Tank leak repair in Al Andalus Jeddah
Al Andalus is an upmarket northern district along Andalus Road with spacious villas and modern apartment blocks. Tanks here are usually recently made but face very high water pressure from the main network and intense sun affects tank materials.
-
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 Al Andalus
Villas and buildings here are relatively modern, tanks are made of fibreglass and reinforced concrete with modern design, but high pressure and heat cause fine cracks to form rapidly. The method is set out in full on Tank leak repair in detail.
Fibreglass cracks from heat and pressure
Modern fibreglass tanks are light and efficient but the sun heats them intensely and high pressure strains them. Fine cracks appear quickly, especially at joints and corners.
Weak joints between fibreglass and metal pipes
Metal pipe connections to fibreglass tanks may not seal tightly. The difference in thermal expansion between the materials causes cracks in the seal rapidly.
High pressure from the Corniche network
The network here runs close to the main coastal pump station and pressure is very high. The pressure places constant strain on tank walls and joints.
The character of Al Andalus
Villa district: private plots, gardens and a boundary wall to every house
Al Andalus is a district of modern upmarket villas and apartment buildings, and tanks here use the latest technology but face very high pressure and intense sun. Repair must account for modern materials, high pressure and a harsh coastal environment.
Where the water leaves decides how it is repaired
A central northern district along Andalus Road close to the Corniche, with upmarket apartment buildings and spacious villas alongside commercial frontages on Tahliah. It lies north of Prince Mohammed bin Abdulaziz Street, the shoreline is nearby and King Fahd General Hospital marks its western edge.
Damp and salt on the outside wall
The float valve in fibreglass tanks fails quickly from high pressure and causes the tank to overflow.
The kind of crack
Copper pipe joints and flanges corrode from salt and moisture from the sea and continuous pressure.
The wall to floor junction
Fibreglass tank walls crack from daily thermal expansion and continuous internal pressure.
Pipe entries
High humidity and salt from the Corniche and sea accelerate corrosion of metals and seals.
The condition of the old lining
Tank floor may corrode from salt, mineral sediment and stagnant water inside.
What the tank is made of
Joints and corners in the tank are the first places to crack because of uneven pressure and heat.
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 Aziziyah Sub-Municipality
The Al Aziziyah sub municipality takes in the established heart of northern Jeddah, from the Al Hamra corniche on the Red Sea to Al Rehab east of King Abdullah Road. Its buildings date back decades, mostly mid rise apartment blocks over shops and closely packed restaurants along Makarona Road, Tahliah Street and Palestine Street, alongside villas and hotel towers near the shore. Sea humidity is high in the western districts, plumbing and drainage in the older blocks are ageing, and food outlets, hospitals and irrigated gardens are everywhere, conditions that favour cockroaches, ants, mosquitoes and rodents throughout the year.
Questions about this district
Is a new fibreglass tank exposed to leaks even though it is recent?
Yes. Fibreglass is affected by heat and high pressure quickly. Joints especially are weak and cracks appear within a few years.
Why does the tank leak at the joint between the body and the floor?
This joint bears very high pressure. The seal dries and shrinks with heat and humidity, and water seeps from there.
Is sealing a crack with external adhesive enough?
No. Internal pressure pushes water outward. The tank must be drained and the crack repaired from inside with strong material and a new seal.
How do we handle the joint between copper pipes and fibreglass?
Copper and fibreglass expand at different rates. We use a flexible intermediate and clean the old seal completely before fitting a new one.
Do villa tanks differ from apartment building tanks?
Slightly. Villas usually have smaller fibreglass tanks and buildings have reinforced concrete. Both leak for somewhat different reasons but testing and repair are similar.
How often should the tank be cleaned in a district close to the Corniche?
At least once a year. Salt and humidity from the sea enter the tank through cracks and sediment builds up faster.
How much does tank leak repair in Al Andalus 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 Andalus.
