We inspect the roof and the tank together
We check the condition of the roof slab, the joints, the edges and the parapet, then the tank base and its outer walls, because each affects the other.
- 3
We waterproof the roof first
The roof slab is prepared and the cracks, joints and drains are treated, then the waterproofing layer is applied across the full area including the zone around the tank base.
- 4
We treat the tank on a finished roof
Once the roof is ready we waterproof the tank base and its outer walls, so both layers work together and neither undoes what the other seals.
One treatment instead of two
- The tank and the roof are treated together in one complete job
- The order of the work stops one waterproofing layer from damaging the other
- We waterproof and thermally insulate according to each surface's condition
- We take your request by phone call or WhatsApp message
- Cost depends on the case, message us to work it out together
The service in UmmTali
In a village like UmmTali, the water tank sits on the flat roof, directly above a room or ceiling exposed to damp and heat. If the tank leaks, water soaks the roof and walls, and if you insulate only the roof, the tank keeps dripping and ruins the work. The team checks the tank position, the joints around it and cracks in the tank walls, then seals the tank inside and out, and insulates the roof around it with layers of foam, bitumen and epoxy. The first inspection shows whether water is leaking from the tank walls, the base, or the connections.
UmmTali is a village in Al-Ahsa governorate in the Eastern Province, close to 'Uray'irah, Umm al Hamam and Umm Rubay'ah.
The joint between the tank wall and the roof is where water enters first, so it needs tight waterproofing.

Questions about Tanks & roofs together in UmmTali
Yes, if the roof slab is sound and the joints and drains are tight, treating the tank alone is enough. But if the roof has cracks or signs of damp, ignoring it means water will find a way through even after the tank is sealed. That is why we check both before deciding.
They suit the roof's condition and what it needs. Bitumen rolls are laid over open areas and the edges and joints are sealed. Epoxy suits the finish around the tank base and at the drains. Polyurethane foam may be added for thermal insulation where the roof is exposed to direct sun.
The tank base sits directly on the roof slab, and any water that leaks from under the tank stops only where the waterproofing ends. If the slab is bare or has an old worn layer, the water soaks into it and reaches the floor below. Over time the slab itself cracks under the accumulated moisture.
If the stain is concentrated directly below the tank, the tank is likely the cause. If it spreads across a wider area of the ceiling, the roof is the more likely source. But the two often work together to bring water to the same place, so inspection alone tells them apart with certainty.
Tell us whether the damp appears on the top-floor ceiling, on the roof surface around the tank, or both. Tell us whether the tank is concrete or fibreglass and whether water appears under its base. These details tell us where to start and which materials suit the situation.
If you see water directly under the tank in the room below, the leak is from the tank or its pipes. If damp appears away from the tank, the problem is in the roof itself. The team inspects both.
Yes, because a leak from the tank ruins roof sealing, and water seeping from the roof wets the tank. Treating one without the other means the job will have to be redone.
