Does an apartment basement in Baqiq really need waterproofing, and how do you know where the water is getting in? The centre of Baqiq sits about 83 m above sea level, according to SRTM open elevation data, so the area is not a low-lying hollow where water pools naturally. Leaks in a basement usually come from cracks, failed joints or pressure from the ground outside, not from the surface level itself. Basement waterproofing in this work is priced at SAR 50–150 per m², and the final figure depends on how much wall and floor area is affected and how the existing surfaces are prepared.

Our inspection starts with a walk through the basement and the adjoining bathrooms to identify damp patches, staining, efflorescence and cracks. The technician measures the affected areas so the scope can be quoted by the square metre. Where cracks are visible, they are recorded by length, since crack injection is charged at SAR 40–120 per metre. Other options are then matched to the conditions found: epoxy coating at SAR 35–90 per m², spray foam at SAR 20–45 per m², or XPS boards at SAR 12–30 per m² where a board system suits the wall. Bathrooms are checked separately, with bathroom waterproofing at SAR 15–40 per m², and any water tanks on the property are assessed for tank internal coating at SAR 25–60 per m². Roof areas, if they are part of the same complaint, are inspected for liquid roof waterproofing at SAR 8–25 per m² or bitumen membrane at SAR 15–35 per m².

Before the visit, clear as much of the basement as you can so the walls and floor are reachable, and note when water appears, such as after rain, during irrigation or when the building's water supply runs. Keep any previous repair records or invoices, and tell the technician which rooms are affected and whether the damp has spread since it was first noticed. Mark the spots you already suspect, and make sure someone with access to the property can let the inspector in. With these details ready, the quote can match the actual problem in your apartment building in Baqiq.
