Water tank waterproofing in Al Dubiyah, Riyadh

Al Dubiyah is a small old residential quarter in south-central Riyadh; mid-rise apartments in closely packed buildings, their tanks buried underground between narrow walls. Heavy traffic on main roads around the district coats everything in grey exhaust, and the hard water in the tank leaves white mineral scale on the inside walls. These white patches hide the real cracks beneath.

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 Dubiyah

The hard water in Al Dubiyah deposits white scale on tank walls, hiding cracks underneath. Cracks are hard to see beneath the mineral coating. Old tanks here seep more than any other district. The whole method is set out in the details of our water tank waterproofing service.

  • Hard water and mineral deposits

    Water in Al Dubiyah is very hard. White deposits coat the tank's inside walls and hide cracks behind them. Cleaning must be deep before waterproofing to find the real cracks. The waterproofing material must withstand hard water without reacting to it.

  • Underground tanks trapped between old walls

    Tanks in Al Dubiyah are buried between old foundations. Draining is hard and access is tight. Moisture around the tank may come from old rain or neighbour's drainage. Inside sealing must be perfectly tight.

  • Old district and main roads nearby

    Main roads around Al Dubiyah carry heavy traffic. Grey exhaust deposits on every surface. Polluted air may affect waterproofing quality. Good ventilation during application is essential.

What's Included

Al Dubiyah is an old district in central Riyadh within the historic Al Dahu cluster. Roads are narrow, apartments are adjacent, and tanks sit underground surrounded by old foundations and tight pipes.

  • Emptied and fully dried

    Draining an old underground tank requires strong pumps and the water may be heavy with deposits.

  • Cracks and leak points surveyed

    Cracks are hidden under white mineral scale, so cleaning must be very deep to find them.

  • Surface prepared before coating

    The surface is fouled from years of use; cleaning takes hard scrubbing and light grinding of heavy scale.

  • Waterproofing applied in coats

    Coats go on old walls that may be damp, so complete drying before application is essential.

  • Full curing time

    Curing may slow because moisture around the old underground tank may affect drying.

  • Fill test before handover

    Fill testing is cautious because the old tank may not handle full pressure fast.

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

White patches on the tank: are they seepage or just mineral scale?
The white is mineral deposit from hard water. It hides cracks beneath. Draining and close inspection reveal the real cracks. The deposits may seal small gaps, but water may still find its way gradually.

The tank is underground and damp appears above it in the apartment: is it from the tank or from water around the foundation?
Inspection shows the source. If the tank is cracked and seeping, the leak comes from inside. If water comes from the sides and bottom, it may be from pooling water around the foundation.

The district is old and the tank is old: is sealing enough or must the tank be replaced?
Close inspection decides the tank's condition. If the tank's body is sound and cracks are surface, sealing works. If the tank is very weak, replacement may be better.

Does hard water affect how well the waterproofing works?
Slightly. Hard water may deposit on the sealing material, but approved material does not react to it. Deep cleaning before application removes old scale and lets the seal grip better.

The apartment sits above the underground tank: must I dry the foundation after sealing?
Yes, possibly. Old moisture in the foundation takes time to dry. Good ventilation and fans help. Dampness may continue for weeks after sealing.

How often should I inspect the tank after waterproofing in an old district?
First inspection one year after sealing. Old tanks may develop new cracks. Annual inspections afterwards help catch any problems early.
