Water tank waterproofing in Al Sahafah, Riyadh

Al Sahafah is Riyadh's first vertical suburb, with tall residential towers where many flats share a single tank or more. A tank leak undermines the building's foundations and threatens apartments below it. Many towers here are ageing, and tanks carry heavy loads from continuous daily use across dozens of households.

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 Sahafah

Tanks shared among many flats in a single tower seep slowly, revealing themselves only through damp that appears on walls below, often weeks after the leak has started. The whole method is set out in our full account of water tank waterproofing.

  • The tall tower makes tank access difficult

    Lifts, stairs and narrow hallways in a residential tower make moving equipment and materials to a high roof a matter of careful coordination. Work above an occupied building demands timing that suits the residents and protection so damp does not drip onto flats below.

  • Shared tanks divide responsibility among many

    A tower with dozens of flats may need one or two tanks. A small leak in the tank shows as damp in the lower flats, and each household suspects the others. The seal must be complete so the problem does not return after agreement among many owners.

  • Old concrete cracks from constant vibration

    Al Sahafah towers are among Riyadh's oldest, with concrete now more than twenty five years old. Vibration from vehicle movement and lifts running constantly opens fine cracks in the tank. The waterproofing must penetrate these cracks to seal them permanently.

What's Included

Tall apartment blocks in Al Sahafah require workers and equipment to pass through narrow shared entrances, stairs and lifts up to roofs several storeys high.

  • Emptied and fully dried

    Tanks shared among dozens of flats need to be drained fully, and coordination with neighbours is necessary so water does not suddenly vanish for someone who was not told.

  • Cracks and leak points surveyed

    Older towers hold fine cracks that appear from vibrations over many years, and each one must be found before work starts.

  • Surface prepared before coating

    The roof surface may be wet from rust, grime and algae buildup, and deep cleaning is necessary before any waterproofing is applied.

  • Waterproofing applied in coats

    Coating layers are applied with care on concrete this old, filling the pores and fine cracks that have formed over decades.

  • Full curing time

    Curing takes several days on a tower because the surface is large and internal moisture needs time to leave completely.

  • Fill test before handover

    Testing by filling the tank happens slowly so sudden pressure does not stress the new seal.

The character of Al Sahafah

Apartment district: residential blocks, repeated floors and shared entrances

Multiple flats in one tower mean a small leak affects dozens of families, so sealing is not optional but necessary. Coordination with neighbours and building management is part of the solution. The tank must be safe for drinking water for all the flats it serves.

Questions before booking

The tank serves dozens of flats: will water be cut to all of them?
Yes, the tank must be drained completely and allowed to dry before work begins. In an occupied tower this must happen within set days. We agree with the building management on when to work so residents are not surprised.

Is the damp in the ground floor flat coming from our roof tank?
If damp sits directly under the tank and spreads down the walls, it usually comes from the tank. Damp from air conditioning or other pipes shows a different pattern. An inspection of the tank reveals which it is.

After sealing the tank, how long until damp vanishes from the flat wall?
After sealing and refilling, damp begins to fade within days, but the wall itself may need two weeks to dry completely, especially if moisture has worked deep into the concrete.

The lift is narrow and equipment is heavy: does this delay the work much?
Residential towers need special planning. We disassemble heavy equipment and carry it up in stages, or use alternate routes. This does not delay work greatly, but needs careful planning first.

A neighbour says their tank is also leaking: must we seal both at once?
If the tanks are separate, one can be sealed before the other. If they are connected or share piping, sealing both together may work better. All this is agreed beforehand with those involved.

Must we tell all the residents before sealing the tank?
Yes, because water will be cut to every flat. Coordination with building management or the residents' council is essential. We choose a time that suits most households.
