Water tank waterproofing in Al Jaradiyah, Riyadh

Al Jaradiyah is an old apartment district in west-central Riyadh with a history spanning decades, marked by an old railway stop nearby. Tanks are scattered across mid-rise blocks of varying age. Hard water, thick limestone scale and deep cracks in old concrete make sealing essential. Leaks lose stored water and spread damp across multiple flats and neighbouring buildings.

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 Jaradiyah

Al Jaradiyah is an old neighbourhood where tanks show multiple deep cracks and thick limestone deposits that form fast. The whole method is set out in the water tank waterproofing overview.

  • Older buildings with tanks of varied age and wear

    Al Jaradiyah holds blocks from the 1950s and 1960s, and their old concrete tanks have lost original strength. Some tanks may be sixty years old or more, with brittle concrete that cracks easily. Limestone scale has built up on inner walls and weakened them further.

  • The old railway stop and decades of vibration history

    The old railway stop beside the district may no longer run heavy traffic, but past vibrations may have set deep cracks into the old concrete itself. These cracks are foundational, not surface, and cannot be repaired easily from outside. Interior sealing may be the only solution because deep structural cracks resist external repair.

  • Seepage affecting multiple floors and neighbouring buildings

    Al Jaradiyah is crowded with buildings standing close, and damp from one tank may travel to an adjacent building through shared walls. Residents may not realise the leak originates in the neighbouring block, and each may patch his own wall without treating the real source.

What's Included

An old apartment district in west-central Riyadh with mid-rise buildings of varied age, where tanks are older and more prone to cracking.

  • Emptied and fully dried

    Draining in Al Jaradiyah may involve old buildings needing special handling. Coordination with residents takes time because some may not see the urgency of sealing.

  • Cracks and leak points surveyed

    Cracks are multiple and deep in old tanks; thorough detection reveals scattered seepage points hidden under limestone deposits. Full documentation is needed before cleaning starts.

  • Surface prepared before coating

    Removing thick limestone scale is hard work because water is hard and deposits are heavy. Complete scale removal is essential for coating to bond properly.

  • Waterproofing applied in coats

    Coating may need extra preparatory layers because old concrete may be loose or flaking. Full surface prep may take longer than modern tanks require.

  • Full curing time

    Full drying takes time because old concrete holds moisture longer. High humidity in the district may slow natural evaporation further.

  • Fill test before handover

    Testing during fill may reveal new seepage points not caught in initial inspection, requiring extra work before handover.

The character of Al Jaradiyah

Apartment district: residential blocks, repeated floors and shared entrances

An apartment district means tanks serve buildings with shared entrances and repeated floors. Scale and cracks in old tanks may be deep, and damp may travel between adjacent buildings through shared walls. Getting agreement from many residents in an old district can be challenging.

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

Do old Al Jaradiyah tanks need deeper inspection before sealing?
Al Jaradiyah tanks are sixty years old or more, requiring specialised inspection. Fine and deep cracks are mixed, and limestone deposits may hide leak points. Thorough survey often reveals seepage spots not obvious on first observation.

Did historical railway vibrations permanently weaken the tank?
The old railway stop may no longer run heavy traffic, but past vibrations may have set foundational cracks into the concrete. These deep cracks resist repair from outside; interior sealing is the answer.

Can weak concrete be repaired before sealing, or is coating enough?
Weak concrete in Al Jaradiyah may need preparatory treatment. Coating alone may not hold if concrete is loose or flaking. Extra preparation or primer coats may be needed before the final seal layer.

Can seepage from a neighbouring building enter my flat?
In a crowded district like Al Jaradiyah, shared walls can carry damp from one building to another. The leak may appear in your flat while originating in the neighbouring tank. Coordinating with neighbours may be necessary.

Is sealing an old tank more expensive than sealing a new one?
Old tanks may need extra preparation and additional coats, raising cost. But the benefit is greater because an old tank is far more likely to leak if left unsealed.

Is there a way to prevent shared seepage between neighbouring buildings?
Interior tank sealing stops leaks from that unit. If seepage originates from a neighbouring building, separate repair outside your flat may be needed, such as repairing the external wall.
