Before we start: what we know about Aldiriyah

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 in Aldiriyah starts with the basics of the site, and the first check is elevation. The centre of Aldiriyah sits about 655 m above sea level (SRTM open elevation data), so tanks here are often placed on rooftops or raised platforms where wind exposure and sun heat are part of the daily picture. Before any coating is discussed, the technician looks at where the tank stands, how the supporting slab is joined to the wall, and whether water has already left marks on the outside. Those signs tell us more about the likely route of leakage than the age of the tank alone.

Several things are deliberately left to the site visit. The actual condition of the concrete, the depth of any crack, and whether the inside surface can be cleaned enough to hold a new coat are all judged by eye and by touch once the tank is accessible. Pricing depends on the scope, so the technician measures the area on the day rather than guessing from a photo. Typical ranges for reference are tank internal coating at SAR 25–60 per m² and epoxy coating at SAR 35–90 per m², but the right product is chosen only after the surface is inspected. Crack injection, priced at SAR 40–120 per metre, is also measured in place.

To help the technician arrive prepared, it is useful to know when the tank was last drained and cleaned, whether the water supply is treated before storage, and whether any previous repair was done with a sealant that might not bond to the new layer. A note of how often the tank runs low or sits full for long periods is valuable, since that affects how the coating ages. Access details matter too: a clear route to the roof, a safe place to park equipment, and a time when the tank can stay empty for the work to proceed. With this information in hand, the visit moves quickly, and the finished job keeps the water inside the tank where it belongs.

The aim is to locate the cause with instruments first, so any opening is limited to one point.

Signs worth paying attention to

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

The most common causes

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

How we choose the tool in Aldiriyah

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.
