Floor & balcony waterproofing in Qatif: the local context

Team note on Qatif: 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.. Qatif is about 2.5 km from the sea coast (OpenStreetMap).

The centre of Qatif sits about 5 m above sea level (SRTM open elevation data).

Is a leaking floor or balcony in Qatif an emergency that needs a crew straight away? Qatif sits about 5 m above sea level, and the sea coast is roughly 2.5 km away, so the ground here is not as low-lying as many coastal areas, yet damp salty air and seasonal rain can still push water into slabs, junctions and balcony edges. A visible wet patch, a stain spreading across a ceiling below a balcony, or water appearing at a floor joint are signs that the barrier has failed and that the problem should be looked at promptly rather than left to worsen.

When a crew comes out, the inspection usually starts with tracing where the water is actually entering, since the wet patch is often some distance from the true source. The technician checks cracks and joints, looks at the drainage outlets and upturns at the edges, and measures the affected area so the scope can be set out clearly. Where a crack is the likely route, the crew can measure its length in metres, because crack injection is priced per metre. For larger areas, the surface is measured in square metres. Based on what is found, the crew then recommends a suitable system, whether that is a liquid roof waterproofing layer, a bitumen membrane, an epoxy coating, or spray foam, and explains the work in plain terms before anything starts.

Before the visit, it helps to clear the area around the leak so the technician can reach the cracks and edges easily, and to move furniture or stored items away from the wet zone. Note when the leak appears, whether after rain, after cleaning, or during a particular season, as this helps pinpoint the cause. Take photographs of the stains and any visible cracks, and tell the crew which floor or balcony is affected and whether the water reaches rooms below. Having these details ready lets the visit move quickly and gives you a clearer picture of the work before you agree to anything.

If water is flowing, close the main valve first, then call or message with photos.
