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 Ahsa
Underground tanks in a city like Al Ahsa face pressure from damp soil outside and water inside, and both cause concrete to crack. Soil in Al Ahsa often contains salts and groundwater is near the surface, so damp seepage and decay are common risks. Waterproofing begins with a thorough check of the base and inner and outer walls, then cleaning them and removing salts and damp, followed by treatment with bitumen, epoxy and foam based on the tank's condition. The first check shows the extent of damage and where water is leaking.
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 and groundwater in Al Ahsa soil speed up damage to concrete and joints at the tank base and walls.

Questions about Ground tank waterproofing in Al Ahsa
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 patches around the tank from outside, notice the water level dropping faster than usual, or smell mustiness near the tank, these signs point to a leak that needs checking.
Describe the tank location and rough size, mention whether you see damp or water leaking, and send a photo of the area around the tank on WhatsApp if you can to help with the first check.
