Water tank waterproofing for residential buildings in Alula
In short: In Alula (Alula), water tank waterproofing for residential buildings begins with the fill test with level monitoring and the crack injection (polyurethane or epoxy); nothing is opened until the position is clear. The centre of Alula sits about 697 m above sea level (SRTM open elevation data). Pricing starts from Tank internal coating (per m²) (SAR 25–60 per m²), and other items are quoted after the visit.
Water tank waterproofing in Alula: the local context
Main roads in or near Alula: King Abdullah Road. The centre of Alula sits about 697 m above sea level (SRTM open elevation data).
Before any coating is chosen for a water tank in Alula, the first thing checked is the tank's interior condition and its exposure to the local climate. The centre of Alula sits about 697 m above sea level, so the tank is set in a town at real altitude, and that matters for how the site is read and how the surfaces are prepared. The technician looks for cracks, flaking, old coating that has lifted, and any sign of seepage at joints or at the base. Where the tank is internal and holds drinking water, the cost of the coating work usually falls in the range of SAR 25–60 per m², and the first check is whether the existing surface can take a new layer at all, because a poor base will undo any product applied over it.
Some things can only be settled on the site visit. The true area to be treated must be measured, since the price is quoted per square metre and the tank's shape, depth and access determine how much surface there is to cover. The technician also needs to see the state of the tank lid, the inlet and outlet pipes, and the points where walls meet the floor. Whether a crack needs injecting, which is priced per metre at SAR 40–120 per m, can only be judged once the crack is open to view. The choice between an epoxy finish at SAR 35–90 per m² and a lighter treatment is also left to the visit, after the surface has been seen and tested.
Information that helps the technician works best when it is gathered before the team arrives. It is useful to know when the tank was last cleaned or emptied, whether the water has been tested, and if there have been past leaks or repairs. Access to the tank, the depth of the water at the time of inspection and the position of the roof above it should all be known in advance. With this detail in hand, the technician can plan the work, estimate the area and explain the options clearly to the household, so the repair is matched to the tank rather than to a general guess.
For a residential building, shared risers, tanks and pumps are checked as one system.
Signs worth paying attention to
The following signs are worth checking before they grow:
- Deposits and flaking inside the tank
- A tank that leaks after testing
- Unusual colour or taste in the water
Where the problem usually comes from
- A common cause: cracks in the walls or floor.
- Damaged old coating.
- A common cause: construction joints.
Tools and methods, and when we use them
| 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 |
| Crack injection (polyurethane or epoxy) | Stopping active water through cracks | Limits: treats the crack, not the water source |
| Fill test with level monitoring | Whether a tank coating holds after the work | Limits: takes time to monitor the level |
How the work is done, step by step
- 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.
