What is specific about Rastanura for floor & balcony waterproofing

Rastanura is about 0.2 km from the sea coast (OpenStreetMap). Team note on Rastanura: 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..

Imagine a family that owns a flat in a residential block on the edge of the city. The owner notices a damp patch spreading across the ceiling of the balcony below, and small cracks appearing where the balcony slab meets the wall. They are not sure whether the problem is coming from the floor above, the balcony surface, or the joints around the railings. Like many owners of apartments and houses, they want to fix the leak properly before it reaches the rooms inside.

Rastanura is about 0.2 km from the sea coast (OpenStreetMap), and that closeness matters. Salt-laden air and moisture can work into concrete and render over time, so surfaces that look sound may still let water through. For this owner, the location is a reason to treat the balcony and floor as exposed surfaces that need a durable seal rather than a quick cosmetic patch. Owners should also check whether the damp appears after rain or after humid weather, since that pattern helps show where water is entering.

A sensible order of work starts with a careful inspection. Walk the balcony and mark every crack, check the drainage outlets, and look at the junction with the wall and the railing base. Next, repair the cracks, because crack injection is priced per metre (SAR 40–120 per m), and that step stops water from using the existing gaps. Then choose the membrane or coating for the open surfaces: bitumen membrane (SAR 15–35 per m²) or liquid roof waterproofing (SAR 8–25 per m²) are common options, while epoxy coating (SAR 35–90 per m²) suits surfaces that need a harder finish. Where a bathroom sits above the affected area, bathroom waterproofing (SAR 15–40 per m²) should be included in the same plan. Finish by checking that water runs away from the surface and that the new layer is protected from traffic and furniture.

For a residential building, shared risers, tanks and pumps are checked as one system.
