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 UmmTali
Ground tanks in a village like UmmTali are often directly under the house, with water pressing inward on the walls and floor, while damp and salty soil presses from outside, especially in an area like Al-Ahsa where groundwater is high. Treatment starts by cleaning the floor and walls and removing any salt or corrosion, then waterproofing is applied inside using materials that withstand pressure. The tank is inspected first to find cracks and weak points in the walls and floor.
UmmTali is a village in Al-Ahsa governorate in the Eastern Province, close to 'Uray'irah, Umm al Hamam and Umm Rubay'ah.
The tank floor is checked first, because the weight of water and soil pressure make leaks there most likely.

Questions about Ground tank waterproofing in UmmTali
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 in the soil around the tank or in nearby walls, or if water level drops with no clear use, the tank is leaking. Tap the tank walls from inside with metal if you can; a hollow sound means there is a void that needs treatment.
Tell them where the tank is, under the house or in the yard, and roughly when the house was built, whether there is already a leak or damp stain and where, and send photos of wet patches if you see them.
