Why basement & foundation waterproofing differs in Aldawadmi

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).

For hotels and serviced apartments in Aldawadmi, the most common foundation problem is water finding its way into basements and lower-floor store rooms, usually through hairline cracks in the lower walls and at the joint where the wall meets the floor slab. Guests rarely see this directly, but damp patches, musty smells and efflorescence on the walls quickly affect the experience and the upkeep budget. Our basement and foundation waterproofing service targets these entry points rather than treating the whole structure as one surface.

Local conditions shape how we approach each job. The centre of Aldawadmi sits about 976 m above sea level (SRTM open elevation data), so the site is on a higher inland plateau rather than in a low-lying coastal area. That matters because surface water is more likely to run toward and pool against lower walls during heavy rain, and the approach has to account for that flow. In practice, this points toward a combination of crack injection where the structure has split, and a membrane or board system across the wall face. Basement waterproofing is priced at SAR 50–150 per m², crack injection at SAR 40–120 per metre, and XPS boards at SAR 12–30 per m², so the mix of methods changes the final scope and cost considerably.

Before the visit, ask the team a few practical questions. Confirm which areas are affected: basement walls, the slab, adjacent plant rooms or the bathrooms above them, since bathroom waterproofing (SAR 15–40 per m²) and epoxy coating (SAR 35–90 per m²) are often needed in the same project. Ask whether the cracks are active or old, whether the water comes in during rain or from the ground, and whether any water storage tanks sit nearby, since tank internal coating (SAR 25–60 per m²) is priced separately. Finally, ask for a written breakdown per m² and per metre so you can compare each line item against the ranges above.

For hotels and serviced apartments, rooms are handled in batches to keep units available.
