Water tank waterproofing in Khamis Mushait starts with a problem that most owners do not see until it is too late: hairline cracks and joints in concrete or block tanks that let water seep out and let the structure weaken from the inside. Rooftop tanks are especially exposed, because they sit in full sun and their walls expand and contract with daily temperature swings. The usual fix is a tank internal coating, priced at SAR 25–55 per m², which seals the inner surface, while crack injection at SAR 40–115 per metre deals with the individual splits before the coating goes on.
The local setting changes the approach. The centre of Khamis Mushait sits about 1998 m above sea level, so the air is cooler and drier than on the coast, but the sun is still strong and the nights can be cold. That combination means the tank walls face sharp swings in temperature, which is why a flexible coating is usually preferred over a rigid one. A good installer will inspect the tank for cracks first, repair them, and then choose a coating that can move with the concrete. Where the tank sits on a roof, a liquid roof waterproofing layer at SAR 10–25 per m² may also be needed to protect the slab beneath it from the same stress.
Before the visit, ask a few clear questions. Ask whether the quote includes crack injection or only the coating, since the two are priced separately. Ask how the tank will be emptied and cleaned before work starts, and how long it must stay empty for the coating to cure. Ask what the surface preparation involves, because a coating applied over dust or loose concrete will fail quickly. Finally, ask for a written breakdown per square metre and per metre so you can compare the quote against the ranges above and see exactly what you are paying for.
Each job ends with a written report that carries a verification code you can check on our site.
Signs worth paying attention to
The following signs are worth checking before they grow:
- A tank that leaks after testing
- Deposits and flaking inside the tank
- Unusual colour or taste in the water
The most common causes
- Damaged old coating — we check this before anything else.
- Cracks in the walls or floor — we check this before anything else.
- A common cause: construction joints.
How we choose the tool in Khamis Mushait
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
| Fill test with level monitoring | Whether a tank coating holds after the work | Limits: takes time to monitor the level |
| Crack injection (polyurethane or epoxy) | Stopping active water through cracks | Limits: treats the crack, not the water source |
The steps in order
- Emptying and ventilation: The tank is emptied and ventilated before entry.
- Cleaning and preparation: Loose material is removed down to a sound surface.
- Crack treatment: Active cracks are treated first.
- Coating layers: A material intended for drinking-water tanks is applied.
- Disinfection and fill test: The tank is disinfected and the level is monitored after filling.

Questions from Khamis Mushait
Do I need thermal insulation in Khamis Mushait despite its moderate climate?
Yes, thermal insulation keeps the home warm in winter, reduces the need for heating, and limits the effect of day-to-night temperature fluctuations.
Do I need an engineer before starting renovation?
It is advisable when there are deep cracks, tilting, or sinking in the floors, because these signs may indicate a structural problem. In simple cases such as peeling paint or limited dampness, an inspection by a specialized contractor may be sufficient.
Is thermal insulation necessary in Khamis Mushait despite its moderate climate?
Yes, although the climate is relatively moderate, the city experiences hot summers and cold winters. Thermal insulation helps keep the home comfortable in both seasons and reduces energy consumption throughout the year.
