Bathroom waterproofing in Afif: the local context

The centre of Afif sits about 1040 m above sea level (SRTM open elevation data). Main roads in or near Afif: King Abdulaziz Road, King Faisal Road, Airport Road.

Team note on Afif: 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..

For companies that run staff accommodation, serviced offices or hospitality sites in Afif, the most common bathroom problem is water getting under floor tiles and into the wall behind them. Over time this lifts grout, stains ceilings below and causes damp smells that staff notice quickly. In a contract covering many bathrooms, a single leak that goes unseen can affect several rooms at once, so the aim of a planned programme is to find weak spots before they spread rather than to react after complaints arrive.

Afif sits at about 1040 m above sea level, which matters for the approach. At this elevation, temperatures can swing more sharply between day and night than in lower coastal areas, and that movement stresses tile bonds and hairline joints. Bathroom waterproofing here is usually priced at SAR 15–40 per m², and the right system depends on the room. A liquid membrane or epoxy coating may suit wet areas that see constant splashing, while a bitumen membrane can be a sound choice behind a shower tray. Where a crack runs through the floor or wall, crack injection at SAR 40–120 per metre is often the first step, so the seal is made before any surface coating goes on. Because one contract may cover rooms with very different needs, the scope should be agreed room by room rather than applied as a single rate.

Before the visit, ask the provider to confirm which rooms are included and how many bathrooms are on the list, so the survey covers the full set. Ask which system they propose for each wet area and why, and whether the price quoted is per m² on the measured area. Request a written note of how cracks will be treated and how the surface will be tested after curing. Ask how the contract handles follow-up visits, and whether any extra work is charged separately. Finally, ask for a timetable that keeps the rooms out of use for the shortest possible time, so guests and staff are not left waiting.

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