When to book this service
Peeling or flaking coating
Flakes of old paint or coating in the water, or visible peeling during a clean, mean the lining has failed and needs to be redone.
Rough, porous concrete
Bare concrete that feels sandy holds biofilm and sediment, so the tank gets dirty faster after each clean.
Seepage or rust
Damp soil around an underground tank or rust inside an old metal tank point to a surface that no longer protects the water.
Water tank coating in Dubai is mainly a job for concrete underground tanks under older villas and small buildings, and for the occasional old metal tank. When the original lining has worn away, the bare concrete becomes rough and porous, collects sediment and biofilm, and can start to crack or let groundwater seep in. A new lining gives the water a smooth, sealed surface again.
When coating makes sense
The usual trigger is what the team finds during underground tank cleaning: peeling paint, sandy concrete, hairline cracks or damp patches. Coating is a bigger decision than cleaning, so a good company will show you photos and explain the options before quoting. For a tank that is structurally sound but worn on the surface, relining is often the practical choice instead of building a new tank.
How the work is done
The tank is emptied, cleaned and dried. Loose coating is removed and the surface is prepared so that the new lining bonds. Cracks and damaged concrete are repaired first. The lining, often an epoxy system, is applied in coats, and it must cure fully before the tank is refilled. The tank is then disinfected and filled. The whole process usually takes several days, which is why it is best planned rather than done in a hurry.
| Step | Why it matters |
|---|---|
| Drying the tank | Coatings do not bond to wet concrete |
| Crack repair | A lining over a moving crack fails early |
| Correct product | Only drinking-water-rated coatings |
| Full cure | Prevents taste and odour in the water |

Frequently asked questions
How much does water tank coating cost?
As an indication, relining a villa underground tank starts from AED 1,500. The price depends on the size, the condition of the concrete and the coating system, and is quoted after a survey.
How long is the tank out of use?
Usually several days, because the tank must be dry before coating and the coating needs time to cure. The company will tell you how to manage the water supply in the meantime.
Is epoxy safe for drinking water tanks?
Only coatings that are certified for contact with drinking water should be used. Ask the company for the product name and its certification before agreeing to the job.
Can a GRP roof tank be coated?
GRP tanks are not usually coated inside. A damaged GRP panel is repaired or replaced instead.
