Water tank waterproofing in Al Salihiyah, Riyadh

Al Salihiyah is an older residential quarter in central Riyadh holding multi-storey apartment buildings with shared entrances and narrow communal spaces between closely-spaced blocks. Tanks sit on building roofs and face variable pressure from simultaneous filling and draining across dozens of residential units, which accelerates cracks and seepage.

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 Salihiyah

Tanks in Al Salihiyah show rapid cracking because of constant and sharp pressure changes from different units using water at the same time. The whole method is set out in our full account of water tank waterproofing.

  • Simultaneous filling and draining from dozens of units

    An apartment block with a hundred units holds at least fifty small tanks or three large shared tanks, and simultaneous filling and draining from different units causes sharp, rapid pressure swings. Fine cracks open and close quickly and enlarge with each cycle.

  • Shared stairs, corridors and concentrated damp

    The old tiled stairs and corridors below tanks collect damp from leaks and constant cleaning, and the moisture weakens grout and moves into the building fabric beneath. Sealing stops leak-fed damp spreading under surfaces.

  • Older buildings and eroded concrete

    Concrete in tanks built fifty years ago carries internal erosion from chronic damp and repeated pressure cycles. Sealing protects against the spread of existing erosion and new cracks.

What's Included

A dense older apartment quarter in central Riyadh, tanks on rooftops face changing pressure from simultaneous filling and draining across many units.

  • Emptied and fully dried

    Draining a shared tank in an apartment block needs coordination with owners and residents, and water may be cut to part of the block temporarily.

  • Cracks and leak points surveyed

    Checking cracks and leaks in an old shared tank focuses on pressure cracks and deep erosion damage.

  • Surface prepared before coating

    Cleaning the interior of an old tank requires care to remove hard-water deposits, bacteria and sand completely.

  • Waterproofing applied in coats

    Applying coats requires long waiting periods between layers to build high strength against continuous variable pressure.

  • Full curing time

    Complete curing and drying is very sensitive in old tanks because of moisture in the surrounding building structure.

  • Fill test before handover

    Testing before filling includes thorough checking of every crack, seam and corner in an older tank.

The character of Al Salihiyah

Apartment district: residential blocks, repeated floors and shared entrances

Shared tanks in apartment blocks fill and drain from many units at different times, causing harsh variable pressure on the walls. Sealing protects against pressure-driven cracks and the seepage they produce.

Questions before booking

Why do apartment block tanks in Al Salihiyah leak faster than others?
Apartment blocks with dozens of units fill and drain at different times and simultaneously, so tank pressure swings rapidly and sharply. Fine cracks open, close and enlarge at speed.

Is water from a shared tank safe to drink after sealing?
Entirely safe. We drain the tank, remove all deposits and sand, apply drinking-water-approved material, and the water is safe for all units.

How is the sealing coordinated with all the apartment residents?
We plan with the building management or joint owners to drain at a set time. The work takes a few days, then the tank returns to service.

Does sealing the tank protect the shared stairs below from damp?
Yes. Full sealing stops leaks from the tank bottom, so no damp runs down onto the tiled stairs and corridors beneath.

If the tank is very old, can it be sealed or must it be replaced?
An old tank can be sealed if the concrete is not fully eroded. We inspect it first and decide whether sealing is enough or replacement is needed.

How often should a shared tank be checked after sealing?
A simple annual check is enough to confirm the sealing strength holds and no new cracks have appeared.

How much does water tank waterproofing in Al Salihiyah 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 Salihiyah.
