Before we start: what we know about Afif

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..

Picture a family who has just moved into a villa in Afif. The bathrooms look fine at first, but after a few months the paint near the shower bubbles, a damp patch appears on the wall behind the tub, and the owner wonders whether the problem is hidden under the tiles. Many owners in this situation only notice the damage once water has already reached the wall structure, which makes the repair more involved than it needed to be.

Afif sits at about 1040 m above sea level, which means the town is high and fairly cool compared with the lowlands, yet the same bathroom habits still produce the same wet conditions. For a villa owner, the lesson is that altitude does not protect a bathroom from water. Daily showers, splashing at the edges of the tub, and condensation on cold tiles all push moisture into grout and joints. Bathroom waterproofing typically costs SAR 15–40 per m², so treating the wet zones early is a modest expense compared with the cost of opening up finished walls later.

Start by checking the bathroom floor, the wall at the shower and the joints around the tub, looking for dark staining, soft plaster or lifting tiles. Next, mark every area where water regularly reaches, and measure those surfaces in square metres so you can compare quotes on a per m² basis. Where cracks appear in the walls, have them sealed by crack injection, which is usually priced per metre at SAR 40–120 per m, before the surface is treated. Choose a waterproofing system suited to the surface, such as a liquid membrane or epoxy coating in the wet zones, and let each layer cure fully before tiling. Finally, keep grout lines sealed and check them every year, because a small gap repaired early in Afif costs far less than a wall repaired after the water has spread.

Villas often have several lines and tanks; we test them one at a time so the cause is clear.

Signs worth paying attention to

The following signs are worth checking before they grow:

• A stain under the bathroom on the floor below
• Damp around the shower
• Worn grout

Where the problem usually comes from

• Corners without waterproofing tape — we check this before anything else.
• A common cause: a damaged floor layer.
• The area around the floor drain.

Tools and methods, and when we use them

The steps in order

1. Finding the source: A supply-pipe leak is ruled out first.
2. Preparation: The floor is opened and cleaned where needed.
3. Corners and details: Tape and detailing at corners, drains and pipe entries.
4. Flood test: The floor is tested before tiling.
