Tank leak repair in Harat Al Sham Jeddah
Harat Al Sham sits in the northern part of the old quarter near Bab Al Madinah, with tall coral stone buildings carrying large roof tanks. Buildings here are taller than elsewhere in the old city and tanks bear higher water pressure. Leaks here may be more severe and faster because pressure is higher and tanks hold large volumes.

Why the job is different in Harat Al Sham
Tanks in Harat Al Sham are large and bear high water pressure, and leaks around entry points are common because pressure widens fine cracks. The method is set out in full on what Tank leak repair involves.
Large tanks under very high water pressure
Tanks here are larger and serve very tall buildings. Water pressure on tank walls is very high and fine cracks widen quickly under load.
Wide, old piping in very thick stone walls
Pipes here are larger and ancient, cast from very old iron. Thick stone walls protect pipes from sun but moisture and salt penetrate and cause deep rust.
Multiple entry holes on the tank and difficult access
Large tanks have many holes for overflow, outlet, air vent and cleaning. Each hole is a weak point, and some are very hard to reach because the tank sits in the middle of the limited roof.
The character of Harat Al Sham
Historic district: close-set buildings, narrow lanes and ageing services
Harat Al Sham is an established historic quarter with tall buildings and large tanks under very high water pressure. Repair requires understanding high pressure and large tanks, limited roof access and preservation of historic stone walls and heritage houses.
Where the water leaves decides how it is repaired
Harat Al Sham is a historic northern quarter inside the wall near Bab Al Madinah, holding old houses such as Dar Al Zahid, Banaja House, Dar Al Sarti and Ribat Al Khunji Al Kabeer, with high stone roofs and decorative wooden rawashin screens.
Damp and salt on the outside wall
The inlet hole from the mains or lower tank is exposed to very high pressure, and cracks around it have widened under load.
The kind of crack
The outlet and overflow holes suffer from rust and pressure, and are common leak sources.
The wall to floor junction
The tank body, whether iron or concrete, cracks under high pressure and thermal cycling.
Pipe entries
Moisture and salt penetrate thick coral stone and cause deep rust on pressurized metal pipes.
The condition of the old lining
Tank bottom and walls are covered in sediment, salt and rust from high pressure, full cleaning required.
What the tank is made of
Slow leaks around multiple holes go unnoticed but moisture appears on the roof or lower walls.
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 Historic Jeddah Municipality
The Historic Jeddah municipality covers the quarters of Al Balad inside the old wall: Al Mazloum, Al Sham, Al Yaman and Al Bahr. The buildings are tall houses of coral limestone and timber rawashin, centuries old, standing shoulder to shoulder on narrow lanes that see little sun, many under restoration or partly vacant. The ground is low and close to the sea and the harbour, humidity stays high through the year, and popular souqs and eateries trade late into the night. Old timber, voids between walls and goods stores create conditions favoured by termites, cockroaches, rodents and wood boring beetles.
Questions about this district
Is high water pressure the cause of leaks in Harat Al Sham?
Yes, pressure widens fine cracks in old tanks and pipes. Pressure leaks are faster and more severe.
Does cleaning the tank help stop a leak?
Cleaning removes sediment, salt and rust, but does not stop the leak itself. Repair and coating stop it.
Why is it hard to reach the entry holes on a large tank?
A large tank sits in the middle of the roof surrounded by walls and beams. Some holes are on the far side or under beams.
Do old wide pipes require full replacement?
If the leak is from one point, we repair it. If rust is distributed along the pipe, full pipe replacement may be needed.
How long does it take to empty and dry a large tank in Harat Al Sham?
Large tanks take a day or more to empty and fully dry, especially on limited roofs.
Does internal coating protect against new leaks under high pressure?
Good coating protects for many years. But if pressure is very high or the tank is very old, we may need regular checks.
How much does tank leak repair in Harat Al Sham 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 Harat Al Sham.
