Water tank sealing in Al Ukayshiyah Makkah
Al Ukayshiyah is a mixed district in southern Makkah below the Fourth Ring Road, undergoing continuous paving, sewerage works and informal building clearance. Tanks here face pressure from unstable soil movement, weak foundations and moisture from adjacent construction activity. Sealing and repair must account for the shifting ground and ongoing foundation settlement.
-
Potable-rated materials
Linings and disinfectants cleared for drinking water tanks, not general-purpose products.
-

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.

Villas, apartment blocks and premises that need a written record of each visit.
Why the job is different in Al Ukayshiyah
Soil here is unstable and moves constantly from construction, excavation and sewerage work, and tanks suffer from ground subsidence and the resulting cracks. The method is set out in full on what Water tank sealing involves.
Weak and informal foundations
Old informal buildings were constructed on shallow, poorly secured bases. Tanks fixed to them shift and tilt with soil movement, causing cracks in the floor and walls.
Adjacent paving and excavation work
Current sewerage and paving operations shake soil around tanks. Continuous vibration from machinery loosens the joints between floor, walls and pipe entries.
Moisture from construction environment and ongoing development
The district is subject to continuous building and excavation and water pools in nearby trenches. High moisture accelerates degradation of the tank's protective layers.
The character of Al Ukayshiyah
Mixed district: shops at street level with homes above them
A mixed district means a blend of old informal buildings, modern constructions and new projects. Tanks here sit on foundations of varying quality and move with the soil. Sealing must account for district instability and ongoing construction activity.
What we read before any material is opened
A mixed district in south Makkah between the Fourth Ring Road and the district roads, bounded by Souq Al Halaqa to the east and Ai Layth and Ibrahim Al Khalil roads passing through. The area is undergoing continual development with many informal buildings under demolition.
Cracking in the wall
Floor cracks usually form in the floor centre where water pressure is highest, and soil movement accelerates their appearance.
The floor to wall joint
Pipe joints are weak because they meet metal and concrete, and vibration from nearby excavation loosens them first.
The condition of the old lining
Inlet and outlet pipes are exposed to sideways movement from uneven soil subsidence beneath the building.
Sediment and scale
High moisture from excavations and sewerage weakens surface protection and accelerates chemical erosion.
The pipe entries
Cracks start small in joints and corners, then grow with continued movement and hydrostatic pressure.
The hatch and the vent
High soil moisture and salts from construction penetrate the concrete and weaken the internal protective layers.
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 Shawqiyah Sub-Municipality
Al Shawqiyah sub municipality runs south from the Third Ring Road to the city's edge on the Al Layth road and the Jeddah expressway. Planned districts such as Al Shawqiyah, Al Malik Fahd and Bathaa Quraish have wide streets, villas and apartment blocks, while schemes in Wali Al Ahd are being built out and informal housing in Al Ukayshiyah and Al Zuhur is being cleared. The vegetable market and livestock auction at Souq Al Halaqa, open construction sites, the rocky slopes of Jabal Thawr and sewers still being laid through the southern fringe offer exposed food, shelter and moisture.
Questions about this district
Why do tanks crack faster in Al Ukayshiyah than other areas?
Soil here is unstable and moves constantly from construction and excavation. Tanks fixed to weak foundations feel every movement and crack.
Is the leak from floor cracks or pipe joint failure?
In Al Ukayshiyah it may be both. Soil movement loosens joints first, and if not repaired, causes floor cracks later.
Do the sewerage works underway affect an existing tank?
Yes. Vibration from excavators and machinery weakens existing joints and fine cracks.
Is surface treatment enough or must the tank be fully drained?
In Al Ukayshiyah the tank must be fully emptied and every crack and joint reached. The outer surface alone will not stop leaks from soil movement.
How often must a tank be repaired if construction continues around the building?
If excavation and building continues nearby, new cracks may appear within months. Repair stops current leaks only and may require periodic checking.
Does the tank need replacing instead of repair?
If cracks are surface and the joints remain structurally sound, repair is sufficient. But if the tank is very old and weak, replacement may be better.
How much does water tank sealing in Al Ukayshiyah 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 Ukayshiyah.
