Water tank waterproofing in Jabrah, Riyadh

Jabrah is one of Riyadh's historically and culturally significant districts in the city centre, home to the nineteenth-century Jabrah Mosque and the traditional Jabrah market, with a mix of residential buildings, apartments and villas around older narrow commercial streets. Tanks on rooftops of closely-set old buildings face variable pressure from simultaneous filling and draining, and hard water and groundwater accelerate erosion.

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 Jabrah

Tanks in Jabrah leak quickly because they sit on very old buildings, and repeated pressure accelerates erosion at a noticeable pace. The whole method is set out in the water tank waterproofing overview.

  • Very old buildings and eroded concrete

    Tanks on Jabrah's old rooftops were built decades ago, and the concrete holds deep erosion from chronic damp. Repeated filling and draining ruptures cracks and forces out salts, so sealing protects against the spread of existing erosion and loss.

  • Narrow lanes, markets and variable pressure

    The traditional markets and narrow commercial streets in Jabrah carry heavy foot and vehicle traffic, and constant vibrations and movement weaken fine cracks in tanks on old roofs. Cracks open and enlarge.

  • High groundwater and a nearby wadi

    Jabrah is close to Wadi Hanifah, and groundwater is high. Old buildings hold chronic ground damp in their foundations, so tanks on these roofs suffer damp from outside and inside. Sealing protects from both.

What's Included

An old densely populated district with narrow commercial streets and traditional markets, buildings are close-set and tanks sit on old roofs.

  • Emptied and fully dried

    Draining a tank on an old building's roof requires care not to stress the structure, and drying takes a long time.

  • Cracks and leak points surveyed

    Checking cracks and leaks in a very old tank focuses on deep erosion, widening seams and salt deposits.

  • Surface prepared before coating

    Cleaning the interior removes heavy salt deposits, bacteria, sand and mould completely.

  • Waterproofing applied in coats

    Applying coats to an old tank requires very long waiting between layers to ensure high strength and adhesion.

  • Full curing time

    Complete curing and drying is much longer for very old tanks because damp is deeply accumulated.

  • Fill test before handover

    Testing before filling includes thorough detailed checking of every crack, seam, corner and remaining deposits.

The character of Jabrah

Historic district: close-set buildings, narrow lanes and ageing services

Tanks in an old district like Jabrah sit on close-set buildings near each other, so a leak from one tank affects neighbours below, and sealing protects the neighbour from damp running into shared building fabric.

Questions before booking

Why do tanks in an old district like Jabrah leak faster?
Very old buildings hold tanks on roofs with eroded concrete, and repeated pressure and vibrations from traditional markets rupture cracks and send water through.

Is water safe to drink after the tank is sealed in Jabrah?
Entirely safe. After draining and cleaning all heavy deposits and bacteria, and applying drinking-water-approved material, the water is safe.

Can a very old tank (50 years) be sealed or must it be replaced?
An old tank can be sealed if the concrete is not completely eroded. We inspect it first and decide if sealing is enough.

Do vibrations from the crowded traditional markets affect the tank?
Yes. Heavy foot and vehicle traffic in narrow markets sends vibrations, and fine cracks open and enlarge.

Does high groundwater in Jabrah affect the quality of the sealing?
Yes. High groundwater requires longer drying time before filling, and sealing protects against external damp pressure.

After sealing, should the tank be checked yearly?
Yes. Annual checking is essential for old tanks in a historic district to confirm the sealing strength holds against repeated pressure.

How much does water tank waterproofing in Jabrah 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 Jabrah.
