Before we start: what we know about Alqunfudhah

Team note on Alqunfudhah: 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.. Alqunfudhah is about 0.4 km from the sea coast (OpenStreetMap).

The centre of Alqunfudhah sits about 7 m above sea level (SRTM open elevation data).

Start with the location, because it shapes what a technician checks first in a villa bathroom in Alqunfudhah. The centre of the town sits about 7 m above sea level, according to SRTM open elevation data, and the town is about 0.4 km from the sea coast, based on OpenStreetMap. Those two facts mean the air near the floor and the salt-laden moisture that can reach ground-level walls are real considerations, so the first checks cover the floor junction, the wall base and the shower area, where water tends to sit and move. Crack lines at tile joints and around drains are examined before any product is chosen, because a small crack can carry water into a wall that looks dry from the inside.

What is left to the site visit is the detail that a general description cannot settle. The technician confirms whether the existing surface is solid, damp, or lifting, whether there is any sign of rising moisture behind a finished wall, and how the drain and the floor fall are laid out. Crack injection is priced per metre, while coatings are priced per square metre, so the measured length of cracks and the exact floor and wall area are only known on site. The choice between a liquid membrane, an epoxy coating, a spray foam or a bitumen system is also made there, based on how the room is used and what the surface can take. Where a room sits over a utility space or a tank, that is noted at the visit too, since it changes the scope.

To help the technician, it is useful to have the bathroom dimensions ready, a note of any past leaks, and details of the finish already in place, such as tiles, screed or render. Photos of cracks, staining and the drain area save time on the first visit. Ask whether the room has a separate shower tray, because the waterproofing extent depends on it. Indicative rates for bathroom waterproofing run from SAR 15 to SAR 40 per m², with epoxy coating at SAR 35 to SAR 90 per m² and spray foam at SAR 20 to SAR 45 per m², but the final quote follows the measured area and the system chosen on site.

Villas often have several lines and tanks; we test them one at a time so the cause is clear.

Signs worth paying attention to
