What ground tank waterproofing includes
- Checking the tank walls, base and cold joints for cracks and weak points
- Cleaning and preparing the internal surface before any treatment or material is applied
- Sealing fine cracks and the cold joint between the wall and the base before waterproofing
- Treating the internal walls with a lining that can carry the pressure of stored water
- Treating the base and the transition zone between wall and base as a single unit
- Assessing the external wall condition where damp soil pressure is a factor in the leak
How the work goes
- 1
Tell us what you notice
Call or message us on WhatsApp and tell us where the leak shows in the tank and whether you notice damp in the surrounding soil or a drop in the water level.
- 2
Inspecting the tank and walls
The job starts with checking the walls, the base and the cold joints for cracks and weak points before any lining is applied.
- 3
Preparing the surface
Surface preparation includes cleaning the walls and sealing cracks and any gap in the joints, because a lining is only as good as the surface it goes onto.
- 4
Applying the waterproofing
The walls and base are treated as one unit, with particular attention to the cold joint zone between the wall and the base as it is the area most exposed to leaks.
What makes this treatment reliable
- We treat the base and walls as one unit
- We seal cold joints before waterproofing
- We choose a material suited to soil pressure
- We take your request by phone call or WhatsApp message
- Reach us by call or WhatsApp
The service in As Sunaidah District
Ground tanks in homes in a district like As Sunaidah often suffer damp and leaks because the surrounding soil is wet and often carries salts. Waterproofing starts at the tank base, corners and joints between walls, where water builds up under pressure. Surfaces are cleaned first and cracks are filled, then a waterproof layer of epoxy or bitumen is applied inside and out. The first inspection decides how much damp and salt are present and where the leak is, and this determines the material and treatment.
As Sunaidah District is a residential district in Al-Ahsa governorate in the Eastern Province, close to Munifah District, Ar Rafiah District and Al Marbidia District.
The tank base and corners are the weakest points, because water and pressure concentrate there more than anywhere else.

Questions about Ground tank waterproofing in As Sunaidah District
A ground tank carries the pressure of damp soil on its outer walls, which an overhead tank does not. So the walls need a treatment that can handle that additional pressure, and the cold joint between the wall and the base is more prone to cracking under these conditions.
The base receives the pressure of the stored water from above and that of damp or groundwater from below. The cold joint between the base pour and the wall pour is usually the first place a leak appears, because that joint is weaker than solid homogeneous concrete.
An internal lining protects water from escaping and treats the wall surface from inside. But if damp soil pressure is pushing water from outside in, the wall may also need external treatment. What suits each tank depends on the actual condition and position of the leak.
A fine crack in concrete does not let water through freely at first, but it widens with repeated filling and emptying as the concrete expands and contracts. When the crack reaches enough depth it becomes a direct path for water. That is why cracks are treated before the waterproofing layer, not after.
Tell us whether the tank is fully buried, partly buried or at ground level, where the leak shows such as the walls, the base or the cold joint between them, and whether you notice damp in the surrounding soil or a drop in the water level inside. These details help us identify the right treatment.
If you see damp on the inner or outer walls, smell mould, or the water level drops quickly, these are signs of a leak. Al Raya uses instruments to pinpoint exactly where the leak is.
Tell them the tank's approximate depth and size, when it was built, whether there is a current leak or damp, and whether the soil around the house is wet during rainy periods. Send photos of the tank or any damp patches on WhatsApp.
