Tank leak repair in Al Qararah Al Jadid Makkah
Al Qararah Al Jadid is an entirely new district in the Crown Prince development schemes, with residential and commercial buildings and large cisterns buried beneath floor slabs. The ground is flat and construction is new, but the cisterns face high groundwater and strong ground pressure. Leaks here may stem from differential settlement in new foundations or from groundwater pressing on the tank from outside.

Why the job is different in Al Qararah Al Jadid
Most cisterns in Al Qararah Al Jadid are buried beneath slabs because of modern design, and groundwater is very high in this southern sector of Jeddah. The method is set out in full on Tank leak repair in detail.
High groundwater and external pressure on cisterns
South Jeddah has very shallow groundwater. Groundwater presses on the external walls of underground cisterns, and new concrete may not be tight enough to withstand continuous pressure.
Differential settlement and new cracks
The terrain in Al Qararah is flat but layered with soils of differing density. New foundations settle at different rates, and the buried cistern may drop faster than the building, opening cracks.
New concrete and early slow seepage
Cisterns in active construction projects are often freshly poured. Young concrete has not matured and may contain fine voids, and slow seepage can begin in the first few weeks.
Landmarks of Al Qararah Al Jadid
Access to Al Qararah Al Jadid projects runs via the southern extension of Ibrahim Al Khalil Road, with Wadi Uranah cutting across flat open ground and Jabal Labanah standing to the north as natural landmarks defining the zone.

Where the water leaves decides how it is repaired
A new development zone within Crown Prince projects, south of Al Mudaa Al Jadid along the southern extension of Ibrahim Al Khalil Road. The terrain is flat, construction is recent and buildings are actively rising.
Damp and salt on the outside wall
Fine cracks in walls of freshly poured underground cisterns from incomplete mixing or small air voids in the concrete matrix.
The kind of crack
Groundwater seepage and continuous external pressure on cistern walls from surrounding water acting as a constant driving force.
The wall to floor junction
Cracks from differential settlement between the cistern and the building, where the cistern sinks faster than the foundation above.
Pipe entries
Very high humidity and shallow groundwater in the southern Al Qararah zone increase pressure and moisture around the cistern.
The condition of the old lining
Underground cisterns are buried deep beneath slabs and ground pressure and groundwater press with force on all walls and the floor of the cistern.
What the tank is made of
Slow and ongoing seepage from chronic pressure may stop during dry spells but returns with any rise in the groundwater table.
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 Makkah Sub-Municipality
South Makkah sub municipality is the belt of Crown Prince schemes south of Al Ukayshiyah, along the Al Laith road and the extension of Ibrahim Al Khalil Road to the Fifth Ring Road and the Non Muslims bypass. Most of it is still bare: granted plots awaiting houses, new villas standing alone, open building sites and unfinished paving and drainage. Wadi Uranah and its tributaries cross the low ground and hold water after rain, hills close it in, and rodents, reptiles and scorpions shelter in stacked materials and foundation pits before the neighbourhoods fill up.
Questions about this district
Is high groundwater the main cause of leaks in Al Qararah Al Jadid?
Often yes. Groundwater presses on the cistern from outside and new concrete may not yet be tight, resulting in slow seepage.
Is leaking normal in new cisterns or a sign of defect?
Slow seepage in the first weeks may come from young concrete not yet set. If it continues or worsens, it signals a defect in pouring or mix design.
Can we repair an underground cistern without tearing up the floor?
If the leak is very small and coming from the outside, we may repair it internally. If it is from an internal crack or hole, we may need to open part of the slab.
Why is differential settlement dangerous for underground cisterns?
Uneven settlement creates cracks in concrete. A cistern that drops faster than the building above it bears stress and fractures.
Does internal treatment of the cistern stop pressure from external groundwater?
Internal repair stops the leak but external pressure remains. If pressure rises, we may recommend external waterproofing from outside.
What is the best time to repair a leak in a new cistern?
As soon as possible. Early leaks in young concrete are easier to fix, and delays allow cracks to widen.
How much does tank leak repair in Al Qararah Al Jadid 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 Qararah Al Jadid.
