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

The service in Al-Hofuf
Ground tanks in homes in Al-Hofuf carry soil weight from outside and water pressure from inside together, which increases cracks in walls and the base. Work starts by checking the tank inside and out to find leaks and cracks, then the inner surface and base are cleaned thoroughly. Waterproof layers are applied to the base and up the walls, and the work often includes treating the joints between the base and walls where pressure builds up.
Al-Hofuf is a city in Al-Ahsa governorate in the Eastern Province, close to Al Shagaibiyah District, Historical Center Hafuf District and As Salhiyah District.
The joint between the tank base and walls is the first point of leakage, because pressure concentrates there.

Questions about Ground tank waterproofing in Al-Hofuf
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.
Look for dampness around the tank outside or under the floor, falling water level without clear use, and damp smells from below ground. Call Al Raya if you notice any of these signs.
Tell them the home's approximate age, when you first suspected a leak, whether you have seen damp inside the house or around the tank outside, and which rooms are above the tank.
