Water tank waterproofing in Alula: the local context

The centre of Alula sits about 697 m above sea level (SRTM open elevation data). Main roads in or near Alula: King Abdullah Road.

Picture a homeowner in Alula who keeps a rooftop or ground-level water tank for household use. Most days the tank simply sits there, filled from the municipal supply or a delivery truck, and it is easy to forget it until a damp patch appears on a ceiling or the water starts to taste odd. By then the leak has often been working for a while. Owners of villas and small apartment buildings tend to notice the problem only when the cost of repair has already grown, which is why a planned check is the sensible habit.

The local setting matters here. The centre of Alula sits about 697 m above sea level, and the surrounding terrain is rugged and dry. Heat builds up on exposed roofs and tank surfaces during the day, then temperatures drop at night. That daily swing can open small hairline cracks in concrete and in old coatings, and those cracks are the usual route for water to escape or for contaminants to enter. Because the area is arid, a tank that leaks quietly is easy to overlook, and the lost water is a real waste of a scarce resource. A periodic check helps catch these small faults before they spread.

A practical routine starts with an empty, clean tank and a dry day for inspection. First, look at the tank walls, floor and joints for cracks, flaking or soft patches, and mark anything suspicious. Second, check the roof area and the surfaces around the tank for ponding, blistering or failed sealant. Third, if you find cracks, get a quote for crack injection, which is priced at SAR 40–120 per metre, and for internal tank coating, priced at SAR 25–60 per m². Fourth, where a roof is exposed, compare liquid roof waterproofing at SAR 8–25 per m² with bitumen membrane at SAR 15–35 per m², and note that XPS boards at SAR 12–30 per m² can add insulation. Finally, record the date and findings, and repeat the check on a regular schedule so that small repairs remain small.

Preventive checks follow a written schedule instead of waiting for a fault.

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

Where the problem usually comes from

• A common cause: damaged old coating.
• Cracks in the walls or floor.
• Construction joints.

Tools and methods, and when we use them

How the work is done, step by step

1. Emptying and ventilation: The tank is emptied and ventilated before entry.
2. Cleaning and preparation: Loose material is removed down to a sound surface.
3. Crack treatment: Active cracks are treated first.
4. Coating layers: A material intended for drinking-water tanks is applied.
5. Disinfection and fill test: The tank is disinfected and the level is monitored after filling.
