Before we start: what we know about Yanbu

Team note on Yanbu: 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.. Main roads in or near Yanbu: King Abdulaziz Road, Umluj Road, Al Hanan Street.

The centre of Yanbu sits about 6 m above sea level (SRTM open elevation data). Yanbu is about 1.2 km from the sea coast (OpenStreetMap).

Will a basement in Yanbu really need waterproofing if the city is near the coast? The short answer is that location matters here. The centre of Yanbu sits about 6 m above sea level, and the city is about 1.2 km from the sea coast. Those two facts mean that ground conditions and moisture can differ from one plot to the next, so a basement or foundation should be assessed on its own merits rather than assumed to be safe or at risk. For basement waterproofing, the published range is SAR 50–150 per m², and crack injection, where a crack needs sealing, is priced at SAR 40–120 per metre.

A visit usually starts with a walk through the basement or foundation area to look for damp patches, staining, efflorescence, and visible cracks. The inspector will note where water appears to enter, how far the damp extends up the walls, and whether any cracks are active or only cosmetic. Measurements of the affected area are taken so the surface can be quoted per square metre, and crack lengths are recorded in metres. Where the problem is connected to a roof, bathroom, or water tank, those areas are checked too, since the same unit rates apply to bathroom waterproofing (SAR 15–40 per m²), epoxy coating (SAR 35–90 per m²), and tank internal coating (SAR 25–60 per m²). The aim is to find the source of moisture rather than only treat the surface.

Before the visit, it helps to clear the area around the basement walls and any storage near the affected surfaces so the inspector can see the full extent of the damp. Gather any previous repair records, invoices, or notes about earlier leaks, as they show where water has been before. Note when you first saw the moisture and whether it worsens after rain or when the sprinklers run. Measure the basement roughly so you have the area in square metres ready, and mark any cracks you have noticed. Having this information ready lets the visit focus on the fixes that matter and makes it easier to compare the published rates for each option.
