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

Describe what you see
Call or message us on WhatsApp and tell us the tank type, where it sits and what you have noticed, whether a leak or damage to the inner surface.

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.
Why combine cleaning and waterproofing in one job

- We use waterproofing materials suited to water tanks
- We take your request by phone call or WhatsApp message
The service in Al Ahsa
In a city like Al Ahsa, homes rely on overhead and underground tanks to store water, and tanks are often prone to leaks from cracks or poor lining. Deep cleaning removes deposits, salts and bacteria from the tank floor and walls, and this removal is essential for strong adhesion between the surface and the new waterproof layer. After cleaning all cracks, joints and corners are checked, then the waterproof layer is applied on a clean, dry surface. The initial inspection determines whether the leak is from the walls, floor or joints, and this shapes the work plan.
Al Ahsa is a city in Al-Ahsa governorate in the Eastern Province, close to As Saifa District, Ayn Najm District and Al Muhammadiyah District.
Salts from ground water in Al Ahsa build up inside the tank and weaken the lining, so cleaning before waterproofing extends the tank's life.

Questions about Tank cleaning & waterproofing in Al Ahsa
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 brown or grey deposits on the tank floor, an odd smell from the water, or a persistent leak with no visible cracks, the tank needs deep cleaning before waterproofing.
Cleaning removes salts and deposits from inside the tank, and waterproofing applies a tight water-resistant layer on the walls and floor to prevent leaks. Cleaning comes first because waterproofing does not work on a dirty or damp surface.
