Tank leak repair in Al Sabil Jeddah
Al Sabil holds a mix of old houses and modern apartment blocks squeezed between narrow lanes. Tanks sit exposed on flat roofs and undergo daily thermal stress. Leaks are common in older tanks and connected pipework. Detection starts by closing the float valve and measuring the rate of level fall to pinpoint the leak source.

Why the job is different in Al Sabil
Old houses in Al Sabil have tanks mounted directly on exposed flat roofs and old piping runs through damp walls of brick and stone. The method is set out in full on what Tank leak repair involves.
Tanks on exposed flat roofs
Most tanks in Al Sabil sit uninsulated on flat roofs exposed to full sun. Daily thermal swings cause cracks at wall junctions and pipe entry points, especially where metal meets old stone.
Pipe entry and exit through old damp walls
Inlet and outlet pipes pierce damp brick and stone walls. The thermal expansion coefficients of metal and stone differ, and when stone contracts small voids open around the entry point causing weeping.
Seasonal humidity swings and moisture absorption
In high-humidity seasons groundwater rises and old walls absorb extra moisture. Small cracks widen and leaking becomes visible. Outdoor piping expands and contracts between night and day cycles.
Al Sabil on the map
Al Sabil sits about 0.5 km from Al Sahifah and about 1.5 km from Al Ammariyah.

An old intermediate quarter lying between King Fahd Road and Old Makkah Road, bounded by King Khalid Street on its south and east and Al Makhzoumi Street on the west. Tightly packed older houses sit alongside modern apartment buildings.
Damp and salt on the outside wall
Level monitoring when valves are closed must be precise because most houses here lack standard water gauges.
The kind of crack
Tank cleaning removes sediment and mineral buildup from years of use, and sediment is heavy here due to older water quality.
The wall to floor junction
Inspection of pipe entries and valve flanges focuses on hairline cracks around metal and old stone junctions.
Pipe entries
Complete dryness before repair is essential, and humid air in Al Sabil slows the drying process.
The condition of the old lining
Crack repair uses flexible material that tolerates thermal cycling, not rigid cement which re-cracks.
What the tank is made of
Tank lining after repair provides long-term protection and modern materials handle slight salinity and moisture.
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.
The character of Al Sabil
Apartment district: residential blocks, repeated floors and shared entrances
Al Sabil is a dense residential area with a mix of old houses and modern buildings, meaning old tanks sit beside new piping. Repair must account for this mixed structure and handle complex piping runs and cracks in damp old masonry walls.
Questions about this district
How do we know the leak is from the tank body and not the pipes?
We close the float valve and the outlet and watch the level fall. If it drops with both closed, the leak is in the tank. If it holds, the leak is in the piping or valves.
Why does leaking worsen in summer more than winter?
Daily heat causes rapid expansion of the tank metal and existing cracks widen. Winter expansion is less and the leak may not show.
Does re-lining the tank stop a leak at the pipe entry point?
Lining covers the interior crack but does not solve the root cause. The entry point must be repaired first, then lining is applied after.
Can we repair the pipe entry without draining the tank?
No. The entry point needs complete dryness and cleaning before repair, and the tank must be empty and fully dry.
What is the difference between crack repair and lining?
Repair means sealing the crack inside and out and finding the root cause. Lining covers the interior only and does not stop exterior seepage or entry-point leaks.
How often per year does a tank in Al Sabil need cleaning and inspection?
At least once yearly, but in high-humidity areas with recurring leaks, twice yearly catches small cracks early.
How much does tank leak repair in Al Sabil 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 Sabil.
