Floor & balcony waterproofing in Baqiq: before summer & rain season

Before we start: what we know about Baqiq

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).

Before any work starts on a floor or balcony in Baqiq, the technician first checks how water will reach the surface. The centre of Baqiq sits about 83 m above sea level, which is a useful reminder that the area is not a low-lying basin where water collects naturally, so the first questions concern drainage falls, the slope of the floor towards outlets, and whether rainwater runs off the balcony edge or pools against the wall. Cracks are the next thing to look at, because a hairline crack that is ignored in dry weather can carry water through in a storm. Where cracks are found, crack injection is typically priced at SAR 40–120 per metre, so the length of each crack is measured early so the scope and cost are clear before any material is chosen.

The detailed decisions are left to the site visit, where the technician can see the substrate and the condition of the existing layers. Whether the surface needs liquid waterproofing, a bitumen membrane, or a coating system depends on what is already there and how it has behaved. Liquid roof waterproofing usually falls within SAR 8–25 per m², bitumen membrane within SAR 15–35 per m², and epoxy coating within SAR 35–90 per m², but the right choice is decided on the spot rather than from a list. The technician also checks whether bathrooms adjoining the balcony need separate work, since bathroom waterproofing is priced at SAR 15–40 per m² and is handled as its own area. Where insulation is needed under a finish, XPS boards at SAR 12–30 per m² may be considered after the surface has been inspected.

To help the technician prepare, it is useful to have the following ready before the visit: a rough sketch of the floor or balcony with its dimensions, the location of drainage outlets and any visible cracks, and a note of when leaks were last seen and whether they appeared during rain or after cleaning. Access to the area should be clear, and any furniture or planters should be moved if possible. Tell the technician if the balcony is used for water storage or sits above a habitable room, as this affects the materials considered. Clear information at this stage shortens the visit and makes the final scope easier to agree.

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