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).

Picture the owner of a small hotel or serviced apartment block in Alula. Guests arrive expecting clean, reliable water, and the owner relies on a rooftop or ground-level water tank to keep taps and showers running through busy seasons. When a tank starts to leak or stains appear on the walls of the plant room, the problem quickly becomes a guest complaint, a cleaning headache and a repair bill that grows the longer it is ignored.

The centre of Alula sits about 697 m above sea level, which matters for a property owner. Sitting at this elevation in a desert setting means sun exposure is intense, and daily temperature swings can stress coatings and joints on exposed tanks and roofs. Owners should expect that materials which perform well in cooler coastal cities may need closer inspection here. Tank internal coating is priced at SAR 25–60 per m², so a planned recoating is usually far cheaper than emergency repairs after leaks have already damaged the tank base. Liquid roof waterproofing at SAR 8–25 per m² and bitumen membrane at SAR 15–35 per m² offer options for the roof that feeds or shelters the tank, and crack injection at SAR 40–120 per metre can seal hairline cracks before they widen.

A sensible sequence starts with a full walk-around. Inspect the tank interior for flaking, staining and cracks, and check the roof and any basement wall that sits against the tank. Next, mark every crack and note its length, since crack injection is priced per metre. Clean and dry the surfaces thoroughly before any coating is applied, because moisture trapped under a membrane is a common cause of failure. Then choose the system that fits each area: tank internal coating for the water side, liquid or bitumen systems for the roof, and XPS boards at SAR 12–30 per m² where insulation is needed around a tank. Finally, schedule the work outside peak occupancy, keep a written record of the areas treated, and set a reminder to re-inspect the tank each year so small issues are caught early.

For hotels and serviced apartments, rooms are handled in batches to keep units available.

Signs that call for water tank waterproofing

These are the signs most often linked to water tank waterproofing:

• Unusual colour or taste in the water
• Deposits and flaking inside the tank
• A tank that leaks after testing

The most common causes

• Construction joints.
• Cracks in the walls or floor — we check this before anything else.
• Damaged old coating.

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.
