What is specific about Rastanura for floor & balcony waterproofing
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.. Rastanura is about 0.2 km from the sea coast (OpenStreetMap).
Rastanura sits about 0.2 km from the sea coast, according to OpenStreetMap, so salt-laden air and damp ground are the first things a technician checks on any school floor or balcony here. Coastal moisture can work into slabs and tile joints faster than in inland areas, so the surface is inspected for hairline cracks, blistering, and staining before any product is chosen. Where salt efflorescence shows, the substrate needs cleaning and drying before a membrane or coating goes on, because trapped moisture will push a new layer off the surface.
Several things are left to the site visit, because they cannot be judged from a description. The technician measures the actual area and confirms whether the balcony drains freely or pools water at the edges. They check whether the problem is surface-level or whether it comes from a crack that runs through the structure, which decides between a simple liquid roof waterproofing system and a crack injection repair. Access to the work area, the times when children are in the building, and whether classrooms can be closed off for the curing period are also agreed on site, since school schedules shape how the job is planned.
To help the technician, it is useful to know which areas of the school have had leaks, ponding, or peeling paint, and when the problem was first noticed. Photographs of stains and any previous repair work are valuable. Information on whether the balcony is tiled, screeded, or bare concrete changes the preparation needed. For reference, liquid roof waterproofing is priced at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², and crack injection at SAR 40–120 per metre, so knowing the rough extent of the cracks and the surface area helps the technician suggest a sensible scope before the visit.
For schools, the larger jobs are planned for weekends and holidays.

Tools and methods, and when we use them

|---|---|---|
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
From the first visit to the report
- Checking the falls: Where water collects and where it should go.
