Before any price is discussed on a floor or balcony job in Samtah, the first thing checked is where the site sits in the landscape. The centre of Samtah sits about 61 m above sea level (SRTM open elevation data), and the town is about 22.6 km from the sea coast (OpenStreetMap). Those two facts shape how water moves across a roof, balcony or floor slab, so the technician notes slope, drainage outlets and any low corners where water could pool after rain. Because the town is inland rather than on the coast, the first checks focus on the surface drainage and the existing waterproof layer rather than on salt exposure from the shore.

Several things cannot be judged from a description and are left to the site visit. The technician walks the balcony or floor, looks for hairline cracks, lifting tiles, failed sealant around drains and doors, and signs of water staining below. He or she checks whether the existing membrane is still bonded or has blistered, and decides whether a crack needs injection or the surface needs recoating. Access, the state of the substrate and the amount of prior coating to be removed all affect the final scope, so no firm measurements are fixed until the area has been inspected in person.

Information that helps the technician can be gathered before the visit. It is useful to know the approximate area of each floor or balcony surface, the length of any visible cracks, and whether the space is a bathroom, a roof, a balcony or a below-ground basement, since each use is priced differently in the published ranges. Published ranges for reference are SAR 15–40 per m² for bathroom waterproofing, SAR 8–25 per m² for liquid roof waterproofing, SAR 15–35 per m² for bitumen membrane, SAR 20–45 per m² for spray foam, SAR 35–90 per m² for epoxy coating, and SAR 40–120 per metre for crack injection. Final quotes depend on what the visit finds.
