What is specific about Alrass for floor & balcony waterproofing

Team note on Alrass: 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 Alrass: King Abdulaziz Road, King Fahd Road, King Salman Road.

The centre of Alrass sits about 695 m above sea level (SRTM open elevation data).

Is a floor or balcony in Alrass dry enough to buy, or does it need waterproofing before handover? Alrass sits at about 695 m above sea level, according to SRTM open elevation data, and that height does not by itself tell you whether water is getting through. What matters is the surface and the joints, so the answer comes from checking them rather than assuming. The cost figures below show the typical range for common works, so you can judge a quote against what the job should roughly involve.

A practical inspection starts with the balcony and floor surfaces, looking for cracks, lifted tiles, and poor edges where the floor meets walls. Crack injection is priced per metre, typically SAR 40–120 per m, so measure any visible cracks and note their length. Check the bathroom floor and walls next, since bathroom waterproofing runs SAR 15–40 per m², and look for staining on the ceiling below. If the unit has a basement, examine the walls and floor for damp, because basement waterproofing ranges from SAR 50–150 per m². Where a roof or terrace is included, check for pooling and cracks, as liquid roof waterproofing is SAR 8–25 per m², while bitumen membrane is SAR 15–35 per m². Ask whether any water tank has an internal coating, which is SAR 25–60 per m², and look for flaking or staining inside the tank.

Before the visit, prepare a simple sketch of the floors, balcony and roof with rough measurements in square metres and any crack lengths in metres. Bring photos of any damp patches, and note the dates you first saw them, so the inspector can focus on the right spots. Ask the seller or landlord for any previous waterproofing records and the names of the materials used, since epoxy coating (SAR 35–90 per m²), spray foam (SAR 20–45 per m²) and XPS boards (SAR 12–30 per m²) each suit different conditions. With these details ready, your quote and your inspection will be far easier to compare and act on.

Before buying or taking over a property, an inspection gives you findings in writing before you sign.
