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-Hofuf
In a city like Al-Hofuf, most homes have concrete tanks in the basement or on the roof. Water carries salts from the ground and the salty groundwater of Al-Ahsa, so tank walls absorb them and pass them into interior walls and floors. Before the cementitious coat is applied, the tank is cleaned and checked for surface integrity, and any cracks or leaks are treated. The cementitious layer bonds into the concrete and forms a barrier that stops moisture and salts from passing through.
Al-Hofuf is a city in Al-Ahsa governorate in the Eastern Province, close to Al Shagaibiyah District, Historical Center Hafuf District and As Salhiyah District.
Concrete tank walls absorb water and salts easily because cement is porous, and the first inspection reveals whether there is damp or cracking.

Questions about Cementitious tank waterproofing in Al-Hofuf
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.
Concrete tank walls are porous and absorb water and salts from the ground, then transmit them to adjacent walls and floors. Sealing the tank with a cementitious coat stops this absorption and protects the structure from moisture and salts.
The tank is cleaned of debris and old residues, and inspected to confirm the walls are free of deep cracks or active leaks. Any existing cracks or leaks must be treated before the cementitious coat is applied to a sound, dry surface.
