Tank leak repair in Petromin Jeddah
Petromin is a new popular residential quarter in south Jeddah beside the Jeddah oil refinery. Buildings were built recently as part of a low-income housing scheme. Tanks are relatively new but built from materials vulnerable to salt and moisture from the port and refinery. We track the water path from tank inlet to outlet to determine whether leakage is from the concrete tank itself or from pipes and joints.

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 Petromin
Buildings and tanks are relatively new, built ten to fifteen years ago, but the salty marine environment near the port and refinery speeds corrosion. The method is set out in full on Tank leak repair in detail.
New tanks in harsh salt environment
Concrete tanks were built recently but salt from the port and refinery penetrates pores. Excess moisture from salt dust causes rapid cracking.
Modern pipes but under harsh conditions
Water pipework from tanks is new but exposed to salt and moisture. Pipe joints weaken quickly from electrical corrosion and salt attack.
Water demand rises in summer and refinery affects air quality
Many residents and extreme heat increase water demand. The nearby refinery may affect water quality and accelerate corrosion.
The character of Petromin
New development: ongoing construction and vacant plots between the homes
A new low-income residential quarter means relatively new tanks but a very harsh salt environment. Buildings are close together and space between tanks and rooftops is tight, so work needs specialist salt-resistant and moisture-resistant lining and careful protection of new structures.
Where the water leaves decides how it is repaired
A new popular residential quarter in south Jeddah beside Jeddah oil refinery, part of the old quarantine area known as Al Karantina. Low-income housing built close to a main road facing the refinery fence, within the city's redevelopment and planning programme.
Damp and salt on the outside wall
Finding fine cracks in new tanks requires careful inspection because hairline cracks may leak slowly.
The kind of crack
Checking joints between pipes and tank reveals whether seals are still intact or salt has begun to penetrate.
The wall to floor junction
Airborne seawater salt deposits on exposed tanks and causes continuous surface corrosion.
Pipe entries
Continuous leakage causes water loss and may introduce salt into remaining water.
The condition of the old lining
New tanks may contain water treatment or preservation materials that react with salt and moisture.
What the tank is made of
Pump pressure increases in each summer period and may trigger new leaks from existing fine cracks.
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 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
Why do tank leaks here occur faster than in other areas?
Salt and moisture from port and refinery penetrate concrete faster. The modern tank may not be designed for such harsh salt conditions.
Does a new tank leaking mean a construction defect?
It might. But salt and moisture can cause cracks even in properly built tanks if the environment is extremely harsh.
Is salt-resistant lining necessary here?
Yes. Standard lining does not protect against seawater salt. We need specialist lining resistant to salt and moisture.
How do we tell whether the tank leaks or the pipes?
We close the float valve and outlet and watch the level. If it drops and water pools beneath the tank, the tank leaks. If it does not drop, the leak is beyond the tank.
Is tank replacement better than repair in salt conditions?
If the leak is small, specialist repair and lining may suffice. If leakage is large or the tank is very weak, replacement may be better.
Does refinery water quality affect tank corrosion?
It may. Water containing chemicals or extra salt may accelerate internal corrosion.
How much does tank leak repair in Petromin 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 Petromin.
