Water tank sealing in Al Judairiyah Al Jadid Makkah
Al Judairiyah Al Jadid is a new quarter between Al Souq Al Saghir Al Jadid and Al Hajlah Al Jadid, with new villas built along Al Judairiyah Al Jadid Street. Jabal Al Raqid rises within the district and the land here is rocky and rough. Tanks need strong sealing because they rest on foundations cut into solid rock.
-
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 Judairiyah Al Jadid
Villas were built in the last year on foundations dug deep into solid rock, and tanks sit directly on bedrock and may contain voids beneath the floor slabs. The method is set out in full on the full Water tank sealing page.
Foundations on rock with deep excavation
Jabal Al Raqid is rocky and foundations were dug deep into solid bedrock. Tanks sit directly on bedrock and may contain natural gaps and cracks in the rock beneath them.
Floor slabs built on broken rock
The land in Al Judairiyah Al Jadid is rocky and rough and floor slabs were laid on a bed of gravel and cement over broken rock. This layer may not be perfectly level and the tank may settle slightly.
Harsh sun and voids beneath the tank
The quarter is fully exposed and sun beats down directly on tanks. If voids exist under the floor slab, heat may create air pockets and internal pressure may affect the tank bottom.
Landmarks of Al Judairiyah Al Jadid
Access to Al Judairiyah Al Jadid runs via Al Judairiyah Al Jadid Street, bounded by Al Souq Al Saghir Al Jadid to the north and Al Hajlah Al Jadid to the south, with Jabal Al Raqid as a prominent landmark and the southern Haram boundary marker at its edge.

What we read before any material is opened
A newly built quarter in the Crown Prince scheme south of Jeddah, with new villas spread along Al Judairiyah Al Jadid Street, bounded by Al Souq Al Saghir Al Jadid to the north and Al Hajlah Al Jadid to the south, with Jabal Al Raqid rising within it.
Cracking in the wall
Cracks from uneven pressure distribution result from voids beneath floor slabs and uneven rock surfaces.
The floor to wall joint
Floor-to-wall joints may open if foundations are uneven and water finds its way into corners.
The condition of the old lining
Pipe entries are drilled into solid rock and voids may exist around pipes from the drilling.
Sediment and scale
Groundwater is rare here because the land is rocky, but moisture from rare rain may collect in natural rock cracks.
The pipe entries
The rock beneath the tank may contain natural cracks and small voids and inner sealing protects against water seeping through them.
The hatch and the vent
Water filling the tank for the first time may reveal weak points in rock or floor slabs and initial sterilisation is essential.
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 South Makkah Sub-Municipality
South Makkah sub municipality is the belt of Crown Prince schemes south of Al Ukayshiyah, along the Al Laith road and the extension of Ibrahim Al Khalil Road to the Fifth Ring Road and the Non Muslims bypass. Most of it is still bare: granted plots awaiting houses, new villas standing alone, open building sites and unfinished paving and drainage. Wadi Uranah and its tributaries cross the low ground and hold water after rain, hills close it in, and rodents, reptiles and scorpions shelter in stacked materials and foundation pits before the neighbourhoods fill up.
Questions about this district
Are voids beneath floor slabs common in Al Judairiyah Al Jadid?
Yes, because the land is rocky and floor slabs were laid on gravel and cement. Small voids may exist under the tank.
Do tanks built on solid rock need different sealing?
Yes. Solid rock does not absorb water but may contain natural cracks. Rock must be inspected before building and sealing.
Why do cracks appear from voids beneath the tank?
Voids cause uneven pressure distribution and when the tank fills, pressure concentrates only on strong points and cracks form in weak spots.
Does levelling the floor slab under the tank stop the problem?
It may help, but if voids exist under the foundation itself, levelling alone is not enough and sealing must protect the inner surface.
How do we confirm the rock under the tank is strong enough?
We inspect the rock before construction and check for deep natural cracks. If concerns exist, we build an additional concrete base.
Does heat from Jabal Al Raqid affect tanks more than other areas?
Jabal Al Raqid is close and the sun is fully exposed, so heat is very high. Tanks may expand rapidly and sealing must tolerate fast expansion.
How much does water tank sealing in Al Judairiyah Al Jadid 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 Judairiyah Al Jadid.
