Water tank sealing in Al Hamra Umm Al Jud Makkah
Al Hamra and Umm Al Jud form a broad western extension along the old Jeddah road hosting large upmarket villas with spacious gardens. Tanks here sit on relatively high ground but seasonal moisture and dry winds cause minor concrete movement. The location between the King Abdulaziz Complex for the Kiswa and the Jeddah expressway and Fourth Ring Road means tanks endure intense heat and repeated temperature swings.
-
Potable-rated materials
Linings and disinfectants cleared for drinking water tanks, not general-purpose products.
-
You get the downtime first
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 Hamra Umm Al Jud
Villas are large with large tanks and the ground is relatively high and rocky with low natural moisture, but tanks are exposed to intense direct sunlight and may suffer thermal movement and cracking. The method is set out in full on how we approach Water tank sealing.
Exposed tanks and intense heat
Tanks in villas are typically exposed on roofs or half-exposed in courtyards. Direct solar heat causes repeated concrete expansion and contraction, with cracks especially at corners and floors.
Upmarket villas and large tanks
Each villa has a large tank, often on the roof or in a large courtyard. Size and direct exposure increase thermal cracking.
Jeddah expressway and vibration
Proximity to the Jeddah expressway and Fourth Ring Road means tanks experience vibration from heavy vehicles and dust and pollutant exposure. Vibration causes gradual minor movement and progressive cracking.
Landmarks of Al Hamra Umm Al Jud
Tank access in Al Hamra and Umm Al Jud runs via the old Jeddah road from the east, and the King Abdulaziz Complex for the Kiswa is a clear landmark on the road. The Jeddah expressway and Fourth Ring Road bound the area from the west, Al Malik Fahd from the south and An Nuzhah from the east.

What we read before any material is opened
A broad western extension along the old Jeddah road in two tracts, Al Hamra nearer the centre and Umm Al Jud further west towards the Jeddah expressway and Fourth Ring Road. Villas predominate, Al Malik Fahd lies to the south, An Nuzhah to the east, and the King Abdulaziz Complex for the Kiswa of the Kaaba stands beside the road.
Cracking in the wall
The base and floor need inspection for fine thermal cracks that may be very small but widen with seasonal swings.
The floor to wall joint
Exposed walls bear most heat and cracks usually start from west and east faces exposed to sun.
The condition of the old lining
The wall-to-floor joint is weakened by thermal movement and cracks concentrate there.
Sediment and scale
Pipe entries and connections may also be sun-exposed and move more than the main tank body.
The pipe entries
Leak sources are usually thermal cracks developing, not weak base or high groundwater.
The hatch and the vent
Repeated thermal movement means cracks widen gradually even after sealing and periodic inspection is needed.
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 Umrah Sub-Municipality
Al Umrah sub municipality covers the north west of Makkah along the Madinah road and the old Jeddah road, from At Tanim and Masjid Aisha to An Nawwariyah. Its districts are the city's newest, villas and apartment blocks raised on wide schemes where large tracts in Al Umrah Al Jadidah, Al Fayha and Al Buhayrat remain vacant or under construction. Wadi Saraf and Wadi At Tanim run through it and rainwater gathers on unfinished schemes, ihram shops, restaurants and coach stops along the Madinah road serve a constant flow of pilgrims, and villas fill Al Hamra and Umm Al Jud.
Questions about this district
Why do thermal cracks appear more in villa tanks than in other buildings?
Tanks are roof-exposed and direct solar heat causes repeated expansion and contraction. Concrete cracks under thermal stress.
Does the location near the expressway damage the tank?
Yes. Vibration from heavy vehicles, dust and pollutants affect concrete and cause gradual cracking.
Can the tank be relocated underground to reduce heat exposure?
Possible but villas typically prefer roof or courtyard tanks. Full relocation would need complete rebuilding.
Does heat-treated concrete resist intense heat better?
Sealing protects against moisture and leaks but does not reduce thermal movement. Cracks may appear even after sealing if heat is very intense.
How much does leaking increase in summer due to heat?
Leaking may not increase directly but thermal cracks widen and create new paths for water to seep.
Does shading or thermal insulation on the tank stop cracking?
Shading reduces heat and thermal movement. But thermal insulation is usually complex and impractical for existing tanks.
How much does water tank sealing in Al Hamra Umm Al Jud 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 Hamra Umm Al Jud.
