Tank leak repair in Al Mahamid Jeddah
Al Mahamid is an unplanned quarter on the eastern edge of Jeddah beside the Old Makkah Road, with simple and old buildings. Tanks here suffer from leaks caused by saline groundwater and pipes buried beneath unpaved streets. Diagnosing a leak starts by closing the float valve and outlet and watching the level fall to know whether the loss is the tank itself or the plumbing.

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 Mahamid
Pipes and tanks here are very old and salt water plus groundwater moisture cause rapid corrosion in metals and concrete. The method is set out in full on Tank leak repair in detail.
Old tanks with deep rust
Most tanks in Al Mahamid are made of old cement or corroded galvanised iron. Rust penetrates the walls and under pressure water seeps from tiny holes in the base and sides.
Buried pipes beneath unpaved streets
Many streets remain unpaved with old pipes buried beneath them without adequate protection. Ground movement and moisture crack the pipes and cause leaks through foundations.
High groundwater and salinity
Al Mahamid lies on Jeddah's coastal edge where groundwater is saline and high. This accelerates corrosion on tanks and pipes and speeds crack growth and leaking.
Landmarks of Al Mahamid
Access to Al Mahamid runs via Harazat Road as the main entry. The district is bounded by the Old Makkah Road to the west and rural areas to the east.

Where the water leaves decides how it is repaired
A mixed residential quarter on Jeddah's eastern edge beside the Old Makkah Road, accessed mainly via Harazat Road. Many streets remain unpaved and drainage systems are old.
Damp and salt on the outside wall
Fine cracks in cement tank walls first appear around the base corners and sides where water and groundwater moisture collect.
The kind of crack
Rust holes in steel tanks start from the base and sides, especially at weld seams and corners.
The wall to floor junction
Inlet and outlet pipes crack from pressure and ground movement beneath unpaved streets.
Pipe entries
Saline groundwater rises with rain and evaporation, speeding corrosion on metals and concrete.
The condition of the old lining
Salt sediment and rust accumulate on the tank floor, clog openings and hide small cracks.
What the tank is made of
Old tanks not cleaned for years contain thick sediment layers that hide the real leaks.
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 Umm Al Salam Sub-Municipality
The Umm Al Salam sub municipality covers the east and south east of Jeddah along the Old Makkah Road and the Haramain Road. It pairs recently planned districts such as Al Wahah, Al Nakhil and Al Shuruq with popular districts that grew outside formal planning, including Al Harazat, Al Mahamid and Umm Al Salam. The older areas have ageing drainage, unpaved streets and vacant plots where building waste collects, conditions that suit rodents, cockroaches and ants. The newer areas are ringed by half built subdivisions and open excavations.
Questions about this district
How do we know if the leak is in the tank itself or the plumbing?
We close the ball and outlet valve and watch the level. If it falls the leak is in the tank; if it holds the problem is in the piping outside.
Are cement tanks in Al Mahamid corroding faster than steel ones?
Yes. Salt water and groundwater moisture penetrate cement faster and cause internal cracks. Steel rusts differently but leaks at pipe entry points.
Is lining the tank instead of repair enough?
No. Lining comes after cracks and holes are repaired. Lining over an unrepaired crack does not hold.
Why do tanks in Al Mahamid leak more than other areas?
Groundwater here is very saline and high, pipes lie under unpaved streets and ground movement breaks them constantly.
Is draining and cleaning the tank before repair necessary?
Yes. We drain water, sediment and rust and dry the interior before repair so the patch adheres properly.
How long does it take to repair a tank with a pipe entry leak?
Depends where the pipe leaks. If outside the tank we fix it quickly; if at the tank entry we drain and dry first.
How much does tank leak repair in Al Mahamid 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 Mahamid.
