Bathroom waterproofing in Khobar: the local context

Team note on Khobar: 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.. The centre of Khobar sits about 9 m above sea level (SRTM open elevation data).

Khobar is about 1.8 km from the sea coast (OpenStreetMap).

Does a company with several buildings in Khobar need to schedule bathroom waterproofing every time a leak appears? Here the answer depends on the site and the work, and an annual contract lets a property team plan it before problems spread. Khobar's centre sits about 9 m above sea level, and the city is about 1.8 km from the sea coast, so buildings here sit close to the coastal air and the damp that comes with it. For bathroom waterproofing, the rate is SAR 15–40 per m², which gives a company a clear basis to budget across a portfolio of washrooms rather than reacting to each complaint.

The visit to a bathroom starts with a check of the floor, walls and junctions where water is most likely to get through. The technician looks for cracks, and where a crack runs through the surface, crack injection is priced at SAR 40–120 per metre, so the length found is recorded on the spot. Surfaces that need a sealed finish are assessed for epoxy coating at SAR 35–90 per m², while spray foam at SAR 25–35 per m² is considered where a lighter, quicker treatment suits the area. The inspector notes the measured area of each room, which is what the per-square-metre rates are applied to, so the scope of each bathroom is written down before any work is agreed.

Before the visit, the property team should gather a simple record of each bathroom, including its floor area in square metres, the locations where dampness or staining has been seen, and the date of any previous repairs. Access to every room must be arranged in advance, with fixtures and loose items cleared from the floor so that the surfaces can be checked properly. Where a company manages several sites, listing them together with their floor plans lets the inspections run in one planned round instead of separate call-outs. Having this information ready keeps the visit short, makes the written scope easy to compare with the annual budget, and gives the property owner a clear picture of what the contract covers.

For companies, an annual contract sets the scope, the visit schedule and the reports in writing.
