Water tank sealing in Al Bashair Jeddah
Al Bashair is a new district on the north Asfan ring road, with villas and apartments built in recent years on slightly elevated ground. Tanks here face distinct challenges: heavy clay soil exerts lateral pressure on tank walls, and intense heat causes rapid water expansion. Weak points typically form at corners and lower joints where pressure concentrates.

Why the job is different in Al Bashair
Most villas and apartments in Al Bashair were built on elevated land over dense clay soil, and tanks show leaks from the base and sides due to lateral pressure from the clay. The method is set out in full on our Water tank sealing service.
Lateral pressure from heavy clay soil
Al Bashair is built on dense clay that presses from the sides on tanks. Lateral pressure causes cracks in side walls and leaks at corners.
Rapid water expansion and high heat
The area is open and faces direct sun. Water in tanks expands quickly with high temperature, and expansion pressure causes additional cracks and leaks.
Deep tanks and lower joint stress
Villas and apartments here have deep tanks because the land is slightly elevated and water needs pumping. Lower joints bear double pressure from water weight and lateral soil pressure.
The character of Al Bashair
New development: ongoing construction and vacant plots between the homes
A new district on heavy clay soil means tanks face continuous lateral pressure in addition to heat and expansion. Treatment focuses on strong internal reinforcement and tight external sealing to handle dual pressure loads.
What we read before any material is opened
A newly developed district in north Jeddah on the Asfan ring road, with Al Furusiyah Road on its east, Taybah to the west, Al Falah to the south and Al Rahmaniyah to the south east. Recently built villas and apartment buildings sit beside subdivisions still under construction.
Cracking in the wall
Water in new tanks retains very high heat in summer, and thermal expansion causes strong internal pressure on walls.
The floor to wall joint
Heavy clay soil around tanks exerts continuous lateral pressure, especially after rain when soil absorbs water.
The condition of the old lining
Lower joints and corners are first leak points because lateral pressure concentrates there.
Sediment and scale
Soil moisture penetrates external sealing if not perfectly tight, especially at joints.
The pipe entries
Vertical cracks in walls are from thermal expansion; horizontal cracks are from lateral pressure.
The hatch and the vent
Clean water needs protection from external moisture and dirt that may enter through cracks and gaps.
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 Taybah Sub-Municipality
Taybah sub municipality covers the newly built districts of north east Jeddah along Al Haramain Road and Asfan Road. New villas and apartment buildings stand among vacant plots, building sites and half finished subdivisions. Al Hamdaniyah is the oldest and densest part with its markets and shops, while Al Furusiyah, Al Bashair, Al Rahmaniyah, Al Falah and Al Salihiyah are mostly recent. The ground is inland and away from the sea, dry and dusty, rest houses, camps and stables on the fringes draw flies and crawling insects, and constant digging and construction stirs rodents out of the empty plots.
Questions about this district
Why do leaks in Al Bashair occur from the base and sides rather than the top?
Heavy clay soil presses laterally on tanks, and lateral pressure causes leaks at corners and lower points.
Does higher heat in Al Bashair cause more cracks than other areas?
Yes. The area is open and sun hits tanks directly, water expands quickly and internal pressure increases.
What is the difference between repairing deep and shallow tanks?
Deep tanks need stronger lining because water pressure is greater and lower joints need special attention.
Does external sealing protect against lateral soil pressure?
Only partly. External sealing protects from water but lateral clay pressure causes internal cracks that external sealing may not prevent.
Do we need both external and internal protection in Al Bashair?
Yes. Complete treatment needs external sealing and strong internal lining to handle lateral pressure and thermal expansion.
How long until leaks return if lateral pressure is not addressed?
Leaks may return within weeks if lateral pressure remains, because new cracks will form from ongoing pressure.
How much does water tank sealing in Al Bashair 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 Bashair.
