What tank cleaning and waterproofing includes
- Fully emptying the tank and removing sediment and residue from its walls and base
- Rinsing the inner walls until the surface is clean and ready for inspection
- Checking the tank walls, base and joints for cracks or damage to the inner lining
- Treating cracks and joints and preparing the surface before any waterproofing material is applied
- Applying the right waterproofing layer to the walls, base, edges and corners
- Giving special attention to the joints between walls and base, which are often the most vulnerable points

Emptying and cleaning the tank
The tank is fully emptied, then the sediment and residue clinging to its walls and base are removed, and it is rinsed until the surfaces are clean and dry.

Repairing cracks and preparing the surface
Cracks and joints are treated before any coat is applied, because a waterproofing material does not bond to a cracked or wet surface. A good layer starts with a surface that is ready.

Applying the waterproofing layer
The right waterproofing material for the tank, such as epoxy or bitumen, is applied to the walls, the base and the corner joints, with careful attention to edges and seams.
Why combine cleaning and waterproofing in one job
- Waterproofing over a dirty surface separates quickly
- We treat cracks before any coat is applied
- We check all the tank walls while cleaning
- We use waterproofing materials suited to water tanks
- We take your request by phone call or WhatsApp message
The service in ’Uray’irah
In a village like 'Uray'irah, most homes have tanks on the roof or in the yard, filled from a well or the mains. Water that leaks from cracks in the lining, from the tank bottom or from the joint between wall and base is lost water and wasted money. The old lining, especially bitumen, may crack from heat and dryness or from slight tank movement. Work starts by cleaning the tank of silt, rust and old paint, then cracks and splits are inspected, and finally a new waterproof lining of epoxy or bitumen is applied over the prepared surface.
'Uray'irah is a village in Al-Ahsa governorate in the Eastern Province, close to UmmTali, Umm Rubay'ah and Umm al Hamam.
The joint between the tank wall and its base is where leaks first show, because water pressure builds there.

Questions about Tank cleaning & waterproofing in ’Uray’irah
Cleaning is a necessary step before waterproofing. The material needs a clean, dry surface to bond to. Any sediment, algae or residue between the wall and the coat causes it to separate quickly. Waterproofing alone without prior cleaning does not solve the problem.
Epoxy is a resin that hardens after application and forms a rigid layer that resists water and wear; it is often used to line indoor water tanks. Bitumen is a flexible rubber-like material or comes as a rolled membrane fixed to the surface, and suits different conditions. The choice depends on the tank type and the state of its walls.
It is not advisable. A crack in a tank wall moves with heat expansion and contraction, and any coat applied over it without treatment will crack again at the same spot. Treating cracks and joints before applying the waterproofing is the step that keeps the layer in place over time.
Yes, full emptying is necessary for both steps. The walls and base cannot be cleaned properly with water still inside, and a waterproofing material cannot be applied to a wet surface. After the coating is applied, the surface needs enough time to dry before the tank is refilled.
Tell us the tank type, ground or overhead, and whether it is concrete or plastic, and what you have noticed: a leak from a wall or the base, a crack in the inner lining, or an odour in the water. The clearer the details, the better we can judge what the tank needs before we arrive.
If you see wetness or a damp patch on the roof or wall under the tank, or notice the water level drops without use, there is a leak. Call us to inspect the tank and find where it is coming from.
Yes, the tank is completely emptied first, then cleaned inside to remove all silt, rust and old paint, and then the new waterproof layer is applied over a clean, dry surface.
