What is specific about Aldiriyah for water tank waterproofing

The centre of Aldiriyah sits about 655 m above sea level (SRTM open elevation data). Team note on Aldiriyah: 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 for rest houses and farms in Aldiriyah starts with a problem that most owners notice too late: a tank that looks sound from the outside but lets water seep through its walls and floor. On rest houses and farms, tanks are often left partly empty for long stretches and then refilled, which lets cracks open and close with changing temperatures. Leaks in these tanks are usually traced to hairline cracks at the joints and corners, and to old coatings that have peeled away from the concrete. Left alone, the damage spreads into the surrounding walls and can lead to contaminated stored water.

Aldiriyah sits about 655 m above sea level, which shapes how we approach the job. At this altitude the local climate brings wide swings between hot days and cooler nights, so the concrete moves more and cracks form more readily. For that reason we normally start with crack injection, which costs SAR 40–120 per metre, before any surface coating goes on. Internal tank coating, priced at SAR 25–60 per m², is then applied to seal the whole interior. Where a tank sits in or beside a basement, the same logic applies to basement waterproofing at SAR 50–150 per m², and roof areas above the tank can be treated with liquid roof waterproofing at SAR 8–25 per m² to stop water entering from above.

Before a visit, ask the provider a few direct questions. Ask whether they will inspect and record the existing cracks before quoting, and whether the quote separates crack injection from the coating itself. Ask which products they propose and how the tank will be prepared, since an unprepared surface will not hold any coating well. Check that the price is given per square metre or per metre of crack, so you can compare it with the ranges above. Finally, ask how long the tank must stay empty during the work and how it will be tested before it is refilled. Clear answers to these points will tell you whether the provider understands the conditions at your property.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

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 — we check this before anything else.
• Construction joints — we check this before anything else.

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.
