Floor & balcony waterproofing in Aljumum: the local context
Team note on Aljumum: 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.. The centre of Aljumum sits about 200 m above sea level (SRTM open elevation data).
Picture a restaurant owner in Aljumum who has just opened a dining terrace above a busy kitchen. The floor tiles look fine, but after the first rainy week a damp patch appears on the ceiling below and the balcony railing edge shows dark streaks. The owner wants the problem fixed before the next season of guests arrives, without closing the dining room for longer than necessary.
The centre of Aljumum sits about 200 m above sea level (SRTM open elevation data), which means the area is not a low-lying basin where water collects at the foot of buildings. Water that falls on a restaurant roof or balcony tends to run off quickly, so the real risk is slow seepage through cracks, joints and poorly sealed edges rather than standing floodwater. For an owner, this means the first job is finding where water actually enters. Liquid roof waterproofing, typically priced at SAR 8–25 per m², suits large open roof areas, while crack injection at SAR 40–120 per m is the right answer for a single hairline split in a balcony slab.
Start by walking the balcony and roof after a shower of rain and marking every wet line, crack and failed sealant joint. Next, clear loose tiles and dust from the marked areas and repair the cracks by injection before any surface coating goes on. Then choose the coating that matches the surface: bitumen membrane at SAR 15–35 per m² for flat roofs, epoxy coating at SAR 35–90 per m² where a durable, easy-clean finish is needed on a balcony floor that takes foot traffic. Where the kitchen sits directly beneath a wet area, consider spray foam at SAR 20–45 per m² on the underside for added protection. Finish by re-sealing the drainage outlets and checking that the falls direct water away from the restaurant entrance. Keep dated photos of each stage so the work can be reviewed later.
For restaurants, visits are planned outside service hours and recorded for the premises file.
