Water tank waterproofing in Al Sulay, Riyadh

Al Sulay is an industrial zone with warehouses, showrooms and workshops alongside residential villas and flats. Oily grime from shops, diesel soot and soil from unpaved yards build up on tanks faster here than anywhere else in the city.

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 Sulay

Tanks here are covered in a grey oily film from industrial grime, diesel soot and exhaust, which accelerates material breakdown and leaking. The whole method is set out in the water tank waterproofing overview.

  • Oily grime and soot speed up material breakdown

    Nearby workshops and warehouses deposit oily residue and diesel soot on rooftops. This layer affects tank materials chemically, not just physically. Sealing must withstand this chemical attack.

  • Unpaved yards and desert sand spread together

    The wide yards around shops and warehouses are not paved, so heavy machinery and lorries kick up sand. Sand travels with the air and lands on roofs, mixed with oil and dust.

  • Lorry traffic and vibration pressure the tank

    Al Kharj Road and the ring road carry heavy lorry traffic all day. Vibration stresses tanks and speeds up crack formation. Sealing protects not just against moisture but against mechanical pressure too.

What's Included

Warehouses and an industrial zone surround the district, and the ring road carries constant lorry traffic and heavy machinery movement.

  • Emptied and fully dried

    Draining removes water that may carry oily deposits and soot from the polluted roof surface.

  • Cracks and leak points surveyed

    Inspection focuses on every tiny crack that might let industrial grime enter the tank.

  • Surface prepared before coating

    Cleaning is intense, removing all oily deposits, mould and algae before sealing starts.

  • Waterproofing applied in coats

    Coats are applied with great care to ensure long term resistance to chemical grime.

  • Full curing time

    Drying may take extra days because of moisture and deep oily residue in the pores.

  • Fill test before handover

    Testing is strict: we wait 48 hours before confirming it is ready for use.

Landmarks of Al Sulay

Work is reached easily via Shibh Al Jazirah Street running through the district, and Istanbul Street leading directly to tanks. Mohammed bin Mandour Mosque nearby helps locate the work site.

What is different about South Riyadh

South Riyadh is the older, denser and more industrial side of the capital. Manfuhah, Al Shifa, Al Aziziyah, Al Dar Al Baida and Al Faisaliyah are closely built low rise blocks and small villas with shops, workshops and warehouses between them, the wholesale vegetable market sits in Al Aziziyah, and the industrial city and Al Kharj Road carry lorry traffic all day. Oily grime from workshops, diesel soot and soil from unpaved yards build up on ground floors, entrances and tiled floors faster than anywhere else in the city.

Questions before booking

Do oily deposits from nearby workshops get into the tank and pollute the water?
Yes, oily residue and soot settle on roofs and enter tanks through cracks. This affects water taste and smell. Sealing closes the cracks, so these deposits cannot enter.

Is soil from unpaved yards in the industrial zone harmful to the tank?
Yes, soil enters with water and builds up at the base. Soil mixed with oil causes rapid corrosion of the tank's inner surface.

Do vibrations from heavy lorries cause the tank to leak?
Yes, continuous vibration speeds up crack formation in older tanks. A small crack can worsen quickly under constant vibration stress.

Is the water safe to drink in Al Sulay once the tank is sealed?
Yes, after sealing and full cleaning, water is safe to drink. Materials are approved for use with drinking water.

How often does the tank need cleaning from industrial grime after sealing?
After sealing, one annual outside inspection is enough. No inner cleaning is needed if the seal is intact.

Can the sealing materials handle industrial chemical grime?
Yes, materials are approved to withstand harsh industrial conditions, including oily grime and exhaust.
