Tank leak repair in North Prince Fawaz Jeddah
North Prince Fawaz is an integrated residential extension in south Jeddah with apartment blocks and mid-sized villas distributed on a regular grid. Tanks here leak because joints and connections are weak, foundations are still settling and daily thermal expansion stresses seams. The foundations are relatively modern but have not fully stabilised.

Why the job is different in North Prince Fawaz
Buildings are recently constructed and foundations are still settling. Tank leaks appear as slow seepage from joints and pipes rather than deep cracks. The method is set out in full on how we approach Tank leak repair.
Weak joints and connections in modern tanks
Recently built tanks made from concrete or fibreglass have seams and connections that may not be fully watertight. Water slowly seeps from these joints and increases as the foundation shifts.
Inlet and outlet pipes separate from the wall
Water pipes are mounted on tank walls without full flexibility. When the building or tank moves, pipes separate slightly from the wall and begin leaking at the joint.
Daily thermal expansion worsens the problem
Roof-mounted tanks see direct sun all day and expand significantly. Modern seams slip under repeated expansion rather than crack.

Open in Google MapsWhere the water leaves decides how it is repaired
The northern half of the Prince Fawaz extension in south Jeddah, with apartment blocks and mid-sized villas on a regular layout. The district lies between Al Adl to the north and Al Fadl to the east, with Muhammad ibn Sahmi Street as the northern boundary.
Damp and salt on the outside wall
Seam leaks occur between tank sections in multi-part tanks because connections are new and not fully settled.
The kind of crack
Inlet pipe leaks occur at the wall joint because the pipe separates slightly when the building moves.
The wall to floor junction
Outlet leaks occur from the exit hole or discharge pipe due to poor installation or foundation movement.
Pipe entries
Moisture around tanks is moderate in the area, but daily thermal expansion from roof exposure or ambient heat worsens problems.
The condition of the old lining
Tanks in this area are relatively new and deep cracks are rare, but seams are weak and foundations are still settling.
What the tank is made of
Steady leaks from one point mean a pipe or seam, and valve closure monitoring identifies the source.
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 North Prince Fawaz
Mixed district: shops at street level with homes above them
A mixed area of recently built apartment blocks and villas on still-settling foundations. Treatment accounts for ongoing foundation movement, daily thermal expansion and weakness in new seams.
Questions about this district
Is leaking from new tanks normal in the first years?
It may be. New tanks may leak from seams and joints until foundations settle. Closing valves and monitoring tells us the leak source exactly.
Are inlet pipes the main cause of leaking here?
Partly yes. Inlet and outlet pipes separate from the wall due to movement or poor installation. This is more common than deep cracks in modern buildings.
Does reconnecting the pipes stop the leak for good?
It may stop it temporarily only. If foundation movement continues, pipes may separate again. Proper repair requires foundation stabilisation first, then tightening connections.
How long until foundations and tanks fully settle?
Usually one to two years after construction. During this time seepage may continue from joints and pipes.
Are roof tanks better than underground tanks for leaking?
Roof tanks face more thermal expansion from heat. Underground tanks are less exposed to heat but more prone to lateral water pressure.
Does sealing joints with caulk stop the current leak?
It may stop it temporarily, but caulk is not a permanent fix. Draining, cleaning and internal repair are necessary to prevent recurrence.
How much does tank leak repair in North Prince Fawaz 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 North Prince Fawaz.
