Water tank sealing in Al Rabwah Jeddah
Al Rabwah is an established district in north Jeddah containing villas on large plots alongside apartment blocks. Roof tanks are numerous and many are old, with cracks and leaks common at joints and pipe entries. Sealing and lining here protects buildings from moisture damage to foundations and walls.

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 Rabwah
Tanks in Al Rabwah range from relatively modern to very old, and large villas contain bigger tanks more prone to cracking than smaller tanks in apartment blocks. The method is set out in full on the full Water tank sealing page.
Large tanks on villa roofs
Villas in Al Rabwah contain large tanks exposed to harsh sun year-round. Daily temperature swings cause cracks in tank walls and floor-to-wall joints.
Pipe joints and entry points are weak
Old tank pipe entries and exits were never sealed properly. Joints and holes around pipes are the first places water escapes.
Shared tanks in apartments need regular inspection
Apartment buildings share one or more roof tanks, and high water pressure plus constant use speeds deterioration. Floors and walls wear faster in shared tanks.

Open in Google MapsWhat we read before any material is opened
A mixed district combining villas and apartment buildings in northern Jeddah, lying between King Fahd Road and Prince Majid Road and south of Hira Street, bounded by Al Bawadi to the west and Al Marwah to the east.
Cracking in the wall
Wall inspection searches for vertical and horizontal cracks and hairline fractures from thermal expansion.
The floor to wall joint
Floor and joint inspection focuses on floor-to-wall corners where moisture and pressure concentrate.
The condition of the old lining
Pipe entry and exit inspection looks for leaks around old holes and joints.
Sediment and scale
Inspection of old paint and coatings determines whether they are porous or sealed.
The pipe entries
Exterior roof and side inspection searches for deep cracks and visible seepage.
The hatch and the vent
Inspection of water quality and sediment determines whether salts and rust are building inside.
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 Rabwah
Mixed district: shops at street level with homes above them
Al Rabwah is mixed-character, combining villas on large plots with packed apartment blocks, meaning tanks vary widely in size and age. Large villas hold large tanks needing more care, and apartments have shared tanks under constant pressure. Treatment differs by tank size, age of lining, and original materials.
Questions about this district
Do small tank cracks need full lining or simple repair?
Small cracks may signal deeper deterioration. Full inspection determines whether lining is needed or targeted patching is enough.
Why do large villa tanks crack faster than apartment tanks?
Large tanks bear higher water pressure and endure greater heat swings, causing cracks in walls and corners.
Does lining prevent leaks from old pipes?
Lining protects the tank itself, but old pipes may need separate replacement if they are the leak source.
What is the expected lifespan of new lining in Al Rabwah?
Good lining lasts several years, but high heat and direct sun gradually shorten its life.
Are shared apartment tanks different from individual villa tanks?
Yes. Shared tanks operate under higher pressure and require more thorough inspection and more durable lining.
Must the tank be completely emptied during repair?
Yes. The tank must be empty so we can inspect the floor and walls and apply new lining throughout.
How much does water tank sealing in Al Rabwah 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 Rabwah.
