Is it worth waterproofing the bathrooms in our office block before leaks start causing damage? In Afif, where the centre of town sits about 1040 m above sea level, many property owners ask this when they notice staining or soft plaster near wet areas. Bathroom waterproofing for offices and commercial complexes is priced at SAR 15–40 per m², which is a modest cost compared with repairing ceilings, fixtures and the floors below. Where the wet area is also a basement or tank room, the rates differ: basement waterproofing runs at SAR 50–150 per m², and tank internal coating at SAR 25–60 per m². Our guidance is to match the treatment to the surface and the exposure rather than choosing one method for the whole building.

Before any work is quoted, the inspection follows a set sequence. The technician first walks the bathroom and adjoining areas to check floor slopes, drainage points and the condition of tiles and grout. Any cracks are recorded, and where a crack is active, crack injection is priced at SAR 40–120 per metre, so its length is measured accurately. Surfaces are then assessed for the right system: 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 each suit different substrates and levels of movement. The inspector notes the area in square metres for each zone, so the quotation reflects the real extent of the work rather than an estimate.

To make the visit efficient, gather a few details beforehand. Note which bathrooms or wet rooms show staining, dampness or flaking paint, and mark any spot where you have seen water coming through from above or below. Have drawings or a simple sketch of the floor plan, including the basement and any water storage tanks, if these sit close to the bathrooms. Clear access to floor drains and the area beneath sinks, and let the occupants of the offices know when the inspection will take place so that the space can be reached without disruption. With these preparations, the inspection can move straight to a clear, itemised proposal.

For offices and commercial complexes, work is scheduled to avoid disrupting staff and visitors.
