Water tank waterproofing in Al Nadwah, Riyadh

Al Nadwah faces the open desert and the sand belt of the Dahna, taking the first and heaviest share of every dust storm. Fine sand drives into tanks through cracks and ventilation, and seepage here carries sand and grit that cause ongoing damage. Waterproofing stops sand entering and protects water quality where it matters most.

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 Nadwah

Dust storms from the Dahna blow fine sand into cracks in tanks, polluting the water and speeding up the spread of existing damage in the concrete. The whole method is set out in our notes on water tank waterproofing.

  • Fine sand from the Dahna enters the tank

    Dust storms from the Dahna hit Al Nadwah hard, and fine sand enters the tank through ventilation holes and small cracks. The sand pollutes the water and creates rust that speeds up crack growth. Waterproofing seals these openings and protects the water from contamination.

  • Seepage carries sand and grit into the building

    In a mixed district a slow leak may seem minor, but it seeps away carrying storm sand and debris. This settles in the areas below the tank and enters the apartments and shops underneath with damp and grit. Sealing stops this spread.

  • Ground floor shops suffer damp laden with sand

    Tanks above commercial shops may seep water heavy with sand and grit. This enters the shop walls and ruins stock and fittings. Full waterproofing protects the shop from contaminated damp.

What's Included

An eastern Riyadh district close to Al Janadriyah and An Nazim with a mix of apartment blocks and villas with private gardens, facing the open desert and severe dust storms.

  • Emptied and fully dried

    Draining the tank in Al Nadwah is done carefully to dispose of sand and grit that has built up from past storms without spreading it onto the street.

  • Cracks and leak points surveyed

    Tank inspection reveals cracks that sand has entered through and the deposits covering them that hide the real extent of the damage.

  • Surface prepared before coating

    Surface preparation includes removing accumulated sand, grit and lime scale that covers the real cracks underneath.

  • Waterproofing applied in coats

    Waterproofing coats are applied to seal small cracks and ventilation openings and prevent sand and grit entering from dust storms.

  • Full curing time

    Full curing takes adequate time to make sure the coats cover every crack and opening where sand can blow in during the next strong wind.

  • Fill test before handover

    The fill test confirms the tank is sealed properly and does not allow sand or grit to enter through any small opening.

What is different about East Riyadh

East Riyadh runs from King Abdullah Road and Khurais Road out past the eastern ring road towards Al Janadriyah. Al Rawdah, Al Naseem and Al Yarmuk are established districts of villas and mid rise apartment blocks, while Al Rimal, Al Munsiyah and Ishbiliyah are newer estates with more compact houses and lighter finishes. This side of the city faces the open desert and the sand belt of the Dahna, so it takes the first and heaviest share of every dust storm, and fine sand works into stairwells, balconies and window tracks all along the Dammam highway.

Questions before booking

Does fine sand from Dahna dust storms enter the tank through the vent easily?
Yes. Very fine sand from the storm finds its way in through ventilation holes and small cracks. Waterproofing seals these openings and stops sand and grit entering the water.

Does seepage from an Al Nadwah tank actually pollute the water with Dahna sand?
The seepage does not pollute the water directly, but it allows storm sand to enter through the cracks. This reduces water quality and the sharp sand particles speed up crack growth.

Do ground floor shops in Al Nadwah suffer more than upper flats from contaminated leaks?
Yes. Shops directly under tanks face damp laden with sand and grit. This ruins goods, floors and walls much faster than it affects upper floor homes.

How often must a tank be cleaned of sand and grit after a heavy dust storm?
After a strong dust storm a tank may need cleaning to remove sand that entered. But waterproofing reduces the amount of sand that can get in by a large margin.

Does water stay clean from sand after sealing even through a bad dust storm?
Yes. Sealing closes the openings where sand enters. Water stays clean even through dust storms if the tank is properly sealed.

Should a tank that collected heavy sand buildup be replaced instead of sealed?
Sealing is enough if the tank walls are sound. Inspection determines whether the walls are weak, and waterproofing protects against new sand entering.
