Before we start: what we know about Muhayil Aseer

Team note on Muhayil Aseer: 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 Muhayil Aseer sits about 455 m above sea level (SRTM open elevation data).

Main roads in or near Muhayil Aseer: King Faisal Road, King Abdulaziz Road.

For offices and commercial buildings in Muhayil Aseer, the most common basement and foundation problem is water entering through cracks and wall-to-floor joints after rain, then spreading across storage rooms, server areas and parking levels. Water pressure against below-ground walls builds up over time, so a small hairline crack can become a steady leak that damages stock, finishes and equipment. For this reason, the first step is usually to identify where water is actually entering, rather than treating the whole basement as one surface.

The centre of Muhayil Aseer sits about 455 m above sea level, which shapes how water moves around a site. Rainwater runs down from higher ground and collects against foundations, so drainage around the building and the condition of the wall surface matter as much as the membrane itself. Our approach therefore starts with the walls and joints that receive the most water pressure. Where cracks are active, crack injection is priced per metre, typically SAR 40–120 per m, and can be combined with a membrane system on the wider wall area, which is priced per m² at SAR 50–150 for basement waterproofing. Where a basement is used for storage of water or tanks, tank internal coating is priced at SAR 25–60 per m². Roof areas above offices are handled separately with liquid roof waterproofing at SAR 8–25 per m².

Before the visit, ask the provider to confirm which areas are wet and how often, and to note any cracks, staining or efflorescence you have already seen. Ask whether the quote covers wall surfaces only or also floor-to-wall joints, and whether crack injection is included or priced separately per metre. Request a breakdown by square metre and by linear metre so you can compare each element clearly. Finally, ask how the site will be kept in use during work, since commercial basements often hold equipment that needs protection while the surfaces are prepared and coated.

For offices and commercial complexes, work is scheduled to avoid disrupting staff and visitors.
