Water tank waterproofing in Al Sinaiyah Al Qadimah, Riyadh

Al Sinaiyah Al Qadimah is an old industrial quarter where heavy trucks move constantly and machines vibrate the ground throughout the day. Tanks here face mechanical stress that simply does not exist in ordinary residential neighbourhoods, and slow leaks begin in hairline cracks that widen with every vibration cycle.

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 Sinaiyah Al Qadimah

Tanks in workshops and warehouses leak more quickly than tanks in homes, because vibration repeatedly opens small cracks and accelerates water loss over time. The whole method is set out in our water tank waterproofing guide.

  • Truck vibration widens cracks steadily

    The constant movement of heavy vehicles on the wide streets sends vibrations into the tanks and their foundations. A small crack grows with each vehicle that passes, and waterproofing from inside stops this accelerating seepage before it destroys what sits below the tank.

  • Warehouse and workshop tanks are larger

    Industrial facilities and storage warehouses need much larger tanks than a standard villa. A big tank carries more weight and higher pressure on its walls, so cracks leak faster. Sealing from inside supports the walls against pressure and stops major water loss at its source.

  • Damp ruins equipment and stock

    A leak from a workshop or warehouse tank means moisture spreading through the building and damaging equipment, tools and stored goods. Water running from a crack leaves a large damp patch, and complete interior sealing protects everything around the tank from deterioration.

What's Included

The old industrial zone has wide straight streets built for heavy truck traffic, and the tanks rest on foundations that are subject to continuous vibration from the movement of vehicles and machinery across the quarter.

  • Emptied and fully dried

    Warehouse and workshop tanks hold far more water than a villa tank, so draining takes longer and drying requires powerful ventilation to remove moisture from the concrete.

  • Cracks and leak points surveyed

    Cracks in old industrial tanks run deep and numerous because of constant vibration, so we inspect each one carefully before selecting the coating material and technique.

  • Surface prepared before coating

    The inside surface needs heavy cleaning to remove scale deposits and white mineral layers before preparation, and may need local grinding on large cracks to ensure the coating bonds.

  • Waterproofing applied in coats

    Application requires thicker coats in industrial settings because the pressure on the tank walls is higher than in residential tanks, so the seal must be proportionally stronger.

  • Full curing time

    Curing takes longer in workshop areas because vibration from nearby machinery can disrupt the drying of each coat, so we recommend shutting down machinery at night during the hardening period.

  • Fill test before handover

    Testing includes filling the tank slowly and watching for any seepage in the first two hours, because deep cracks may only show under the full weight of water pressure.

The character of Al Sinaiyah Al Qadimah

Industrial area: workshops, warehouses and loading yards

An old industrial area means tanks sitting on foundations that face constant vibration. Sealing from inside reinforces the walls against pressure and repeated movement from trucks and machinery passing throughout the day.

Landmarks of Al Sinaiyah Al Qadimah

Tanks in Al Sinaiyah Al Qadimah lie scattered between King Faisal Road where heavy trucks pass constantly and Al Kharj Road that bounds the zone to the south. We reach each site via the wide streets engineered for heavy vehicle traffic across the quarter.

Questions before booking

Does vibration from trucks actually crack the tank?
Yes. Tanks mounted on ordinary foundations move slightly each time a heavy truck passes nearby. Repeated movement widens hairline cracks. This is why leaks are far more common in industrial zones than in residential neighbourhoods.

Is an old workshop tank worth sealing or should it be replaced?
An old tank is worth sealing if the concrete structure itself is sound. We drain it fully and inspect the cracks carefully. If the cracks are surface damage we seal from inside. If they run deep through the wall, we advise replacement.

After sealing, is the water safe for industrial use in the workshop?
Yes, the waterproofing material is approved for stored industrial water. However, if the workshop also needs drinking water, discuss that need with us before we arrive so we confirm the product is right for that use.

Can you seal a very old factory tank without stopping production?
No. We must drain the tank completely and dry it before starting. This means the factory will be without water for a few hours. Coordinate with your team on a suitable time window for the work.

How often does a workshop tank need inspection after sealing?
After sealing, a standard tank needs a yearly inspection. However, in industrial areas with continuous water demand, watch for new seepage signs every six months because vibration can affect other cracks later.

Does dust and oil vapour from workshops enter the tank and affect the seal?
Grime does not harm the waterproofing material itself. Before sealing we clean the tank thoroughly of all deposits and scale. After sealing, fit a cover over the fill opening to stop dust and oil spray from the surrounding workshops entering the tank.

How much does water tank waterproofing in Al Sinaiyah Al Qadimah 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 Sinaiyah Al Qadimah.
