Tank leak repair in Al Hajun Makkah
Al Hajun is a historic quarter on slopes around the Grand Mosque and Al Mualla cemetery. Buildings are very old and perch on steep hillsides; tanks were placed without modern standards. High groundwater and pressure from steep elevation cause constant leaks in old foundations and tanks.

Ground and roof tanks
Villas, apartment blocks and premises that need a written record of each visit.
Why the job is different in Al Hajun
Buildings are very old and foundations are weakened by moisture, salt and ground movement. Groundwater lies close to the surface because of proximity to Al Mualla cemetery. The method is set out in full on Tank leak repair in detail.
Old buildings on steep hillsides
Houses and apartment blocks were built on steep slopes with foundations dug into weak rock. Tanks were placed haphazardly on roofs or between floors.
High groundwater and constant moisture
The quarter lies near Al Mualla cemetery and groundwater rises very close to the surface. Moisture and salt penetrate buried tank foundations.
Severe pressure from elevation change
The quarter sits on sharp hillsides and pipe pressure from elevation difference is very high. Upper tanks create continuous pressure on pipes below.
The character of Al Hajun
Historic district: close-set buildings, narrow lanes and ageing services
A historic quarter on steep hillsides means very old, weak foundations. Tanks were installed without modern standards and groundwater lies very close. Repair must account for ancient foundations, extreme pressure, drainage and groundwater together.
Where the water leaves decides how it is repaired
A historic quarter north west of the Grand Mosque around Al Mualla cemetery on the slope of Jabal Al Hajun. Old buildings cling to hillsides, Hajun Street descends from the Hajun pass towards the Haram, the Second Ring Road and Ain Zubaidah Street cross the district, and Al Utaybiyah adjoins it northward.
Damp and salt on the outside wall
Cracks in tank walls from high pressure of groundwater pushing inward through weak old concrete.
The kind of crack
Leaks at internal and external pipe entries because extreme pressure and ground movement shift connections.
The wall to floor junction
Uneven pressure from steep elevation change creates continuous stress on the tank.
Pipe entries
Moisture and salt from groundwater penetrate old foundations and buried tanks quickly.
The condition of the old lining
Buried tanks in old foundations may shift from ground movement and minor slope slips.
What the tank is made of
Relief valve and shut-offs leak continuously from high variable pressure through the day.
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 Utaybiyah Sub-Municipality
Al Utaybiyah sub municipality covers the old districts north of the Grand Mosque: the hillside quarters of Al Hajun, Al Utaybiyah and Al Bayban, Al Zahir and Al Shuhada at the northern entrance, and the newer Al Zahra, Al Diyafah and An Nuzhah westward. Its building stock is among the oldest in Makkah, stone houses on the hills, packed apartment blocks and sewers decades old, threaded with crowded markets like the Utaybiyah souq and furnished flats that fill in the pilgrim seasons. Wadi Al Zahir and Wadi Al Tanim carry storm water through it, and industrial workshops line Hajj Street.
Questions about this district
Is tank leaking here caused by high groundwater?
Yes. Groundwater lies close to buried tanks. Outward pressure pushes water inward through small cracks.
Why are tanks in Al Hajun older and weaker than other quarters?
The quarter is very old and tanks were installed decades ago without modern standards. Moisture and salt weakened the walls.
Is fixing a crack enough or must groundwater around the tank be drained?
Crack repair is necessary but may not be enough. If external pressure is very high, draining water around the tank may be needed.
How do we repair a very old tank with weak walls?
If walls are very weak, we repair cracks and line. If damage is severe, replacement is safer than repair.
Do pipes on hillsides shift more than in flat areas?
Yes. Ground movement and minor slips on slopes gradually shift pipes. Regular inspection is essential.
What is the risk of leaving tank leaks unrepaired for long?
Leaks weaken foundations around the tank. Soil subsidence, wall cracks and foundation damage may threaten the building.
How much does tank leak repair in Al Hajun 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 Hajun.
