Water tank waterproofing in Alula: emergency
In short: Water tank waterproofing (emergency) in Alula starts with the fill test with level monitoring, then the crack injection (polyurethane or epoxy), before anything is opened. The centre of Alula sits about 697 m above sea level (SRTM open elevation data). Published price: Tank internal coating (per m²), SAR 25–60 per m²; anything else is quoted after the inspection.
What is specific about Alula for water tank waterproofing
Main roads in or near Alula: King Abdullah Road. The centre of Alula sits about 697 m above sea level (SRTM open elevation data).
Water tank leaks in Alula are usually an emergency because a tank that has lost its seal can empty quickly, damage pumps and fittings, and leave a household without water in the heat. The most common problem we see with rooftop and ground-level tanks is failure at the joints and seams, where the lining has cracked or lifted, and water seeps out or into the surrounding structure. Before any work starts, the first step is to stop the loss as far as practical, isolate the tank, and document where the water is coming from. A proper assessment then decides whether the fix is a local crack injection or a full internal coating.
Alula sits at about 697 m above sea level, which means a higher, drier, more exposed setting than the coastal cities. Sun exposure on rooftop tanks is intense, and daily temperature swings cause the lining to expand and contract, which is why surface coatings on exposed tanks can split over time. For that reason we look closely at the tank's condition under sunlight and at how the cover and fittings are holding up, not just the visible leak. Typical pricing for the relevant work runs from SAR 25–60 per m² for tank internal coating, SAR 40–120 per metre for crack injection, and SAR 8–25 per m² for liquid roof waterproofing where the tank sits on a roof. These ranges help you understand the likely scope, but the final figure depends on the area and access on site.
Before the visit, ask the provider to confirm what they will inspect first and how they will make the tank safe to work in. Ask whether they will drain and clean the tank before coating, because a coating applied over damp or dirty surfaces will not bond. Ask which material they propose and why, and whether it suits a tank exposed to strong sun at this altitude. Request a written quote that separates the inspection, the repair and any cleaning, so you can compare like with like. Finally, ask how soon they can attend, since an emergency visit should begin with a clear plan and a realistic timeline for restoring a safe water supply.
If water is flowing, close the main valve first, then call or message with photos.
Signs that call for water tank waterproofing
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 — we check this before anything else.
- A common cause: construction joints.
Tools we use in Alula
| Method | What it helps with | Its role in Alula |
|---|---|---|
| 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 |
From the first visit to the report
- 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.
