Water tank sealing in Al Mursalat Makkah
Al Mursalat is a dense quarter of pilgrimage hotels and apartment blocks along Al Masjid Al Haram Road, and its tanks face intense pressure from guest and resident water use. Salt-laden air from the nearby port accelerates tank wall corrosion and joint failure, with cracks appearing at the floor, wall-floor joint and pipe entries.

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.

Why the job is different in Al Mursalat
Tanks here serve large residential blocks and pilgrimage hotels, meaning very high water turnover and constant stress on walls and floor joints. The method is set out in full on what Water tank sealing involves.
Heavy-use tanks in pilgrimage hotels
Hotels in Al Mursalat refill tanks several times daily. Repeated water pressure causes cracks at joints and corners, especially in older tanks.
Rapid corrosion from salt air and high moisture
Proximity to the port creates very high humidity and airborne salt. Internal tank walls corrode fast and old sealant layers crack and leak.
Multiple pipe connections and entry points
Large hotels need multiple inlet and outlet pipes. Each entry point is a weak spot where water can seep.
Landmarks of Al Mursalat
Access to hotels and apartment buildings in Al Mursalat runs via Al Masjid Al Haram Road and King Khalid Road, with the Saudi National Hospital and East Aziziyah health centre as key landmarks.

What we read before any material is opened
An eastern quarter south of Al Aziziyah and hard against the port side, cut through by King Khalid Road and close to the Fourth Ring Road. Residential buildings and pilgrimage hotels overlook banks, restaurants and shops along Al Masjid Al Haram Road.
Cracking in the wall
Floor cracks appear at corners and under high-pressure zones where water pools.
The floor to wall joint
Wall cracks concentrate at the wall-floor joint and at multiple pipe entry points.
The condition of the old lining
Leaks from pipe connections come from failed original filler and corrosion around inlet and outlet holes.
Sediment and scale
Old sealant layer cracks and peels from salt-water exposure and continuous high humidity.
The pipe entries
External wall moisture means water seeps in from outside through hairline cracks.
The hatch and the vent
Failure to sterilise after repair means water may carry bacteria or algae growing on the new surface.
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 do Al Mursalat tanks leak more than other quarters?
Port proximity raises humidity and salt in the air, speeding sealant corrosion. Heavy hotel use adds constant water pressure.
Can cracks be repaired without emptying the tank?
No. Internal cracks at the floor and walls need full surface cleaning and drying before repair and sealing can work.
How often does the tank need resealing in this area?
Roughly every 8 to 10 years because sealant corrosion is faster here than in districts away from the coast.
Do multiple pipe connections need special handling?
Yes. Each pipe entry needs special filler and an extra sealant layer around it to stop leaks.
What drives rapid corrosion in tanks here?
Salt water in the air, high humidity and constant water pressure from heavy use all work together to corrode the sealant and concrete.
Is sterilising the tank after sealing necessary in this area?
Yes, critically. High humidity and salt may cause algae and bacteria growth, and sterilisation ensures safe water for use.
How much does water tank sealing in Al Mursalat 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 Mursalat.
