Water Tank Insulation in Riyadh — Stopping Seepage and Protecting Ground and Roof Tanks
We insulate and waterproof underground concrete tanks and roof tanks in Riyadh to stop seepage, protect the structure around the tank and keep the stored water clean. Every job starts with draining and inspecting the tank, so the treatment matches the actual condition of the walls and joints.
Only need the tank cleaned? See water tank cleaning. Not sure where the water is going? Start with leak detection.
Signs your tank needs insulation
- The tank level drops overnight even when no one is using water.
- Damp patches, peeling paint or salt marks on walls or floors near the ground tank.
- Visible cracks, crumbling plaster or exposed steel inside a concrete tank.
- Rust-coloured or sandy water after the tank has been cleaned.
- A water bill that keeps rising without a visible leak inside the house.
- An old tank that was never coated, or a coating that is blistering and peeling.
What our tank insulation work covers
The right treatment depends on the tank material, its age and where the water is escaping. These are the steps we use most often in Riyadh villas and buildings.
Draining and inspection
We empty the tank and inspect walls, floor, corners, pipe entries and the manhole to find where water is getting out.
Surface preparation
Loose plaster and old failed coating are removed and the surface is cleaned and dried so the new layer bonds properly.
Crack and joint repair
Cracks, corners and pipe penetrations are repaired and sealed first, because most seepage starts at these weak points.
Internal coating
A waterproof internal coating suitable for drinking-water tanks is applied in the layers the product requires.
Curing and testing
The coating is left to cure for the period the manufacturer specifies, then the tank is filled and the level is watched.
Cover and connections
We check the manhole cover, float valve, overflow and pump connections so the tank stays sealed and clean.
How a tank insulation job works
Inspection visit
We drain or lower the tank, inspect it and explain the cause of the seepage and the treatment we recommend.
Quotation and timing
You get a clear price and the number of days the tank will be out of use, including curing time.
Repair and coating
Surface preparation, crack repair and the internal coating are carried out in order.
Cleaning, filling and follow-up
After curing, the tank is cleaned, filled and the water level is checked to confirm the seepage has stopped.
What affects the price of tank insulation
Tank insulation is priced after inspection, because two tanks of the same size can need very different work. The main factors are:
- Tank size and type — concrete ground tank, roof tank, or a separate fibreglass or polyethylene tank.
- The condition of the walls: hairline cracks need far less work than crumbling plaster or exposed steel.
- Whether old coating has to be stripped before the new one is applied.
- The coating system chosen and the number of layers it needs.
- Access to the tank and how much water must be pumped out.
Why choose us for tank insulation
- We find the cause first — sometimes the loss is from a pipe or float valve, not the tank, and we tell you so.
- Plumbing connections around the tank are repaired by the same team.
- A written guarantee on the work and a tax invoice on request.
- We explain how long the tank will be out of use before work starts, so you can plan for water.

Water tank insulation questions
How do I know the tank is leaking and not the pipes?
Close the main valve and the tank outlet and watch the level for several hours. If it still drops, the tank itself is likely losing water. Our leak detection team can confirm this with proper equipment.
How long will the tank be out of use?
It depends on the repairs and the curing time of the coating. We give you the exact number of days in the quotation.
Is the coating safe for drinking water?
We use internal coatings intended for drinking-water tanks and follow the curing time before the tank is filled again.
Can a cracked concrete tank be repaired instead of rebuilt?
In most cases, yes. Cracks and weak joints are repaired and then coated. If the structure is too damaged, we tell you before quoting.
Do you clean the tank after insulation?
Yes. The tank is washed and cleaned after curing and before it is filled.
