Water tank sealing in Al Sanabel Makkah
Al Sanabel is a relatively modern residential district made up of apartment buildings on a tight regular grid. Water tanks in these buildings face constant pressure from heavy daily use and thermal cycling. Cracks and leaks appear quickly in older tanks, particularly at pipe entries and internal corners.

Why the job is different in Al Sanabel
Most apartment buildings in Al Sanabel were built within close timeframes and are between 15 and 30 years old. Rooftop tanks face direct sun exposure and leaks appear repeatedly. The method is set out in full on how we approach Water tank sealing.
Tanks exposed to direct sun on building roofs
Most buildings in Al Sanabel have open rooftop tanks. High heat and constant expansion and contraction weaken the material, and cracks start at corners and floor seams.
Pipe entries and joints are the main weak points
Inlet, outlet and overflow pipes create multiple openings in tank walls and floors. Daily vibration and loading stress these joints and cause chronic leaks.
Heavy continuous use from multi-storey residential occupancy
Each building houses dozens of flats with heavy and constant water consumption. High water pressure, repeated filling and draining accelerates internal surface degradation.
The character of Al Sanabel
Apartment district: residential blocks, repeated floors and shared entrances
Tall residential apartment blocks in Al Sanabel mean large tanks under continuous heavy water pressure. Metal and concrete tanks face direct sun and rapid thermal cycling, so the sealant must withstand heavy daily use and repeated filling and drainage cycles.
What we read before any material is opened
A densely packed residential district of apartment buildings on a regular street grid, bounded by King Khalid Road to the east, the Third Ring Road to the north and Muzdalifah Road to the south. It contains neighbourhood mosques, parks and government offices.
Cracking in the wall
Internal surface cracks are visible under direct sun and thermal cycling of metal and concrete tanks on rooftops.
The floor to wall joint
Floor leaks occur at weak joints where the tank floor meets the walls and at internal corners.
The condition of the old lining
Inlet, outlet and overflow pipe openings are chronic leak sources, especially at joints and connection points.
Sediment and scale
Internal moisture builds from heavy use, repeated filling and drainage cycles, and condensation, adding pressure on the internal surface.
The pipe entries
Sterilisation after repair is essential because multi-storey residents need safe clean water from day one.
The hatch and the vent
Advanced cases require inspection of inlet and outlet pipes and the overflow box to rule out additional external leaks.
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 Aziziyah (Makkah) Sub-Municipality
Al Aziziyah sub municipality runs from the Bin Dawood markets to the Al Hada road and carries pilgrim traffic to Mina. Hotel towers and furnished apartment blocks fill and empty with the Hajj and Ramadan seasons, and the kitchens, restaurants and markets along Al Masjid Al Haram Road and King Abdulaziz Road leave food waste at every peak. Southwards the fabric loosens into villas and planned streets in An Naseem and Al Awali, then Al Abidiyah's campus and the old farms of Al Husayniyah, where Wadi Uranah holds water after rain and farm enclosures shelter rodents and reptiles.
Questions about this district
Why does the tank leak from both the floor and walls at the same time?
Cracks usually start at high-pressure points, and pipe openings are the weakest spots. If the tank is old, the material weakens uniformly and leaks appear from multiple locations.
Does cleaning the tank alone stop the leak?
Cleaning removes sediment but does not stop leaks from cracks and weak joints. Sealing the internal surface is needed for a lasting repair.
What drives up the cost of tank sealing in apartment blocks?
Tank size is large and must be fully drained. Multiple pipes need repair, and roof access may require special equipment in tall buildings.
Is a small patch repair enough for a minor leak?
No. A minor leak today can become a major one. Full tank sealing offers long-term protection.
Does tank sealing differ because the building is a tall residential structure?
Yes. Water pressure is higher and use is heavier, so the sealant must withstand greater pressure and mechanical loading from daily heavy consumption.
How long does sealing a residential block tank take?
Usually one or two days depending on tank size and number of pipes. Drainage, repair, sealing and sterilisation are sequential steps.
How much does water tank sealing in Al Sanabel 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 Sanabel.
