Team note on Samtah: 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..

Samtah sits about 61 m above sea level, according to SRTM open elevation data, and it is about 22.6 km from the sea coast, as measured in OpenStreetMap. These two facts shape the first checks on any floor or balcony job here. Because the town is inland and reasonably elevated, the technician looks first at how water actually moves across the surface and where it collects, rather than assuming that coastal conditions apply. The check starts with the slope of the floor and the drainage outlets, then the balcony edges and the junction with the wall, since these are the points where water tends to pool and find a way in.

The following points are left to the site visit, because they cannot be judged from a distance. The technician needs to see the actual condition of the surface, whether there are cracks, hollow areas, or old failed coatings, and whether the substrate is sound enough to take a new layer. The choice of system depends on the area and the use. A balcony exposed to rain calls for a different approach from a bathroom floor or a basement slab. Typical rates for common systems include liquid roof waterproofing at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², spray foam at SAR 20–45 per m², and epoxy coating at SAR 35–90 per m². Crack injection is priced at SAR 40–120 per metre. The site visit confirms which of these fits, and the final quote follows from measured areas and lengths.

Information that helps the technician includes the exact location and approximate size of each floor or balcony, the age of the existing surface, any history of leaks or staining on the ceiling below, and whether the area is used for foot traffic, planters, or storage. If the work is in a bathroom, the technician will also note the expected range of SAR 15–40 per m², while a basement or tank job falls under separate ranges of SAR 50–150 per m² and SAR 25–60 per m² respectively. Clear photographs and access to the drainage points make the visit faster and the assessment more accurate.

Each job ends with a written report that carries a verification code you can check on our site.
