Water tank sealing in West Al Baghdadiyah Jeddah
West Al Baghdadiyah sits directly on Jeddah's waterfront, and tanks here stand on low, flat ground close to stagnant water and wetland. Salt and high moisture attack concrete from below and above at once. Mid-century apartment blocks hold tanks with continuous leaks from cracks caused by coastal subsidence.

Why the job is different in West Al Baghdadiyah
The ground here is low and close to the water table, and tank foundations sit in wet, saline soil. The method is set out in full on the full Water tank sealing page.
Tanks on low, waterlogged ground
The flat coastal terrain means tanks sit very near the water table and stagnant water. Moisture enters from the side and floor at once, and foundations sink into saline soil.
Coastal subsidence and accelerated decay
Sand and gravel shift fast under building weight. Tanks bend and crack, the lining breaks from movement and salt speeds corrosion.
High moisture and salt spray year-round
The coastal climate here is very wet and sea salt is in the air constantly. Interior lining corrodes from saline acidity and unbroken moisture.
The character of West Al Baghdadiyah
Coastal area: high humidity and salt air through the year
The coastal setting means tanks face hydraulic pressure from a high water table. Treatment must focus on both exterior and interior sealing, not just interior lining as in inland areas.
What we read before any material is opened
A coastal quarter on the water side of Madinah Road, between Port Bridge Road and the sea, close to the Arbaeen lagoon, the old corniche and historic Jeddah. Apartment buildings and mid-century blocks fill the low-lying shore.
Cracking in the wall
Floor cracks start from saline groundwater pressure pushing inward from below.
The floor to wall joint
Cracks around the tank sides leak because hydraulic pressure tests the concrete continuously.
The condition of the old lining
Pipe entry points leak because downward movement and lateral pressure fracture the concrete around pipes.
Sediment and scale
Salty, damp air from the sea and groundwater cause rapid acid corrosion in concrete and lining.
The pipe entries
Shallow foundations in wet soil settle and bow, causing shear stress and cracking in tank walls.
The hatch and the vent
Water seeping from the floor is a key sign of high groundwater pressure, not just weak lining.
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 Al Balad Sub-Municipality
Al Balad sub municipality covers the historic core of Jeddah and the districts that first grew outside its wall. Its building stock is the oldest in the city: heritage stone houses and apartment blocks from past decades, threaded with hotels, shops and crowded popular markets around Bab Makkah, Bab Sharif and the Kandarah Souq. Nearness to the sea, the Islamic Port and the Arbaeen lagoon keeps humidity high all year, water and drainage networks are old, and narrow lanes, dense eateries and commercial storerooms put food and shelter within reach at every corner.
Questions about this district
Why does the tank in West Al Baghdadiyah leak from floor and sides at once?
Low ground means the water table is very high. Hydraulic pressure from outside pushes water into the tank through cracks.
Does a high water table mean the tank needs sealing on the outside too?
Yes. In this coastal area, the floor and sides must be sealed from outside as well to keep saline groundwater out.
Can the new lining withstand the pressure of saline groundwater?
The right lining can if thick and strong. But if foundations are settling, the new lining may crack as the structure moves.
How often do coastal tanks need re-sealing?
Coastal tanks need inspection and re-sealing every two years. Lining deteriorates faster here than in inland areas.
Does sea salt change how the tank is cleaned and sterilised?
Yes. Sterilisation must be stronger here. Salt and bacteria linked to the coastal setting need a specific sanitiser.
Would rebuilding foundations solve the groundwater problem?
It might if built deeper with full sealing. But if the water table stays high, ongoing sealing will still be needed.
How much does water tank sealing in West Al Baghdadiyah 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 West Al Baghdadiyah.
