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..

The most common problem with bathroom waterproofing in Afif is water that gets past the tiles and into the screed, usually at the shower floor, the junction between floor and wall, and around drain outlets. Because the damage happens under the surface, it often goes unnoticed until stains appear on the ceiling of the room below or the paint starts to lift. Bathroom waterproofing in this area is typically priced at SAR 15–40 per m², and a good starting point is to treat the shower area and the floor-to-wall joints as the priority zones rather than only the dry parts of the floor.

Afif sits at about 1040 m above sea level, and that altitude shapes the approach. Summers here are milder than in the lowlands, so the main stress on a bathroom is not heat alone but the wet-dry cycles of daily use combined with the rain season. Rain arriving after a dry period can find small cracks in old tiling grout and push water into areas that seemed sound. For this reason, the preparation work matters as much as the membrane itself: the substrate should be checked for cracks, and any cracks should be sealed before the waterproofing layer goes down. If cracks are present in the wall or floor, crack injection, priced at SAR 40–120 per metre, is often considered first. Where a full coating is chosen, epoxy coating at SAR 35–90 per m² or a bitumen membrane at SAR 15–35 per m² are common options, and the right choice depends on the condition of the existing surface.

Before the visit, it helps to have a few answers ready. Ask which parts of the bathroom will be covered, specifically whether the shower tray, the wall junctions and the drain are included. Ask what surface is currently under the tiles and whether any cracks, damp patches or hollow-sounding tiles have been noticed. Ask whether the work will be priced per square metre for the full bathroom or only for the wet zones. Finally, ask how long the area should be kept out of use afterwards and whether a water test can be carried out before the new tiles are fixed. Clear answers to these questions make the site visit more useful and the quote easier to compare.

Checks before summer and before the rain season catch problems while they are still small.
