on surrounding roads coats facades in grey soot. Tank moisture works with this soot and speeds wall and grout decay. Sealing reduces moisture and lowers the total stress on the building.

  • Old tiled stairs and passages trap moisture for months

    Stairs and passages in Al Malaz are old and grout joints are already worn. Tank moisture enters these confined spaces and causes more decay and deterioration. Sealing reduces the moisture that enters these areas.

What's Included

Heavy traffic on main roads coats facades in grey exhaust film, and old tiled stairs and passages show scale deposits from hard water and worn grout joints that decay steadily.

  • Emptied and fully dried

    Complete drainage of an old tank may be complex because mineral deposits from decades may be trapped, so thorough deep cleaning is needed first.

  • Cracks and leak points surveyed

    Cracks in very old tanks are multiple and interconnected, and detailed inspection takes considerable time to find all of them.

  • Surface prepared before coating

    Surface preparation in an old tank means thorough cleaning of deposits built up over decades before any coat can be applied.

  • Waterproofing applied in coats

    Coats are applied slowly to old tanks because the old structure may not tolerate rapid application or heavy pressure.

  • Full curing time

    The full curing period may be longer because an old tank needs extra care and slower processing than a newer one.

  • Fill test before handover

    Testing before handover must be precise because an old tank may not tolerate any errors or shortcuts.

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

What is the typical age when an old tank begins to leak?
Tanks in Al Malaz are 50 to 60 years old in many homes. After 30 to 40 years, cracks start to appear and slow leaks begin.

If the tank is leaking, does it affect my neighbours in Al Malaz?
Yes, severely. Moisture travels through shared walls and foundation gaps, and neighbours may see damp patches in their homes before you notice the problem.

Is water safe to drink after the tank is sealed in Al Malaz?
Yes, the material is safe for drinking water. Water becomes cleaner because the sealed tank no longer allows dirt and dust to enter through cracks.

How long must you wait before filling the tank after sealing in Al Malaz?
At least three to five days for the material to cure fully. Humidity in central Riyadh is high, so this may take longer than in other areas.

Can a very old tank (50 years) still be sealed safely?
It depends on the tank's condition. Inspection determines whether the walls are strong enough to hold the sealing material.

Does sealing the tank preserve the value of an old house?
Yes, it preserves the home's health and reduces visible damp damage. This maintains property value over time.

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 Malaz.
