Floor & balcony waterproofing in Jazan: the local context

Team note on Jazan: 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.. Jazan is about 1.9 km from the sea coast (OpenStreetMap).

The centre of Jazan sits about 7 m above sea level (SRTM open elevation data).

Balcony and floor leaks in Jazan usually start where water finds a way through a hairline crack or a worn joint, then spreads unseen into the slab below. In an emergency, the first sign is often a damp patch on a ceiling under a balcony or a soft, discoloured strip along a floor edge. Because the damage is hidden, the leak often runs for some time before anyone notices it. Our emergency visit focuses first on stopping the water path, then on checking how far the moisture has travelled.

Local conditions shape how we approach the job. The centre of Jazan sits about 7 m above sea level, and the city is about 1.9 km from the sea coast. That combination means the air carries salt and humidity, which can slowly break down old sealants and surface coatings. For that reason we look closely at the edges of the balcony and the junction with the wall, not only the middle of the floor. Where a crack is active, we may recommend crack injection, which we price at SAR 40–120 per metre, so the repair reaches the depth of the fault rather than only sealing the surface. For a balcony floor with a broad exposed area, a liquid membrane or spray foam may be a better fit, and the cost depends on the area and the material chosen.

Before the visit, ask a few clear questions so the team arrives prepared. Tell us the exact location of the wet area, whether it is a balcony, a floor, or a bathroom above, and whether water appears after rain or during use. Ask whether the leak has reached a ceiling or a neighbouring unit, since that affects the scope. Share any earlier repair work, because old coatings can need removal before new material bonds properly. Finally, ask for a written breakdown of the proposed method and the price per square metre or per metre of crack, so you can compare options with the facts in hand before work begins.

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