Why floor & balcony waterproofing differs in Alzulfi

Team note on Alzulfi: 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 Alzulfi sits about 615 m above sea level (SRTM open elevation data).

Main roads in or near Alzulfi: King Fahd Road, Sheikh Ibn Baz Square, King Salman Road.

The centre of Alzulfi sits about 615 m above sea level (SRTM open elevation data), which means clinic floors and balconies here are shaped by a highland setting rather than a coastal one. On a site visit we start by looking at the slab and the drainage paths, because the height and the local weather both affect how water moves across a balcony or a treatment-room floor. A quick first check covers existing cracks, ponding spots near floor drains, and the junction between the balcony edge and the wall, since these are the places where water usually gets in. Where a crack is active, crack injection is priced per metre at SAR 40–120 per m, so measuring the length of each crack early helps the technician set the scope before anyone commits to a larger system.

Several decisions are left to the site visit itself. The choice between liquid roof waterproofing (SAR 8–25 per m²), bitumen membrane (SAR 15–35 per m²) and spray foam (SAR 20–45 per m²) depends on the substrate condition, the slope of the surface and how much foot traffic the clinic area receives. Epoxy coating (SAR 35–90 per m²) is usually considered for hard-wearing floors where cleaning is frequent, and this should be confirmed on the spot rather than assumed. Where insulation is part of the work, XPS boards (SAR 12–30 per m²) may be discussed, but only once the technician has seen the existing build-up and how the balcony drains. Any basement or tank element is also assessed on arrival, with basement waterproofing at SAR 50–150 per m² and tank internal coating at SAR 25–60 per m² handled as separate items.

To help the technician, note the clinic's opening hours and when the treated area can be closed off, because clinic floors often need to stay in use. Record which rooms are wet areas, such as those with bathroom waterproofing at SAR 15–40 per m², so these can be priced and sequenced separately. Photograph the balcony edges, floor drains and any staining on ceilings below, and mention any past leaks. Clear access to the roof or balcony, and information on who will sign off the work at the clinic, will allow the visit to move quickly and keep the final quotation accurate.

For clinics, work is scheduled around patient hours and kept to the areas that need it.
