Water tank sealing in Al Shira Jeddah
Al Shira is a relatively modern district on the northern corniche with contemporary villas, diverse apartment blocks and the King Abdullah Medical Complex nearby. Tanks here face constant exposure to sea salt, spray and high humidity. Sealing and repair must withstand a harsh marine environment.
-
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 Shira
Residents and hospital staff observe tank deterioration occurring faster than in inland quarters due to sea salt and year-round high humidity. The method is set out in full on our Water tank sealing service.
Marine environment accelerates corrosion
Tanks near the coast face salt spray and moisture in the air. Cement and metal degrade faster here than in interior districts and require stronger protective coatings.
New villas and buildings need sealing before service
Modern apartment blocks and villas have relatively new tanks but many were not properly sealed during initial construction. Weak initial sealing leads to early leakage and decay.
King Abdullah Complex drives continuous maintenance demand
The large hospital consumes vast water volumes and runs tanks at high capacity. Continuous sealing and maintenance is essential to prevent service interruption.
Landmarks of Al Shira
Access through Al Shira runs via Prince Abdulmajeed Road cutting across from the west, with King Abdullah Medical Complex as the central landmark and Prince Nayef Street and Aabir Al Qarat Street marking the service boundary.

What we read before any material is opened
A mixed-character coastal district bounded by North Obhur, Al Amwaj, Al Yaqut and Al Firdaws, lying along Prince Abdulmajeed Road, Prince Nayef Street and Aabir Al Qarat Street.
Cracking in the wall
Salt deposits coat walls, floor and joints, especially in corners and cavities where salt accumulates.
The floor to wall joint
Fine cracks start at the floor-to-wall joint and widen due to the chemical reaction between salt, moisture and cement.
The condition of the old lining
Pipe entries and exits are weak points because they were not sealed properly and allow humid salt-laden air to enter.
Sediment and scale
High humidity and the marine environment accelerate chemical corrosion of cement and metals.
The pipe entries
The foundation and floor show cracks from minor movement, pressure and thermal expansion cycles with seasonal changes.
The hatch and the vent
Sterilisation is essential here because salt and moisture promote algae and bacterial growth during high-humidity periods.
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.
What is different about Dhahban Sub-Municipality
Dhahban sub municipality is the northern coastal strip of Jeddah, running from the north bank of Sharm Obhur up to the old village of Dhahban and Salman Bay. Its districts are recently built, with owner occupied villas and apartments, beach resorts and chalets on the shore, and land subdivisions still being developed. Nearness to the sea keeps humidity high all year, irrigated lawns in villas, resorts and district parks hold water, Wadi Obhur and the vacant plots between buildings give rodents and reptiles shelter, and the old fishing village of Dhahban gives the far north a rural edge.
Questions about this district
Does sea salt affect tanks even if they sit away from the shore?
Yes. Salts travel in the air and reach considerable distances. Even villas and buildings set back a little show faster decay than inland quarters.
Does new sealing need routine maintenance in Al Shira?
Yes. The marine environment is harsh and sealing degrades faster. Annual inspection and small crack repair is more critical here than elsewhere.
What is the difference between repairing a tank and full sealing?
Repair addresses existing cracks only. Full sealing cleans the whole surface, covers the full face and protects against new corrosion.
Do new tanks in new villas need sealing?
They may. The builder may not apply full sealing during initial construction, and the marine environment starts corroding immediately.
How long does tank sealing take in Al Shira?
It depends on tank size and surface condition. Removing salt deposits and debris takes longer in coastal areas.
Can we seal a tank without fully draining it?
No. Complete drainage is necessary to clean the surface properly, repair cracks correctly and apply effective sealing.
How much does water tank sealing in Al Shira 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 Shira.
