Before we start: what we know about Baish

The centre of Baish sits about 84 m above sea level (SRTM open elevation data). Team note on Baish: 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..

Bathroom waterproofing for villas in Baish starts with the ground the house sits on. The centre of Baish sits about 84 m above sea level (SRTM open elevation data), so the technician first checks how water moves across and under the plot rather than assuming it pools. Because the bathroom sits above the structure, the first things looked at are the floor falls toward the drain, the join between wall and floor, and any hairline cracks that could carry moisture into the walls below. A fixed bathroom waterproofing rate is typically quoted at SAR 15–40 per m², but the final figure depends on what is found once the surfaces are opened up.

Several decisions are left to the site visit, because they cannot be judged from a plan. The technician will confirm whether the existing floor is sound enough to take a coating, how much preparation the surface needs, and whether a cracked joint needs crack injection at SAR 40–120 per metre instead of a simple surface seal. The choice between epoxy coating at SAR 35–90 per m², spray foam at SAR 20–45 per m², or a bitumen membrane at SAR 15–35 per m² also depends on the substrate, the amount of wet use, and how the room is laid out. Where the bathroom is above a rooftop or terrace, liquid roof waterproofing at SAR 8–25 per m² may be considered for the adjoining area. Any work that reaches a water tank or a basement is priced separately, for example tank internal coating at SAR 25–60 per m², and basement waterproofing at SAR 50–150 per m².

To help the technician arrive prepared, the homeowner should note the age of the villa, any past leaks or damp patches, and whether the bathroom has been tiled over before. Share photographs of the floor, the drain, and the wall junctions, and say where the water usually appears. Mention if insulation boards such as XPS (SAR 12–30 per m²) have ever been used in the surrounding structure, and confirm access to the room below. With this information, the visit can focus on the real problem and the quote can reflect the actual work needed.

In a villa, tanks, the roof and the yard lines are usually yours to look after, so it helps to know where the main valve and tank hatches are.
