Basement and foundation waterproofing work in Alrass begins with the ground itself. The centre of Alrass sits about 695 m above sea level (SRTM open elevation data), so the first check is how water is likely to move across and below the plot. Technicians look at where rainwater runs off the surrounding ground, whether the basement wall sits lower than the adjacent path or drainage line, and whether there is any sign of standing water after rain. Before any quotation is given, the wall and floor are inspected for dampness, staining and efflorescence, because these show where moisture is already reaching the structure.

What is left to the site visit is the detail that cannot be judged from a description. Technicians assess the actual wall area and floor area that need treatment, since the price of basement waterproofing is usually quoted per m², in a range of SAR 50–150 per m² depending on the system and condition. They check each crack and measure its length, because crack injection is quoted per metre at SAR 40–120 per m. They also decide between options such as epoxy coating (SAR 35–90 per m²), spray foam (SAR 20–45 per m²) or XPS boards (SAR 12–30 per m²), and they confirm whether any tank or bathroom sits within the work zone, which would add bathroom waterproofing at SAR 15–40 per m² or tank internal coating at SAR 25–60 per m².

To help the technician, it is useful to have ready a sketch or list of the basement dimensions, the locations of visible cracks and damp patches, any previous repair work, and the approximate date when water was first noticed. Information about nearby ground levels, roof areas draining toward the basement, and whether a bitumen membrane (SAR 15–35 per m²) or liquid roof waterproofing (SAR 8–25 per m²) has already been applied elsewhere on the property also helps. Clear answers on these points let the technician plan the right system and give a more accurate estimate.
