Water tank sealing in North Prince Fawaz Jeddah
North Prince Fawaz is a mixed residential and commercial extension in south Jeddah served by large markets and shops along main axes. Tanks here experience heavy water consumption from both retail and domestic use, and the sustained pressure on the system accelerates wear and cracking.
-
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 North Prince Fawaz
The district is served by large retailers including Al Othaim and numerous local shops, placing continuous heavy demand on water systems and tank capacity. The method is set out in full on our Water tank sealing service.
High consumption from markets and shops strains tank pressure
Al Othaim Markets and local retail shops demand large volumes of water throughout the day. Sustained high pressure and frequent cycling of water pipes and tank walls cause multiple cracks.
Rooftop tanks on older buildings are worn and at risk
Older residential apartment blocks have rooftop tanks exposed to sun and heat. Old linings crack and peel from repeated expansion and contraction cycles.
Shops and retail premises need intensive regular inspection
Retail shops and small hotels do not always monitor tanks consistently. Slow seepage in these locations can weaken adjacent foundations or raise moisture around the building.

What we read before any material is opened
The northern half of Prince Fawaz in south Jeddah, bounded by Muhammad ibn Sahmi Street to the north with Al Adl beyond, Al Fadl to the east, containing apartment buildings and mid-sized villas with shops and markets on main streets.
Cracking in the wall
Floor inspection reveals cracks and seepage from sustained high pressure driven by retail water demand.
The floor to wall joint
Tank corners show multiple cracks as pressure concentrates on structural weak points.
The condition of the old lining
Multiple pipe entries in retail tanks mean multiple water input points and higher leak risk.
Sediment and scale
Moisture around rooftop tanks is very high from leaking water and condensation dripping.
The pipe entries
Sediment in retail tanks builds up quickly because high consumption continually disturbs settled deposits.
The hatch and the vent
Rooftop tank seepage can damage the whole building if not repaired promptly.
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 Sub-Municipality
The South sub municipality runs from the edge of Old Makkah Road down to Al Khumrah and the southern corniche. Dense residential districts sit beside new subdivisions such as Al Sanabil and Al Taawun, warehouse fringes such as Al Saruriyah and Al Sarawat, and an old seaside settlement at Al Quzayn. Open stormwater channels cross the housing, and the warehouses, the vegetable and livestock markets and the nearby Islamic Port and Industrial City give pests shelter, food and year round humidity. Pressure is greatest in the older quarters, where drainage networks are ageing.
Questions about this district
Do large markets consume more water than residents?
Yes, far more. Markets use water for cleaning, toilets and cooling, often consuming double the volume of domestic use.
Why do rooftop tanks crack faster than ground tanks?
Rooftop tanks face direct sun, heat and cold. Daily cycles of expansion and contraction degrade the lining quickly.
What is the main cost driver for tank sealing?
Tank size, number of cracks and lining type. Large retail tanks are more expensive than residential units.
Is one tank sufficient for a small retail shop?
Depends on demand. Small shops may use one tank, but large retailers need multiple reserves.
Does tank lining affect water quality in shops?
Yes. Poor lining allows contaminant seepage and off-taste in the water.
How often should retail and shop tanks be inspected?
At least annually due to high consumption. Busy retail sites should be checked every 6 months.
How much does water tank sealing in North Prince Fawaz 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 North Prince Fawaz.
