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 Al Jishshah
In a district like Al Jishshah, most homes have concrete tanks underground or on the ground floor. Groundwater in Al-Ahsa carries high levels of salt, and concrete tank walls absorb these salts and moisture, passing them to house walls and foundations. The tank is first cleaned and inspected for cracks and weakness, then weak points are treated. The cementitious coat is then applied, bonding with the concrete to form a barrier against moisture and salts.
Al Jishshah is a district in Al-Ahsa governorate in the Eastern Province, close to Al Markaz, Al Jafr and As Sabat.
The salty groundwater of Al-Ahsa makes moisture and salt absorption from tanks into walls a common issue, and the first inspection reveals the extent of damage.

Questions about Cementitious tank waterproofing in Al Jishshah
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.
Signs of seepage include white marks or discolouration on interior walls near the tank, damp on the floor, or a musty smell. These show that moisture and salts are passing through the concrete tank walls.
State the tank location (below ground or ground floor), whether you see white marks on adjacent walls, if the floor is damp, and roughly how old the house is. Send photos of the tank and affected walls on WhatsApp if you can.
