Tank leak repair in Al Nuzhah Jeddah
Al Nuzhah is a mixed-character district in northern Jeddah with old villas, apartment blocks and commercial buildings, and tank ages and types vary widely. Old villas have welded metal tanks sitting overhead, newer buildings have large underground concrete cisterns. A leak here may come from rust in old metal, cracks in concrete, or pipe entry points.

Why the job is different in Al Nuzhah
Old villas in Al Nuzhah are thirty years or older, with metal tanks showing rust at edges and seams, while newer buildings have reinforced concrete cisterns. The method is set out in full on the full Tank leak repair page.
Old metal tanks in villas and rust corrosion
Villas built in the 1970s and 1980s have old welded metal tanks overhead. Rust begins at corners, seams and rivet points, and solar heat accelerates it.
Pipe entry points and slow seepage
In villas and buildings, pipes enter the tank from below or the side. The entry point rusts or cracks under vibration, heat and pressure, and the leak is so slow that owners notice it only after weeks or months.
Underground cisterns in buildings and concrete cracks
Modern buildings and hotels in Al Nuzhah have large underground cisterns buried beneath floor slabs. Cracks develop from differential settlement, groundwater pressure or concrete age.
The character of Al Nuzhah
Mixed district: shops at street level with homes above them
Al Nuzhah is a mixed district with old villas and modern apartment and commercial buildings. Old villas have old welded metal tanks overhead that require precise repair, while modern buildings have large underground cisterns beneath slabs. Repair methods and technology differ greatly between the two types.
Where the water leaves decides how it is repaired
A mixed-use quarter in northern Jeddah between Madinah Road and Prince Majid Road, with King Fahd Road running through it. Villas, apartment buildings and commercial shops are distributed at moderate density, and the district is known by Sultan Bin Salman Street, Mall of Arabia and the Sixtieth Street junction.
Damp and salt on the outside wall
Fine cracks and small holes in the base of old metal tanks begin from corrosive rust eating through old metal.
The kind of crack
Slow seeping from valve seats and welds that allow water to escape very gradually, visible as a damp patch beneath the tank.
The wall to floor junction
Pipe entry points and the pipes themselves entering from below or the side, with rust beginning at the entry and pressure widening the crack.
Pipe entries
High humidity and continuous solar heat accelerate rust and cracking, and the district is close to the coast so moisture is high.
The condition of the old lining
Underground cisterns are buried beneath floor slabs and soil around the tank may be damp or alkaline, accelerating corrosion.
What the tank is made of
Sudden large leaks may indicate a break or separation at the entry point, while slow leaks may mean gradual rust or a very fine hairline crack.
How we work
-
1
Inspect and locate the leak
We close the float valve and the outlet, mark the water level and watch it fall, then check the fittings and the wall beside it. That separates a tank leak from a pipe leak or a float valve that never shuts.
-
2
Drain, clean and dry
We empty the tank, lift the sediment off the base, wash back to sound concrete and let the surface dry. No repair holds on a damp or dusty face.
-
3
Repair the cracks and the entries
We cut the crack open, fill it with a non-shrink mortar, inject anything still weeping and rebuild around the pipe sleeve. A joint that moves takes a flexible detail, not a rigid one.
-
4
Refill, test, then sterilise
We refill, read the level again to confirm the drop has stopped, then sterilise before the water is used, because the tank has been open with tools and hands inside it.
What tank leak repair includes
-
A marked level test
A reading before and after with everything shut, which establishes that the loss is the tank and not the plumbing.
-
Draining and sediment removal
Water and silt out of the base, so the floor and the walls can be seen as they really are.
-
Pressure wash and dry back
The weak layer and the dust come off, because a repair only holds on sound concrete.
-
Cracks opened and filled
The crack is cut open and filled with a non-shrink mortar, and anything still weeping under water pressure is injected.
-
Refill and a recorded test
We refill, read the level again and write the reading down, so the result is not a matter of opinion.
-
Sterilised and back in service
A wash and a sterilisation once the material has cured, and guidance on running the first fill off before the water is used.
What is different about Airport Sub-Municipality
The Airport sub-municipality covers some of the oldest established districts of northern Jeddah, gathered around King Abdulaziz International Airport between Madinah Road, King Fahd Road and Prince Majid Road. The stock is villas, single family houses and apartment blocks built decades ago, many served by ageing water and sewer lines. Commercial streets such as Quraish, Sari and Sultan bin Salman are lined with restaurants, furnished flats and popular markets. Dense commercial kitchens, worn pipework and the gaps in older buildings give cockroaches and rodents steady food and shelter, and the high resident population keeps that pressure constant through the year.
Questions about this district
How do I know if the leak is in the tank itself or in the external pipes?
Close the float valve and the outlet and watch the level fall. If it drops, the leak is in the tank. If it stays stable, the leak is in the external plumbing.
Is cleaning the tank of rust enough, or must we repair it?
Cleaning alone is not enough. If there is a hole or crack, we must repair the rupture before any lining.
Do old metal tanks in villas need lining?
Lining comes after repair. If a metal tank is rusty but not leaking, we may recommend lining to prevent future rust.
What is the difference between a leak in a metal tank and a concrete one?
A metal tank rusts and thins, concrete cracks from pressure and heat. Repair methods differ for each.
Why is the pipe entry point the most common leak location?
The entry point bears concentrated pressure and heat causes expansion and contraction. The weld corrodes or the pipe pulls free slightly.
Do underground cisterns beneath floor slabs need the building torn open?
If the leak is minor, we may repair it internally through a small access. If it is large, we may need to open part of the floor.
How much does tank leak repair in Al Nuzhah cost?
It is set after the inspection, because the price follows the type of infestation, the size of the space, how far it has spread and the number of visits it needs. Send a photo and a description on WhatsApp and we will give you an estimate before we reach Al Nuzhah.
