Tank leak repair in Al Mahjar Jeddah
Al Mahjar is a mixed quarter combining large medical facilities with residential buildings and shops. Tanks here vary widely in size and age: old tanks in villas and apartment blocks, modern tanks in hospitals and medical centres. Leaks may come from cracks in concrete or from old pipe joints connected to complex medical systems.
-
Potable-rated materials
Linings and disinfectants cleared for drinking water tanks, not general-purpose products.
-
You get the downtime first
How many hours the tank is out of service, told before we start rather than after we finish.
-
A first-draw flush
We run the first draw off after refilling, and the tank is not handed back until the water runs clear.

Ground and roof tanks
Villas, apartment blocks and premises that need a written record of each visit.
Why the job is different in Al Mahjar
Tanks in Al Mahjar range from modern installations in hospitals to aging tanks in residential villas and apartment blocks. Salt-laden air and coastal moisture accelerate concrete and pipe corrosion throughout the district. The method is set out in full on Tank leak repair in detail.
Tanks in major medical facilities are complex and interconnected
King Abdulaziz Hospital and Ibn Sina College each house massive tanks linked to intricate distribution systems. A leak may be in the tank itself or in buried distribution pipes several metres below ground.
Old villas and apartment blocks have overhead tanks on weak foundations
Older residential properties have roof tanks or cylindrical tanks on structures. Cracks in aged concrete and corrosion in old pipe joints are the main sources. High water pressure widens existing fractures.
Coastal salt and moisture accelerate decay
Al Mahjar lies near the coast where salt and humidity attack concrete and metals rapidly. Tanks built decades ago fail faster here than in inland quarters.
Landmarks of Al Mahjar
Access to tanks in Al Mahjar runs via King Faisal Road, Al Mahjar Street and Zainal Street, with King Abdulaziz Hospital, the Mental Health Hospital and the Petromin station marking clear boundaries.

Where the water leaves decides how it is repaired
A mixed district south of Jeddah west of Al Wazeeriyah towards the coast. It occupies the old quarantine station site now home to King Abdulaziz Hospital. King Faisal Road, Al Mahjar Street and Zainal Street cross through it. The Jeddah Mental Health Hospital, Ibn Sina College Hospital and Petromin Souq stand within it, with the old popular Petromin quarter adjoining to the west.
Damp and salt on the outside wall
Leak detection begins by closing valves and watching level drop, which on its own tells us if loss is the tank or the plumbing.
The kind of crack
Concrete inspection focuses on fine and deep cracks in tank walls, which widen due to salt and coastal moisture in Al Mahjar.
The wall to floor junction
Pipe and joint inspection looks for corrosion in old metals and at the connection points where pipes enter the tank body.
Pipe entries
Foundation and structural inspection confirms no ground movement or subsidence causing new cracks in the tank.
The condition of the old lining
Internal lining inspection, if present, checks for cracking or separation from tank walls due to age or water pressure.
What the tank is made of
Pressure and load inspection measures system pressure, because high pressure widens existing cracks faster.
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 South Sub-Municipality
The South sub municipality runs from the edge of Old Makkah Road down to Al Khumrah and the southern corniche. Dense residential districts sit beside new subdivisions such as Al Sanabil and Al Taawun, warehouse fringes such as Al Saruriyah and Al Sarawat, and an old seaside settlement at Al Quzayn. Open stormwater channels cross the housing, and the warehouses, the vegetable and livestock markets and the nearby Islamic Port and Industrial City give pests shelter, food and year round humidity. Pressure is greatest in the older quarters, where drainage networks are ageing.
Questions about this district
How do we tell if the leak is in the tank or in the pipes?
We close the float valve and outlet, then watch the level drop. If it falls with valves shut, the leak is in the tank. If it holds steady, the leak is in connected piping.
Do medical facility pipes need different handling?
Yes. Pipes in hospitals connect to complex systems. We must isolate the tank from the entire system before repair to avoid disrupting hospital services.
Does coastal salt and humidity speed up leaks?
Yes. Salt eats concrete and metal. Tanks in Al Mahjar need more frequent maintenance than tanks in inland quarters.
Is tank lining enough to fix a leak?
No. Lining does not solve the problem if cracks exist. Cracks and joints must be repaired first, then lining applied after.
How do we handle deep underground tanks in hospitals?
Deep tanks need precise detection from above. We place sensors in inspection ports and monitor the drop rate to locate the leak before excavation.
Does an old tank need replacing or is repair enough?
If cracks are few and concrete is sound, repair works. If cracks are many and leaks recur, replacement is better, especially in Al Mahjar where salt corrodes concrete fast.
How much does tank leak repair in Al Mahjar 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 Mahjar.
