Water tank sealing in South Prince Fawaz Jeddah
South Prince Fawaz is a densely built residential extension in south Jeddah crossed by an open stormwater channel. Tanks here are exposed to silt and dust from the channel and seasonal runoff, and both apartments and villas need regular inspection for leaks and cracking caused by rising moisture.
-
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 South Prince Fawaz
Most buildings here were built 15-20 years ago, and tanks suffer from silt deposits and salt accumulation from groundwater and seasonal drainage. The method is set out in full on the full Water tank sealing page.
The open stormwater channel raises moisture and contamination
The channel runs alongside the district and raises humidity around foundations and ground-level tanks. Mud and sand particles enter the water when the channel floods in seasonal rain.
Ground tanks beneath villas and apartment blocks are leak-prone
Most new villas and apartment blocks have ground tanks set below the foundation slab or in a courtyard. Concrete cracks and groundwater pressure cause slow seepage.
Salty groundwater erodes weak linings
Groundwater here carries high salt content. Old or poorly applied linings break down quickly under chemical attack.

A mixed residential quarter in south Jeddah close to Haramain Road and the Jeddah-Makkah Expressway, divided by an open stormwater channel running parallel to the main street.
Cracking in the wall
Floor inspection focuses on fine cracks and slow seepage from groundwater pressure and salt ingress.
The floor to wall joint
Floor-to-wall corners show cracks because concrete shrinks unevenly under alternate wetting and drying.
The condition of the old lining
Pipe entries and the main inlet and outlet are usually the first leak points.
Sediment and scale
Salty groundwater penetrates through the lower floor and side walls under pressure.
The pipe entries
Slow seepage occurs below the waterline where hydrostatic pressure is highest.
The hatch and the vent
Silt and sediment accumulate on the floor and block corners, causing stagnant zones and seepage paths.
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.
The character of South Prince Fawaz
Mixed district: shops at street level with homes above them
The district mixes small villas and newer apartment blocks, so tanks vary in size, depth and position. Villas typically have one shallow ground tank, while apartment blocks may require checks at multiple points and additional rooftop tanks.
Questions about this district
Is the stormwater channel the cause of tank leaks?
It may contribute. Rising groundwater pressure alongside the channel pushes against tank walls from outside.
Is slow tank seepage normal in this district?
Not normal but very common here. Groundwater and salt corrosion attack linings that do not meet proper sealing standards.
What determines the cost of tank repair?
Crack size and depth, seepage severity and condition of floor and corners. Large tanks with multiple leak points need longer treatment.
Does a new lining protect against foul groundwater?
Yes. A tight lining seals the tank from all external moisture and salty groundwater.
Do villas and apartment blocks need different tank inspection?
Yes. Villas usually have one deep ground tank, while apartment blocks may have a ground tank and an additional rooftop tank.
How often does resealing need to happen?
A good seal lasts 10-15 years. But in this district, due to high moisture and salt, inspection every 5 years is wise.
How much does water tank sealing in South 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 South Prince Fawaz.
