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.
- 3
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.

The service in Az Zahrah District
In homes in a district like Az Zahrah, tanks may be rooftop or underground and endure daily use pressure and intense heat. Salt in the Al-Ahsa climate speeds up corrosion, and small cracks in the lining become gateways for water. Before waterproofing begins, the tank must be emptied and deeply cleaned of sediment, algae and rust. Then the inner and outer surfaces, base and joints around pipes are inspected. Once the surface is verified clean and dry, epoxy or bitumen is applied according to the tank's needs. The first inspection guides the right course of action.
Az Zahrah District is a district in Al-Ahsa governorate in the Eastern Province, close to Al Jamiyin District, Al Iskan 1st District and Al Hamra 1st District.
Corrosion and leaks in Az Zahrah tanks usually start from joints and the tank base, where water sits longest.

Questions about Tank cleaning & waterproofing in Az Zahrah District
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.
It completely empties the tank, then cleans it inside and out using specialist equipment to remove sediment, algae and rust. After cleaning, the surface is inspected for cracks or weak points before waterproofing material is applied.
Look below the tank and around its base for damp patches or water pooling on the ground. Listen for dripping or watch for discoloured walls or ground around it. If the water level drops faster than normal, call Al Raya to inspect it.
