Water tank sealing in Al Jumayzah Makkah
Al Jumayzah is a small, dense district close to the Grand Mosque along Al Masjid Al Haram Road and Al Hajoun Street. The buildings are medium-rise apartments and small hotels for Umrah visitors, with tanks mounted on modest rooftops, but they are old. Water seeping from worn tank lining enters shared passages and walls adjacent to the Holy Mosque.

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.

Ground and roof tanks
Villas, apartment blocks and premises that need a written record of each visit.
Why the job is different in Al Jumayzah
Most buildings are medium-rise, built in the mid-20th century or earlier, with modest-sized tanks on low roofs, but the tanks are very old and lining is heavily corroded. The method is set out in full on Water tank sealing in detail.
Old tanks on modest residential rooftops
Small apartment blocks and hotels in Al Jumayzah have medium-sized tanks on modest roofs. The tanks were installed 50 years ago or longer and the original lining is completely degraded.
Narrow shared passages and concentrated moisture
Shared corridors between apartments are narrow and poorly ventilated. Water leaking from the tank runs down into these passages causing permanent dampness and heavy mould growth.
Proximity to the Mosque demands higher hygiene standards
The quarter lies very close to the Grand Mosque and adjacent mosques. Religious standards for purity and cleanliness demand water that is completely clean, free of dampness and mould in all buildings.
Landmarks of Al Jumayzah
Al Jumayzah is bounded by important historic landmarks: the Al Mualla cemetery to the east, the Grand Mosque to the north, and Masjid Al Jinn and Al Saqqaf Palace to the south, which precisely define building locations.

What we read before any material is opened
A small dense district near the Grand Mosque, along Al Masjid Al Haram Road and Al Hajoun Street, named after the sycamore fig tree where residents once gathered. It is bounded by the Al Mualla cemetery to the east and historic mosques and palaces to the south.
Cracking in the wall
Cracks in the very old tank leak from everywhere and degraded lining cannot protect the internal surface.
The floor to wall joint
Joints around pipe entries fail first because they are the weak points in tanks of this age.
The condition of the old lining
The tank's inner surface is corroded from water, mineral deposits and rust from old iron pipes.
Sediment and scale
Humidity is consistently high in shared passages and internal walls are always damp.
The pipe entries
The primary leak source is the tank itself: cracks and deteriorated joints distributed across the entire structure.
The hatch and the vent
Seeping water pools in lower passages, lower ceilings begin to peel and mould grows rapidly.
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 Maabdah Sub-Municipality
Al Maabdah sub municipality climbs from Al Abtah and Al Jumayzah beside the Al Mualla cemetery up through Al Khansa and Rai Adhakhir to Al Adl, Jabal Al Nour, Wadi Jaleel and Qurtubah on the outer ring roads. It mixes hotels and pilgrim housing near the Grand Mosque with old popular houses on hillside passes, new housing schemes on valley floors that carry flash floods after rain, and industrial plots, workshops and warehouses along Al Hajj Street in Qurtubah. Street widening and expropriation leave partly demolished frontages in Al Khansa.
Questions about this district
Does tank seepage affect apartments directly adjacent to the Sanctuary?
Yes. Seeping water percolates into shared passages and walls in buildings immediately next to the Mosque.
Why are tanks in Al Jumayzah so old?
The district is old and many buildings date to mid-20th century; the original tanks have never been replaced.
Is dampness in shared passages a health risk?
Yes. Moisture and mould cause respiratory problems and allergies, especially for pilgrims and visitors.
Do Mosque-proximity hygiene standards demand stronger sealing?
Yes. Water must be absolutely pure with no dampness or mould, so lining quality must meet religious and health standards.
Does one tank serve many apartments in Al Jumayzah?
Yes. A single tank may serve 10-20 apartments or more, so one leak affects dozens of families.
Does fixing the tank solve dampness in passages or is the problem deeper?
Fixing the tank stops the main source, but drying passages and walls after repair may be needed.
How much does water tank sealing in Al Jumayzah 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 Jumayzah.
