We inspect the tank
We check the walls, the base, the joints and the existing lining to find where water enters and what damage has been caused.
- 3
We prepare the surface and treat cracks
The tank is fully emptied and cleaned, and cracks and joints are treated before any lining work, because a lining cannot do its job over an unprepared surface.

We choose the lining system that suits the tank type and the condition we find, and apply it to the walls and base together until the treatment is complete.

The service in Al Ahsa
In a city like Al Ahsa, water tanks are common on roofs and at ground level, and outer walls often show marks of dampness and salt because groundwater is salty and humidity is high. Leaks may come from cracks in the tank walls or base, or from joints around pipes and openings. The technician inspects the tank for signs of dampness, cracks and leaks, then decides what treatment is needed. Walls, base and joints may need cleaning, drying and coating with a waterproof material depending on where the leak is.
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.
Most tank leaks start at joints and the base, where water pressure and thermal movement combine.

Questions about Water tank waterproofing in Al Ahsa
Inside waterproofing treats the surface that is in direct contact with the water, and it is the most effective way to stop a leak because the lining faces the pressure from the right direction. Outside waterproofing is used when the tank wall is buried or faces soil moisture, and ground tanks are often treated on both sides.
Yes, considerably. A concrete tank has a rigid wall where cracks and joints accumulate over time, and it suits cementitious or epoxy linings designed to bond with concrete. A fibreglass tank has a flexible wall that cracks differently, and needs a resin repair that is compatible with its material.
Before, always. A crack in the tank wall is a direct path for water, and any lining applied over it without prior repair will separate from it or crack with it in time. Repairing the crack first is what allows the lining to do its job.
The base carries the full weight of the water above it, and the joint between the base and the wall is often a structural weak point formed during casting. Moisture also collects in the lower corners and presses on any crack or porous area in the concrete. That is why the wall and the base are waterproofed together, not separately.
It depends on the condition of the tank and the type of surface. Epoxy forms a smooth, fully sealed film that resists moisture, and it works well when the surface is level and ready to bond. A cementitious coat bonds deep into the concrete and suits rough surfaces or those that need levelling first. We decide which is right after inspecting the tank.
Yes, emptying is a basic requirement. No surface can be prepared and no lining applied on a wet wall or under water. The tank is fully emptied and cleaned until the surface is dry and ready to receive the waterproofing material. Tell us the size and location of the tank and we will work out the details with you.
Tell us the type of tank, ground or overhead, whether it is concrete or fibreglass, where the leak sign appears and whether the water level has dropped or damp shows on the outer wall. The clearer your description, the more directly we can point you to the right service.
Damp around the tank signals a leak from the tank walls, base or joints. The leak may be slow and invisible, but moisture builds up on the wall. The initial inspection pinpoints exactly where the leak comes from.
Tell them where the tank is (on the roof or underground), whether water drips from it or damp shows around its walls, whether the problem is recent or long-standing, and send photos of the tank and its surrounding walls on WhatsApp if you can.
