What is specific about Riyadh for floor & balcony waterproofing

Team note on Riyadh: 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.. Main roads in or near Riyadh: King Fahd Road, King Abdullah Road, King Abdullah.

The centre of Riyadh sits about 637 m above sea level (SRTM open elevation data).

The first thing we check on a clinic floor or balcony in Riyadh is the drainage and the slope of the surface, because the city's location shapes how water moves across a roof and balcony. The centre of Riyadh sits about 637 m above sea level (SRTM open elevation data), so the technician looks at where rainwater will collect after a storm and whether it can run off freely. Clinics add their own pressure: frequent wet cleaning, sterilisation water, and heavy foot traffic in corridors and treatment rooms all mean the surface must be sound before any coating goes on. Cracks, lifted tiles and old sealant are noted first, since they decide whether a crack injection (SAR 40–125 per metre) or a full liquid system is the right route.

Some points can only be settled on the site visit. The technician must measure the real area, confirm which floors are wet rooms and which are dry offices, and check whether the balcony is exposed or sheltered. Substrate moisture, the condition of existing membranes, and whether an old bitumen membrane (SAR 15–35 per m²) is still bonded or has blistered are all judged by eye and by touch on the day. The choice between epoxy coating (SAR 35–95 per m²), spray foam (SAR 20–45 per m²) or liquid roof waterproofing (SAR 10–25 per m²) depends on traffic, slope and access, so the final recommendation waits until the surface has been inspected in person. Pricing ranges quoted for these systems are indicative only until the measured scope is confirmed.

To help the technician prepare, the clinic should note the room layout, any sections that must stay in use during work, and the hours when noise and disruption are acceptable. It is useful to record previous leaks, the location of floor drains and outlets, and whether insulation such as XPS boards (SAR 15–30 per m²) already sits beneath a balcony or roof deck. Access routes for materials, and any areas where tank internal coating (SAR 25–65 per m²) or basement waterproofing (SAR 55–160 per m²) is also needed, should be flagged in advance. Clear information at this stage shortens the visit and makes the final scope and cost easier to agree.

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

Signs worth paying attention to

• Water passing from the balcony to the floor below

The most common causes

• A common cause: a blocked drain.
• Incorrect falls — we check this before anything else.
• A threshold without waterproofing — we check this before anything else.
