Before we start: what we know about Ahad Rafida

Main roads in or near Ahad Rafida: King Khalid Road. The centre of Ahad Rafida sits about 2055 m above sea level (SRTM open elevation data).

Team note on Ahad Rafida: 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 an office block in Ahad Rafida wait for a leak before it looks at its water tanks? Most property owners ask this when a damp patch appears on a ceiling or a tank level drops faster than it should. The short answer is no. The centre of Ahad Rafida sits about 2055 m above sea level, a fact that matters for planning because the site's elevation shapes how rooftop and ground-level tanks are exposed to sun, temperature swings and wind. Rooftop water tanks in commercial complexes face the harshest conditions, so a sensible owner checks them before problems spread into the structure below.

Our inspection begins with a visual review of the tank's internal and external surfaces, looking for cracks, flaking coatings and signs of water staining at joints. The technician then checks the tank's base and walls for hairline cracks, which can be sealed by crack injection priced at SAR 40–120 per metre. Where the internal lining has failed, the usual remedy is tank internal coating, priced at SAR 25–60 per m². The roof above the tank is checked as well, since liquid roof waterproofing at SAR 8–25 per m² and bitumen membrane at SAR 15–35 per m² are often the source of leaks that reach the tank area. Each finding is recorded so the owner can compare options before any work is approved.

Before the visit, gather the tank's installation records, any previous repair invoices and a rough plan of the roof showing the tank location and access points. Clear the area around the tank and the roof hatch so the technician can work safely, and note when leaks or discolouration were first seen. If the building has a basement, mention it at booking, since basement waterproofing at SAR 50–150 per m² and XPS boards at SAR 12–30 per m² may be relevant to the same site. Having this information ready helps the inspection finish in one visit and gives the owner a clear basis for deciding what to repair first.

For offices and commercial complexes, work is scheduled to avoid disrupting staff and visitors.
