Is the balcony or floor you are about to buy in Samtah already sealed, and what would it cost to fix if it is not? Samtah sits about 61 m above sea level, and its centre is about 22.6 km from the sea coast, so the town is not on the shoreline but still has its own rainfall and moisture exposure to plan for. Before you agree a price, a balcony or floor that has been waterproofed should show clear evidence of it, and the cost of any repair should be known in advance. Typical rates in the facts include liquid roof waterproofing at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², spray foam at SAR 20–45 per m², and epoxy coating at SAR 35–90 per m², while crack injection is priced at SAR 40–120 per metre.

A sensible inspection starts with the surfaces that take the most water. Walk the balcony and floor slowly and look for hairline cracks, dark or stained patches, peeling paint and any soft or powdery concrete. Measure the area in square metres so you can estimate the cost of coating or membrane work at the rates above. Any crack should be measured in metres, because crack injection is charged per metre. Check the junctions where the floor meets the wall, the drainage points and the edges of the balcony, since water commonly enters at these joints. If the property has a bathroom next to the balcony, note its condition too, since bathroom waterproofing is priced separately at SAR 15–40 per m². Where a water tank or basement is part of the building, ask to see its interior, because tank internal coating runs at SAR 25–60 per m² and basement waterproofing at SAR 50–150 per m².

Before the visit, gather the documents and information that will make the inspection useful. Ask the seller or developer for any earlier waterproofing records, warranty papers and the name of the material used if it is known. Prepare a rough floor plan with the balcony and floor areas marked so you can calculate the likely cost range quickly. Bring a torch, a notebook and a camera or phone to record each defect with its location. If the visit is during or just after rain, look for active leaks, since they are easier to spot than old staining. Having these details ready lets you negotiate on real figures and decide whether the repairs should be agreed before handover.

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