What cementitious tank waterproofing includes
- Checking the concrete tank walls to find cracks, pores and leak points
- Cleaning the inner surface of dust, algae and residue from old coatings
- Roughening the surface so the cementitious coat grips the concrete wall firmly
- Treating fine cracks and structural joints before the waterproofing coat is applied
- Applying the cementitious coat to the dampened wall with care at corners and edges
- Reviewing the surfaces after application to confirm the coat covers the full wall area
From your call to a sealed wall
- 1
Tell us about your tank
Call or message us on WhatsApp, and describe the tank size, its location and what you notice: any damp or cracks in the walls.
- 2
Preparing the concrete surface
The walls are cleaned of dust, algae and old coating residue, then the surface is roughened so it takes the cementitious coat well.
- 3
Treating cracks and joints
Fine cracks and structural joints are treated first, because the waterproofing coat alone cannot close an existing crack.
- 4
Applying the cementitious coat
The cementitious material is applied to the prepared and dampened wall so it absorbs into it, and is worked again over edges and corners for full contact.
Concrete and cement work together
- The coat bonds with the concrete tank wall
- Works on damp walls that are hard to dry fully
- Seals pores and penetrates the concrete from within
- We treat cracks and joints before the coat goes on
- We take your request by phone call or WhatsApp message
The service in King Faisal University 3rd
In an area like King Faisal University 3rd, concrete tanks serve residential buildings and villas, operating under constant pressure. Water inside the tank presses on the concrete walls, and intense heat and weather cause fine cracks. In Al-Ahsa, where soil and groundwater are salty, minerals seep through walls and deposit in the concrete, weakening it over time. The cementitious coating penetrates concrete pores and seals them from within, so water cannot pass through. The tank is inspected inside and out first, and walls cleaned of any dirt or deposits before starting.
King Faisal University 3rd is a residential area in Al-Ahsa governorate in the Eastern Province, close to Hajr District, Sports City and Mansubi Al Taleem 1st District.
Constant water pressure inside the tank seeks the weakest point in the walls, so small cracks become pathways for seepage.

Questions about Cementitious tank waterproofing in King Faisal University 3rd
The cementitious material needs moisture in the surface to absorb into it and bond with it rather than drying out on top. If applied to a fully dry wall in the heat, the coat dries before it can penetrate the concrete and the result is weaker.
Yes, cementitious waterproofing systems are designed to resist water pressure from both sides, inside and outside. That is the main difference between a true waterproofing material and a plain cement paint. The surface must be clean and free of old coatings that block bonding.
It depends on the state of the old lining. If it is sound and not peeling it may be assessed for keeping, but if it is loose or flaking it must be removed first, because the cementitious coat needs direct contact with the concrete, not with a failing old lining.
The tank must be emptied, cleaned and prepared before waterproofing in any case. The main advantage of a cementitious material is that it works with damp concrete and does not require the complete dryness that some resin-based materials need.
Tell us whether the tank is a ground tank or an overhead tank, what you can see such as seepage in the wall, damp at the base or a peeling old coat, and whether the tank is currently in use or empty. This helps us assess what the surface needs before the cementitious coat.
If an old tank is structurally sound but leaking, cementitious coating may successfully stop the seepage. But if there is significant damage, we may need further assessment after inspection.
Tell us the tank size, whether it is on the roof or underground, and if there is visible leakage now or damp patches. Send photos from outside and inside if possible on WhatsApp.
