Before we start: what we know about Tabuk

The centre of Tabuk sits about 762 m above sea level (SRTM open elevation data). Team note on Tabuk: 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..

Is a leaking bathroom in a Tabuk apartment worth fixing now, or can it wait until the next renovation? Tabuk sits about 762 m above sea level, and that matters less for the leak itself than for the planning around it: a wet bathroom floor, a damp wall behind the tiles, or a stain on the ceiling below usually means the sealing layer under the tiles has failed, and it tends to get worse rather than better. Bathroom waterproofing for apartments here is typically priced at SAR 15–40 per m², which makes early repair a modest step compared with damage to the flat below or to the structure behind the walls.

The inspection starts with a visual check of the floor, the junction between floor and wall, the shower area and the edges around the drain. The technician looks for hairline cracks, lifted tiles, softened grout and discolouration on the adjoining wall or ceiling. Where cracks are present, crack injection is priced at SAR 40–115 per metre, so the inspector measures the length of each crack rather than estimating it. For the floor and wall surfaces, the options include epoxy coating at SAR 35–85 per m², spray foam at SAR 20–45 per m², and bitumen membrane at SAR 15–35 per m², and the inspector recommends one based on what is visible and how the surface behaves under water. Where a water tank sits nearby or on the roof, tank internal coating at SAR 25–55 per m² and liquid roof waterproofing at SAR 10–25 per m² may also be relevant to the same leak path, so the inspector checks those points too.

Before the visit, clear the bathroom floor and the area around the shower so the surfaces can be examined directly. Note when the leak appears, whether after showering, after rain, or on its own, because that timing helps narrow down the source. Take photographs of any stains on the ceiling or walls in the flat below, and keep them handy if that unit is affected. Have the approximate floor area of the bathroom ready in square metres, since every price on this page is calculated per m². Finally, if any old tiles are loose, mark them with tape so the technician can find them quickly on arrival.

In apartment buildings, the floor below is often where a leak shows first.
