Tank leak repair in Harat Al Baharah Jeddah

Harat Al Baharah is an old quarter of Thuwal on the Red Sea coast, sitting directly beside Thuwal's historic harbour. Homes here are very close to the sea and salt and moisture affect all building materials. Tanks here face intense salt and sea spray that causes rapid corrosion and constant 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 Harat Al Baharah

Buildings here are very old and tanks are traditional concrete cisterns, mostly elevated or buried close to ground level. The method is set out in full on Tank leak repair in detail.

The first reason

Extreme proximity to sea and salt spray

Harat Al Baharah sits directly on the Red Sea coast with air saturated by sea salt. Tanks, pipes and all metal corrode at exceptionally fast rates and cracks appear far more quickly than in inland areas.

The second reason

Old traditional concrete tanks

Most homes have very old concrete cisterns dating back decades. Concrete walls have been eaten away by salt, moisture and repeated daily temperature cycles.

The third reason

Pipes exposed to harsh marine corrosion

Pipes run across roofs very close to the sea and salt deposits on them constantly. Copper and iron rust rapidly and flanges need frequent replacement.

The character of Harat Al Baharah

Mixed district: shops at street level with homes above them

An old quarter directly on the sea means all tanks and pipes suffer constant salt corrosion. Treatment focuses on salt and moisture resistant materials and may require frequent replacements rather than simple spot repairs.

Before treatment

Where the water leaves decides how it is repaired

An old quarter of the fishing town Thuwal, with homes close to Thuwal's historic harbour and the corniche maintained by Saudi Aramco along the shore.

Damp and salt on the outside wall

Float valve and outlet valve inspection determines the leak source while checking flanges for salt corrosion damage.

The kind of crack

Concrete tank body inspection searches for fine cracks that may be hidden under salt and sediment layers.

External pipe inspection focuses on flanges and joints corroded by salt and sea wind exposure.

Water pipes passing through a concrete wall

Pipe entries

Inspection of salt deposits around the tank and pipes reveals leak points and ongoing corrosion activity.

The condition of the old lining

Inspection of metals and pipe coatings confirms protective barriers against salt corrosion remain intact.

What the tank is made of

Complete inspection of foundations around buried tanks ensures water is not leaking into soil in the damp coastal environment.

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 Thuwal Sub-Municipality

Thuwal sub municipality is a small fishing town on the Red Sea coast at the far northern edge of Jeddah governorate. Its old quarters are closely packed popular and mud built houses on narrow streets, with newer low rise concrete homes from the town's development programme beside them. Sea humidity stays high all year, the fishing harbour and the corniche form its seafront, water arrives by tanker so household tanks are everywhere, and the town sits on Wadi Thuwal, ringed by open ground and by the irrigated green campus of King Abdullah University of Science and Technology.

Questions about this district

Why are leaks more common in Al Baharah than other Thuwal quarters?

Direct coastal location exposes tanks and pipes to sea salt continuously. Salt causes accelerated corrosion and cracks appear far more quickly.

Are copper pipes better than iron in a coastal environment?

Both corrode in coastal air, but copper may last slightly longer. Plastic pipes may be best but cost is higher.

Will patching a leak solve it in Al Baharah or will it return?

Patching is temporary only. We must drain, clean and properly repair cracks because salt deposits will cause new leaks.

How long do pipes last in Al Baharah before replacement?

Iron pipes may last only 5-7 years, copper longer. Annual inspection is absolutely necessary.

Is cleaning the tank of salt deposits enough or is deeper repair needed?

Cleaning is a necessary first step. But after that we need full crack inspection and repair before any final coating or lining.

Does proximity to the sea change the repair method?

Yes. We use salt and moisture resistant materials and may need complete pipe replacement instead of spot repairs.

How much does tank leak repair in Harat Al Baharah 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 Harat Al Baharah.
