Water tank sealing in Al Rawdah Jeddah
Al Rawdah is a prestigious residential quarter in northern Jeddah dominated by upmarket villas, modern apartment blocks and contemporary commercial centres. Water tanks in the elegant properties here are large and need precise maintenance because the buildings are relatively new and owner expectations are very high. Seepage or contamination affects property reputation and investment value.
-
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 Rawdah
Most buildings date from the last thirty years or newer, and tanks are designed to better standards but continuous pressure and heavy use accelerate concrete fatigue. The method is set out in full on what Water tank sealing involves.
Upmarket villas with large tanks
Villas in Al Rawdah are spacious and carry large tanks on elevated roofs. Larger volume means greater hydrostatic pressure and higher risk of cracking than in smaller villas.
Commercial centres, modern buildings and heavy use
Shopping centres, hotels and modern residential blocks consume water in large volumes throughout the day. Tanks bear constant and very high pressure, and fatigue appears sooner.
Modern standards but high owner expectations
Tanks are built to better current standards but owners expect zero seepage or contamination. Any minor issue affects property reputation and real estate value.

Open in Google MapsWhat we read before any material is opened
An upmarket residential quarter in northern Jeddah on Madinah Road, bordered by Al Faisaliyah, Al Khalidiyah, Al Salamah and Al Zahra, with luxury villas, modern apartment buildings and Tahlia Street as the commercial spine.
Cracking in the wall
Partial cracking in modern tank walls from continuous hydrostatic pressure and heavy load.
The floor to wall joint
Cracking around pipes and openings from movement and pressure variation at entry and exit points.
The condition of the old lining
The floor-to-wall joint in large tanks faces more pressure than in small tanks.
Sediment and scale
Coastal humidity and heat weaken concrete even in modern tanks at a steady pace.
The pipe entries
Lining requires completely clean surface free of algae, salt deposits and dirt.
The hatch and the vent
Heavy and continuous commercial use accelerates tank fatigue.
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 Al Rawdah
Mixed district: shops at street level with homes above them
Al Rawdah has upmarket villas and modern buildings, and owners here expect high quality with no problems. Tanks are relatively new but continuous pressure and heavy commercial use increase crack risk. Treatment demands high precision and superior finish standards.
Questions about this district
Are modern tanks in Al Rawdah sealed or do they need additional protection?
Modern tanks are better than old ones but not completely sealed. Continuous pressure and coastal humidity cause cracking even in new tanks.
How long does lining last before it needs repair again?
Proper lining lasts five to ten years depending on pressure and use. Tanks with heavy commercial use may need attention sooner.
Does tank size affect sealing cost?
Yes. Larger tanks need more material and more labour, so cost scales with volume.
Can residents stay in the villa during tank repair?
Possible but there will be water outage during draining and cleaning. Usually takes one or two days depending on tank size.
Do modern buildings need different sealing than villas?
Yes. Buildings have much larger tanks and far more pressure. Villas usually have smaller tanks with less pressure but higher quality expectations.
Does lining protect against contamination and algae?
Lining greatly reduces contamination and prevents algae growth on surfaces. Regular cleaning and inspection remain necessary.
How much does water tank sealing in Al Rawdah 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 Rawdah.
