Basement & foundation waterproofing for offices & commercial complexes in Madinah

Before we start: what we know about Madinah

The centre of Madinah sits about 589 m above sea level (SRTM open elevation data). Team note on Madinah: 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..

Madinah sits at about 589 m above sea level, which is a useful starting point for any basement or foundation job across the city. Before quoting, the technician first checks how the ground and the building sit together: whether the lower floors are below the water table, how the surrounding levels drain, and where water already shows through walls or slab joints. Elevation affects how water moves across a site, so the drainage route around the building is often the first thing to confirm. Cracks in the basement wall or floor are then mapped, since crack injection is priced per metre and needs an accurate length before work begins. The likely treatment is then set against the commercial use of the space, because offices and shops need the work done with the least disruption to daily trading.

What is left to the site visit is the part that cannot be judged from a drawing. The technician will look at the actual condition of the concrete, the type of soil against the walls, and whether the existing waterproofing is still bonded or has already failed. Access matters too: how tight the basement is, where materials can be stored, and whether work can be done in stages so that tenants keep their floors in use. The choice between a basement waterproofing system priced at SAR 50–150 per m², an epoxy coating at SAR 35–90 per m², or spray foam at SAR 20–45 per m² depends on what the inspection reveals. Roof areas that connect to the foundation drainage are also checked at this stage, since liquid roof waterproofing at SAR 10–25 per m² or a bitumen membrane at SAR 15–35 per m² may be part of the same problem.

To help the technician prepare, the client should gather the building's age, any previous waterproofing records, and a rough plan showing the basement footprint and visible cracks. Note where water appears after rain and whether it comes from the walls, the floor, or the joints. If the site includes a water tank, mention it early, because tank internal coating is priced separately at SAR 25–60 per m² and needs its own access arrangements. Sharing these details in advance lets the visit focus on the real conditions rather than guesswork, and it gives the client a clearer picture of the scope before any work starts.

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