Why water tank waterproofing differs in Tabuk

Team note on Tabuk: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins.. The centre of Tabuk sits about 762 m above sea level (SRTM open elevation data).

Water tank waterproofing in Tabuk: when to call a technician

The most common problem with water tanks in this service is slow seepage through hairline cracks and worn internal coatings, often noticed first as damp patches on the outside walls or a faint taste or colour change in the stored water. Tank internal coating is typically priced at SAR 25–55 per m², and crack injection at SAR 40–115 per metre, so a small repair is far cheaper when caught early than a full recoating later. If you see wet rings on the tank base, a persistent drop in water level without visible leaks, or flaking material inside the tank, it is time to book a technician.

Local conditions shape how the work is done. The centre of Tabuk sits about 762 m above sea level (SRTM open elevation data), which means the city is a highland area where temperature swings between day and night can stress tank surfaces and widen existing cracks over time. A technician will usually inspect the tank for movement at the joints as well as surface damage, and will check whether the tank sits on a level base. Where a tank is exposed to sun on the roof, liquid roof waterproofing at SAR 10–25 per m² or a bitumen membrane at SAR 15–35 per m² may be recommended to protect the structure beneath. Spray foam, priced at SAR 25–35 per m², is another option the technician may discuss for roof areas, depending on the access and the condition of the surface.

Before the visit, ask the technician to explain exactly which areas they will inspect and which materials they propose, and request a written quote that separates each item, such as internal coating, crack injection and any roof work. Ask how long the tank must be drained and how long it will take before it can be refilled safely, and confirm who will clean the tank before coating begins. It also helps to ask whether the price covers surface preparation, since poor preparation is a common cause of early failure. Finally, ask what warranty or follow-up inspection, if any, is included, so you know what to expect after the work is finished.

Some signs can be watched for a few days; others need a technician straight away — the signs list above helps you decide.

Signs worth paying attention to

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

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

The most common causes

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

Tools and methods, and when we use them

From the first visit to the report

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.
