Team note on Alzulfi: 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..

Does a clinic water tank in Alzulfi really need waterproofing, given how dry the air can feel at the top of the Hijaz? The short answer is yes. The centre of Alzulfi sits about 615 m above sea level (SRTM open elevation data), and that height does not protect a tank from leaks, cracks, or seepage. Clinics depend on a steady supply for hand washing, sterilisation, and patient rooms, so a failing tank can disrupt care quickly. Tank internal coating is priced at SAR 25–60 per m², and crack injection at SAR 40–120 per metre, so the cost of a proper check is usually small compared with the disruption of an emergency repair.

When we inspect a clinic tank, we start by looking at the interior surfaces for hairline cracks, flaking old coatings, and any staining that shows water has been moving through the walls. We then check the joints and the points where pipes enter and leave, since these are the most common routes for leaks. Where the tank sits on or beside a basement or service area, we also look at how the outer walls meet the ground. Based on what we find, we recommend a suitable system. An epoxy coating (SAR 35–90 per m²) is often used on interior surfaces, while spray foam (SAR 20–45 per m²) or a bitumen membrane (SAR 15–35 per m²) may suit other sections. Every recommendation is explained before any work begins so the clinic can decide with full information.

Before the visit, please make sure the tank area is accessible and that the clinic's supply schedule is known, so we can plan around patient hours. Note any leaks, damp patches, or changes in water pressure you have already seen, and keep any previous repair records or maintenance notes. If the tank is on the roof, let us know whether the roof is also used for equipment, as this affects the roof options such as liquid roof waterproofing (SAR 8–25 per m²). Clear information at the start shortens the inspection and helps us give you a quote that matches the real condition of your tank.

For clinics, work is scheduled around patient hours and kept to the areas that need it.

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

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