Water tank waterproofing in Taif: the local context

The centre of Taif sits about 1673 m above sea level (SRTM open elevation data). Team note on Taif: 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..

Water tank waterproofing in Taif begins with the altitude. The centre of Taif sits about 1673 m above sea level (SRTM open elevation data), so cooler nights and sharp day-to-night temperature swings are common. These swings make hairline cracks in concrete tanks more likely to open and close, so the first thing a technician checks is the tank shell for existing cracks, joints and any staining that shows where water is already escaping. Because the coating must bond to a sound surface, the technician also looks at whether the tank is dry enough to prime and whether old coatings are peeling or lifting.

Several points are left to the site visit, because they depend on what is physically found on the day. The technician measures the internal surface area to confirm the square metres involved, then decides whether a tank internal coating, an epoxy coating or a crack injection (priced per metre) is the right treatment for each section. The tank's access, the water it holds, the condition of its lid and whether it sits on a roof, a basement or open ground all change the method and the price range. Published rates such as tank internal coating at SAR 25–55 per m² and epoxy coating at SAR 35–85 per m² are starting points only; the final figure follows the measured areas and the findings.

Information that helps the technician prepares the job well. Tell the crew the tank's approximate size, its material, how long it has leaked and whether it is used for drinking water, since that affects the products chosen. Clear access to the tank and a brief note of any past repairs will speed up the inspection. Where the tank is on a roof, mention whether liquid roof waterproofing (SAR 10–25 per m²) or a bitumen membrane (SAR 15–35 per m²) was used before. Keeping the water level low on the visit day lets the surface be seen properly and makes the assessment more accurate.

Prices shown on this page come from our own published price list for the city; the final price is set after inspection.

Signs worth paying attention to

If you notice one of these signs in Taif, it is a good moment to talk to the team:

• 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

• Damaged old coating.
• Cracks in the walls or floor — we check this before anything else.
• A common cause: 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.
