Bathroom waterproofing in Al Yrmwk, Riyadh, starts with a close look at what is already in place, because the work should not break anything that is still sound. The area sits at the centre point 24.8085, 46.7835, about 15.2 km from the centre of Riyadh, with an approximate radius of 3.2 km. Its centre lies about 598 m above sea level, which is a useful reminder that the climate and building conditions here differ from those of lower coastal cities. Before any product is chosen, the technician looks at the floor, the wall junctions and the drain, since these are the points where water most often finds its way through.

Some things can only be settled at the site visit. The technician will check whether the existing surface is cracked, and if so, whether the crack needs injection, which is priced at SAR 40–125 per metre. They will decide between a liquid membrane, a spray foam or an epoxy coating, using the bathroom rate of SAR 15–40 per m² as the starting reference and the wider product ranges, such as epoxy coating at SAR 35–95 per m² or spray foam at SAR 20–45 per m², as the guide for the final choice. The size of the room, the number of floor drains and the condition of the tiles are also judged on the day. No single figure can be fixed until these points are seen in person.

To help the technician, it is useful to have a few details ready. Note the bathroom's approximate floor area in square metres and the length of any visible cracks in metres. Say whether the bathroom sits above another living space, since this affects how carefully the work must be sealed. Mention any past leaks, stains on the ceiling below, or areas where tiles have loosened. Clear access to the bathroom, and a plan of when water can be shut off, will also make the visit smoother. With this information in hand, the technician can plan the work so that the existing structure is protected throughout.

The aim is to locate the cause with instruments first, so any opening is limited to one point.
