What is specific about Tabarjal for bathroom waterproofing

The centre of Tabarjal sits about 548 m above sea level (SRTM open elevation data). Team note on Tabarjal: 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..

Tabarjal sits about 548 m above sea level (SRTM open elevation data), and that height shapes where a bathroom waterproofing check begins. Before any materials are discussed, the technician first looks at the floor-to-wall junctions, the shower tray edge, and the area around drains and pipe penetrations, since these are the points where water most often finds a way through. Bathroom waterproofing in this kind of setting is usually priced per square metre, in a range of SAR 15–40 per m², so the surface area measured on the first visit is the figure that matters most to the quote. Spray foam (SAR 20–45 per m²) and epoxy coating (SAR 35–90 per m²) are the options most often compared for wet rooms, and the first check is which surfaces will actually be treated with them.

Some things can only be settled at the site visit. The technician will examine the substrate for hairline cracks, check whether old tiles are lifting, and test how the existing floor falls toward the drain. Where a crack is found, crack injection is priced per metre at SAR 40–120 per m, so the length of any crack can only be measured on site. The condition of the wall tiles, the grout lines, and any previous sealant also decides whether the old layers must come off. Nothing about these conditions should be assumed from a phone call or photographs alone, because the visit is where the real state of the room is confirmed.

To help the technician prepare, residents should note which bathroom has leaks or damp patches, when the problem first appeared, and whether the bathroom sits above a living space or a store. It helps to say whether the bathroom has a separate water tank nearby, since tank internal coating (SAR 25–60 per m²) is a different job and should be identified early. Please mention if a roof above the bathroom is flat, since liquid roof waterproofing (SAR 8–25 per m²) and bitumen membrane (SAR 15–35 per m²) would then be relevant. Finally, record the approximate room size and any access limits, such as a narrow stairwell or a shared building entrance, so the visit can be planned properly.

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