Team note on Aldawadmi: 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 Aldawadmi sits about 976 m above sea level (SRTM open elevation data).

Before any price is discussed on a floor or balcony job in Aldawadmi, the first thing a technician checks is the location itself. The centre of Aldawadmi sits about 976 m above sea level (SRTM open elevation data), and that height is worth noting because it shapes how a surface is prepared and which system suits it. A balcony or floor that is exposed and open to weather may need a different approach from one enclosed inside a building. The technician will also look for existing cracks, since crack injection is priced per metre (SAR 40–120 per m) and the length found on the day decides how much of that work is needed. Liquid roof waterproofing (SAR 8–25 per m²) and bitumen membrane (SAR 15–35 per m²) are common choices for open surfaces, but the choice is made only after the substrate has been inspected.

Several things are left to the site visit because they cannot be judged from a description. The actual condition of the concrete, whether water is already pooling, where drains and outlets sit, and whether the balcony edges show staining or movement all need to be seen in person. The technician will also confirm the area measured in square metres, since every system listed here is charged per m² or per metre, and no total can be given until that figure is taken on site. Where a balcony meets a wall or a floor meets a bathroom, the junction is examined by hand. Spray foam (SAR 20–45 per m²) and epoxy coating (SAR 35–90 per m²) each suit different surfaces, and the final pick depends on what the inspection reveals rather than on a fixed rule.

To help the technician, it is useful to have a few details ready before the visit. Note when leaks first appeared and whether they follow rain or occur after washing. Share any previous repair records, the age of the floor or balcony if known, and whether the area is used for foot traffic, planters or heavy items. Clear access to the surface and to any drains or outlets saves time. If the job also involves a bathroom, a tank or an insulated roof, mention it early, because bathroom waterproofing (SAR 15–40 per m²), tank internal coating (SAR 25–60 per m²) and XPS boards (SAR 12–30 per m²) are separate line items and need their own measurements. Clear information at the start makes the on-site assessment faster and the final quote easier to read.
