Water tank sealing in Al Aziziyah Jeddah
Al Aziziyah is a dense mixed district with apartment blocks over shops and villas in numbered sections, serving busy markets and popular restaurants. Tanks here face constant pressure from heavy daily use and extreme heat, and cracks and leaks start early in closely packed buildings.
-
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 Aziziyah
Tanks in Al Aziziyah suffer early cracks and leaks because extreme heat and heavy use place stress on aging linings before their time. The method is set out in full on the full Water tank sealing page.
Apartment blocks with retail below
Mixed-use buildings along Makarona Road mean tanks sit on high roofs in very hot zones. Linings crack from rapid thermal expansion and contraction.
Detached villas in numbered sections
Villas have smaller tanks in confined spaces, and leaks quickly reach foundations. Access to the tank opening may be restricted.
Busy markets need clean water without interruption
Commercial shops, restaurants and cafes consume large volumes daily. Any leak means direct loss and rapid water contamination before the next refill.
Al Aziziyah on the map
Al Aziziyah sits about 1.5 km from Mushrifah and about 3 km from Al Rehab.
Open in Google MapsWhat we read before any material is opened
A densely built mixed-character quarter north east of central Jeddah, bounded by Tahliah Street to the north, Gharnatah Street to the south, Al Arbaeen Street to the east and Al Sitteen Street to the west, with residential blocks over ground-floor shops and detached villas.
Cracking in the wall
Visual inspection finds hairline cracks and flaking in zones exposed to direct heat on the roof surface.
The floor to wall joint
The wall-to-floor joint is the first weak point in heavily used tanks, and water begins leaking from here.
The condition of the old lining
Pipe entries and inlet/outlet holes need close inspection because the lining may have worn around metal edges.
Sediment and scale
Soil moisture beneath the tank means leaks will show quickly on the exterior or foundation face.
The pipe entries
Deterioration may be in deep cracks or in gaps between the old lining and concrete walls.
The hatch and the vent
Bacterial and algal activity shows in leaking tanks because water stays hot and partly stagnant.
How we work
-
1
Inspect with the tank empty
We drain it and read the surface dry: whether the water leaves through a crack, a joint or a pipe collar, and what the outer face of the wall and the ceiling below are telling us. A level test with the valves closed separates a leaking tank from leaking pipework.
-
2
Clean and prepare the substrate
Sediment out, a high pressure wash, the loose old lining and the weak surface layer of the concrete taken back, then dried. The material grips sound substrate and nothing else.
-
3
Make the cracks and joints good
Cracks are chased out and filled with a repair mortar, a cove is formed where the floor meets the wall, and every pipe collar is treated on its own.
-
4
Lining, fill test, sterilisation
Successive coats, each run across the one beneath it, on the face the water touches. Then a full cure, a fill with the level watched, and sterilisation with the first fill run to waste before the tank returns to use.
What water tank sealing includes
-
Finding where the water leaves
Carried out drained and dry: cracks, joints, pipe collars and the outer face of the wall.
-
Draining and sediment removal
The last of the water and the settled layer on the floor come out, because a lining does not stick over sediment.
-
Cracks and joints made good
The crack opened and filled, a cove formed at the floor to wall junction, and each pipe entry worked separately.
-
Lining coats on the water face
More than one coat, each crossing the one below, in material made for drinking water tanks rather than roof waterproofing.
-
Curing, fill test and sterilisation
The material is left to cure, the tank is filled and the level watched, then sterilised and the first fill run to waste. How long the cure takes follows the material and the weather, and we tell you before the date so you can plan around the supply.
-
A follow-up level check
We come back once it is in service to read the level and check the outer face, because any remaining loss shows up then rather than on the day of the work.
The character of Al Aziziyah
Mixed district: shops at street level with homes above them
A mixed district with both apartment blocks and detached villas means tanks of different sizes and access patterns. Treatment must adapt to large residential tanks and smaller commercial ones.
Questions about this district
Why do tanks in Al Aziziyah crack faster than in newer areas?
Extreme heat and heavy daily use cause constant expansion and contraction of the lining. Old linings cannot withstand this thermal stress.
Do most leaks start from the walls or the floor?
In Al Aziziyah, most leaks begin at the wall-to-floor joint because thermal movement opens this seam. Partial cracks in the walls follow later.
Is filling the tank with water enough to spot a leak?
No, small leaks may not show for days. Visual inspection of the lining and joints is necessary.
Does fixing a small leak stop damage spreading?
If caught early yes, but if small cracks are left to grow, a full lining renewal may become needed.
How does heavy use speed deterioration?
Tanks in frequent use (shops, cafes) degrade faster. Continuous running water increases pressure on the lining.
Do salt and heavy minerals speed corrosion?
Yes, salts deposit on the lining and create weak spots. Water quality directly affects lining life.
How much does water tank sealing in Al Aziziyah 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 Aziziyah.
