Before we start: what we know about Unaizah

The centre of Unaizah sits about 667 m above sea level (SRTM open elevation data). Team note on Unaizah: 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..

Should a clinic in Unaizah wait for a leak before looking at its water tank? Most property owners here ask that question once they notice damp patches or a drop in water quality, but a tank is much easier to protect before it fails. Unaizah sits at roughly 667 m above sea level, and the tanks serving clinics need a coating that will hold up through the daily cycle of filling and draining. Tank internal coating is priced at SAR 25–55 per m², which gives an owner a clear starting point when comparing the cost of protection against the cost of repairs after a leak has spread.

Our inspection begins with a visual check of the tank walls, floor, and joints, followed by a look at any cracks or old coating that has started to lift. Where cracks are found, crack injection is priced at SAR 40–115 per metre, and the team records the length of each crack so the owner can see the scope before work starts. The surface is then assessed for the right system, whether epoxy coating at SAR 35–85 per m² or spray foam at SAR 20–45 per m², since each suits different wall conditions. The inspector also notes the condition of any roof-mounted tank and the surrounding structure, so that rainwater runoff and the tank base are included in the report rather than treated as separate jobs.

Before the visit, it helps to clear access to the tank and its surrounding area so the inspector can reach the walls, lid, and base without delay. Keep a record of when the tank was last cleaned or recoated, and note any leaks, damp patches, or changes in water colour or smell you have seen. If the clinic uses a basement or bathroom near the tank, mention those areas too, since basement waterproofing (SAR 50–145 per m²) and bathroom waterproofing (SAR 15–40 per m²) are often assessed together. Having these details ready lets the visit focus on the findings that matter, and gives the owner a clearer basis for deciding which work to schedule first.

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