Bathroom waterproofing in Baqiq: the local context

Team note on Baqiq: 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.. Main roads in or near Baqiq: King Fahd Road.

The centre of Baqiq sits about 83 m above sea level (SRTM open elevation data).

Bathroom waterproofing in Baqiq starts with the ground the building stands on. The centre of Baqiq sits about 83 m above sea level (SRTM open elevation data), so the first check is how water moves across and through the site rather than how much rain falls on it. Technicians look at the floor falls, the drain positions, and whether water from the shower area runs toward the outlet or pools at the edges. Because bathroom waterproofing is priced at SAR 15–40 per m², the scope of work is usually agreed after this first look, with the membrane choice matched to the floor and wall finishes already in place.

Several points are left to the site visit, because they cannot be judged from a description. These include the condition of the existing screed, any hairline cracks in tiles or walls, and whether the shower tray is sloped correctly. The technician will also check whether the bathroom sits above a habitable room, which affects how far the membrane must rise up the walls and how the junction with the floor is sealed. Where cracks are found, crack injection is quoted at SAR 40–120 per metre, and the decision to inject, coat, or cut back depends on the width and movement seen on the day. Spray foam at SAR 20–45 per m² and liquid systems at SAR 8–25 per m² are options for roofs and open areas, while epoxy coating at SAR 35–90 per m² suits wet rooms that need a harder, more continuous surface.

Information that helps the technician prepares the work. Tell us which rooms are above other living spaces, when the bathroom was last tiled, and whether you have noticed damp patches, soft plaster, or water on the floor after rain. Note the approximate size of the bathroom and any adjoining balcony, so the area can be measured accurately. Photographs of the floor, the drain, and any visible cracks are useful before the visit. Clear access to the bathroom and details of any fixtures that will need to be removed help the work start on time and keep the costs in the expected range.

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

Signs worth paying attention to

The following signs are worth checking before they grow:

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

Causes we see in the field

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

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.
