Picture a family that has lived in a residential apartment block in Afif for several years. The bathroom floor is tiled, the walls are painted, and everything looks fine until a damp patch appears on the ceiling of the flat below, or a faint smell of mould starts creeping along a corner. For many owners in this situation, the problem has been building quietly behind the tiles for a long time, and the first sign is rarely the source.
The local setting matters. The centre of Afif sits about 1040 m above sea level, so buildings here deal with a different climate and rainfall pattern than coastal cities. Bathrooms in these blocks are often the weakest point for water, because showers, drains and joints around fixtures take constant wear. Cost also shapes choices: bathroom waterproofing typically falls in the range of SAR 15–40 per m², while epoxy coating runs SAR 35–90 per m² and spray foam SAR 20–45 per m². Knowing these ranges helps owners compare quotes sensibly and ask why one method is priced above another.
A practical approach starts with inspection. Look for stains, peeling paint, hollow-sounding tiles and cracks, and note any water that lingers near the shower or drain. If cracks are present, crack injection, priced at SAR 40–120 per metre, is often the first repair, so the path forward is not blocked. Next, decide the coating: a bitumen membrane (SAR 15–35 per m²) or liquid-applied system suits many wet areas, while XPS boards (SAR 12–30 per m²) are usually reserved for insulation-focused work. Finally, schedule the work so the surface is clean and dry before coating, allow full curing time, and retest the area with a short water test before retiling. Keep written records of each step for future reference.
For a residential building, shared risers, tanks and pumps are checked as one system.
