Water tank sealing in Al Faisaliyah Jeddah
Al Faisaliyah is a dense mixed residential quarter with older apartment blocks interspersed with mid-range villas, and Sari Street carries heavy commercial traffic from restaurants and banks daily. Water tanks in buildings here are old and need regular maintenance because foundations and roof surfaces undergo constant expansion and contraction from extreme heat and coastal humidity. Tank cracks and water seepage are recurring problems across the quarter.

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 Faisaliyah
Most buildings date from thirty years ago or earlier, and their tanks need regular repair because concrete cracks from heat, humidity and salt damage. The method is set out in full on what Water tank sealing involves.
Tanks on old roofs in congested apartment buildings
Roofs in Al Faisaliyah are tight and tanks sit exposed to direct sun and coastal humidity. Concrete cracks from daily and seasonal expansion, and seepage easily reaches apartments below.
Weak joints and pipe entries in old tanks
Floor-to-wall joints and pipe entries in old tanks are not sealed and need relining. Some tanks were built with outdated methods and cracking around pipes is common.
Tank pressure from heavy daily use
Al Faisaliyah has restaurants, banks and many residents, so tanks bear continuous water pressure throughout the day. Pressure and movement increase cracking and seepage downward.

Open in Google MapsWhat we read before any material is opened
A densely built residential quarter in northern Jeddah on King Fahd Road, bounded by Prince Majid Road and Madinah Road, with numerous apartment buildings, scattered villas and the commercial spine of Sari Street.
Cracking in the wall
Vertical cracks in tank walls from thermal expansion and constant water pressure.
The floor to wall joint
Horizontal cracks in the tank floor from hydrostatic pressure and uneven settlement.
The condition of the old lining
The floor-to-wall joint is a weak point and water seepage often starts there.
Sediment and scale
Pipe entries (inlet, outlet and vent) are not sealed and need new sealant around each.
The pipe entries
Concrete quality is old and salt from coastal humidity weakens it rapidly.
The hatch and the vent
Internal lining requires a clean surface free of algae and dirt before application.
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 Faisaliyah
Apartment district: residential blocks, repeated floors and shared entrances
Al Faisaliyah has dense apartment buildings and scattered villas, each with one or more tanks on the roof. Dense apartment complexes need large tanks under high pressure, while villas may have older tanks weakened differently by heat and humidity exposure.
Questions about this district
Why do tanks in Al Faisaliyah crack faster than in newer areas?
Tanks sit exposed to intense heat on open roofs and coastal humidity. Daily expansion and contraction weakens old concrete quickly.
Is lining alone enough or must cracks be repaired first?
Cracks must be repaired first. If we line over deep cracks, water seeps through from underneath.
What drives the cost of sealing a tank in this area?
Tank size, number of cracks and condition of pipe joints matter most. Old tanks with no prior maintenance need more work.
Can the tank be used during repair or must it be drained completely?
It must be drained completely and the interior surface cleaned. Lining needs a dry surface free of dirt and algae.
Do apartment buildings need different sealing than villas?
Yes. Dense apartment complexes have larger tanks and higher water pressure. Villas usually have smaller tanks but may be older.
How often should a tank be inspected after sealing?
Annual inspection is usually enough. If you spot any seepage, inspect immediately.
How much does water tank sealing in Al Faisaliyah 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 Faisaliyah.
