Tank leak repair in Ghulail Jeddah

Ghulail is a decades-old popular quarter in south Jeddah next to the former Al Mahjar quarantine district. The entire area has been cleared under the South Jeddah redevelopment programme and land now awaits rebuilding. New tanks and pipework in projects under construction need careful inspection before and during installation to prevent early leaks.

  • Potable-rated materials

    Linings and disinfectants cleared for drinking water tanks, not general-purpose products.

  • You get the downtime first

    How many hours the tank is out of service, told before we start rather than after we finish.

  • A first-draw flush

    We run the first draw off after refilling, and the tank is not handed back until the water runs clear.

  • Ground and roof tanks

    Villas, apartment blocks and premises that need a written record of each visit.

Why the job is different in Ghulail

Cleared land retains high moisture from the old drainage system, and new projects under construction use modern tanks but are at risk of leaks during installation and initial pressure testing. The method is set out in full on Tank leak repair in detail.

The first reason

Tanks in new construction projects

New buildings in Ghulail are still under construction and underground and overhead tanks are newly installed. Leak inspection must happen before the first fill to prevent water loss and catch factory defects early.

The second reason

Supply and outlet piping in a new system

Modern pipes in new projects are installed in fresh concrete walls and floors. Leaks often occur at connection points and where pipes enter the tank itself because seals have not yet cured.

The third reason

Wet foundations from the old drainage network

Cleared land retains moisture from the old drainage and waste system. New underground tanks sit on damp soil, and moisture may press on tank walls and cause internal leaks.

The character of Ghulail

New development: ongoing construction and vacant plots between the homes

Ghulail is now a new-development zone and buildings under construction require different treatment. Tanks are modern but prone to factory and installation defects, and damp soil underneath increases wall pressure. Repair must be thorough and sealed because buildings are new and owners expect leak-free tanks.

Before treatment

Where the water leaves decides how it is repaired

A historic popular quarter in south Jeddah whose narrow lanes and worn streets suffered from failed drainage and uncollected refuse. The old buildings have been demolished entirely and the land is now in the early phase of comprehensive redevelopment.

A concrete wall marked with damp and a white salt bloom

Damp and salt on the outside wall

Modern underground tanks in new projects may leak from hairline cracks in concrete walls if the pour was not done correctly.

A fine crack running across a concrete surface

The kind of crack

Supply pipes enter the tank from above or the side, and the entry point and metal ring around it are a very common leak source.

The corner where a concrete floor meets a wall

The wall to floor junction

Outlet valve leaks occur because plastic seals have not yet cured or are defective from the factory.

Water pipes passing through a concrete wall

Pipe entries

High soil moisture presses on tank walls from outside, which may cause internal leaks through small cracks.

The condition of the old lining

Cracks appear in underground tanks at weak points in the concrete, often at corners or around pipe holes.

How we work

  1. 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. 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. 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. 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 technician inspecting with a flashlight

    A marked level test

    A reading before and after with everything shut, which establishes that the loss is the tank and not the plumbing.

  • A metal floor drain

    Draining and sediment removal

    Water and silt out of the base, so the floor and the walls can be seen as they really are.

  • A spray nozzle in close detail

    Pressure wash and dry back

    The weak layer and the dust come off, because a repair only holds on sound concrete.

  • A gloved hand applying bait into a joint

    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.

  • The visit report being written on a clipboard

    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.

  • A clean kitchen counter after treatment

    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 Jamiah Sub-Municipality

Al Jamiah sub municipality spans the older south of Jeddah. Planned districts such as Al Fayha, Al Thaghr and Madain Al Fahd sit beside crowded popular quarters like the Nazlahs and Al Quraiyat, and beside cleared or clearing land in Ghulail, Petromin and Al Thaalibah awaiting redevelopment. Apartment buildings stand close together above dense runs of shops and restaurants along Old Makkah Road and Prince Majid Road. Drainage in the popular quarters is ageing, humid air drifts in from the port and refinery side to the west, and the flat low lying ground holds rainwater in narrow streets.

Questions about this district

Are new tanks in Ghulail prone to early leaks?

They can be during initial pressure testing due to factory defects or incomplete sealing. Pre-use inspection catches the problem early.

How do we distinguish between a tank leak and a pipe leak in a new project?

We close the float and outlet valves and watch the level fall. Slow fall means the tank itself leaks. No fall means pipes outside it are the problem.

Does high soil moisture affect new underground tanks?

Yes. Moisture presses from outside and may cause leaks through small cracks or weak points in the walls.

Can we repair a tank without draining it completely?

No. The tank must be drained, cleaned and dried fully before repair so we can see the crack and fix it properly.

What is the difference between crack repair and internal lining?

Repair means sealing the crack with real material. Lining comes after repair to protect it, never instead of it.

Is the pipe entry point a common leak source?

Yes, very common. The pipe entry point, seal and metal ring around the pipe are frequent leak sources in new tanks.

How much does tank leak repair in Ghulail 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 Ghulail.
