Tank leak repair in Al Rawabi Makkah
Al Rawabi is a hillside district with high-density towers built to house Umrah pilgrims. Tanks sit on the roofs of these buildings and face high water pressure from the steep topography and elevation gain. Leaks here usually occur at the inlet and outlet pipes because pressure, heat and frequent supply cuts strain the joints.

Why the job is different in Al Rawabi
Buildings here are very tall and tanks sit on very high roofs, creating a very large elevation head from intake to outlet. The method is set out in full on our Tank leak repair service.
Strong water pressure on inlet and outlet pipes
A tank on a high roof means intense pressure on water entry and exit pipes. Fittings and elbows face constant mechanical strain, and leaks begin at the joint where pipe meets tank body.
Steep topography and hillside slope affect tank balance
The district sits on very steep slopes with buildings set on deep rock foundations. Ground movement and minor subsidence cause tank body flex and wall cracking.
Intense heat on very high roofs
Tanks on high roofs face direct sun exposure all day and the material expands and contracts daily. This weakens welds and opens fine cracks in the walls.
The character of Al Rawabi
Apartment district: residential blocks, repeated floors and shared entrances
A district of very high-rise apartments means tanks sit on very high roofs under strong pressure. Repair focuses on testing pressure first, then isolating whether the leak is in pipes or tank body, because high pressure may hide slow leaks or accelerate them.
Where the water leaves decides how it is repaired
A steep hillside district south of the Grand Mosque, built on slopes cut through by tunnels linking east and west, with Al Rawabi Garden and the Jabal Khandamah viewpoint sitting above the high-rise blocks.
Damp and salt on the outside wall
Tank body cracks appear mostly on side walls facing the high pressure point and worsen with intense heat on the high roof.
The kind of crack
Inlet pipe leaks start at fittings and elbows because street pressure creates high stress on connections.
The wall to floor junction
Outlet pipe leaks occur where the water leaves the tank because the large elevation head creates variable pressure at the joint.
Pipe entries
Moisture around the tank base and pipes appears because daily heat and night cooling cause condensation and slow seeping.
The condition of the old lining
Rust and sediment build up fast inside the tank because incoming water carries salts and particles from the main line.
What the tank is made of
Level drop at night with no usage means real leakage from tank or pipes, not evaporation.
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 Al Misfalah Sub-Municipality
Al Misfalah sub municipality runs downhill from the south of the Grand Mosque through Al Misfalah, Kudai and Al Rawabi to Al Taqwa, Al Hindawiyah, Al Khalidiyah and Al Rusayfah at the third ring road. The northern end is old apartment blocks and pilgrim hotels with restaurants along Ibrahim Al Khalil Street and the huge coach parks at Kudai. The south and west are dense popular districts with countless small shops and unplanned hillside housing, some of it already cleared for redevelopment, giving way to orderly land grant schemes in Al Rusayfah beside the railway station.
Questions about this district
Does the leak always come from the tank body or from the pipes?
In Al Rawabi most leaks originate from inlet and outlet pipes because high pressure strains the joints. But older tanks may crack internally from daily expansion and contraction.
Why does the tank leak again a month after the last repair?
If the tank was not drained and cleaned before repair, rust and sediment deposit weaken the patch. High pressure may then open a leak at another point.
Does the colour of leaking water tell us exactly where it comes from?
Yes. Clear water means the leak is from clean pipes. Brown or black water means the leak is from inside the old tank.
How many times do we test the tank before declaring it fixed?
We close the float and outlet valves and watch the level. Slow fall means light leakage from pipes. Rapid fall means the leak is in the tank itself.
Does internal coating solve the leak problem?
Coating protects from rust but does not seal cracks. The crack itself must be repaired first by draining, drying and filling, then coating follows.
Do very high rooftop tanks need different repair methods?
Yes. High pressure means we focus on inlet and outlet pipes first and test all fittings. The tank itself may need additional bracing or rebalancing.
How much does tank leak repair in Al Rawabi 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 Rawabi.
