Before you buy or take over a home in Khafji, the first thing to note is where the property sits. The centre of Khafji is about 9 m above sea level (SRTM open elevation data), and the town is about 2 km from the sea coast (OpenStreetMap). Because the land is low and close to the coast, surface water and salty air can reach floors and balconies more readily than on higher inland ground, so the condition of the existing waterproofing deserves a close look from the start. Check whether any patches of floor or balcony show lifting, darkening, or a soft feel underfoot, and ask the seller when the layer was last renewed and by whom.

Some points are better judged on the day of the site visit than from paperwork. A technician should walk every balcony and wet area, test for hollow sounds by tapping the tiles, look for cracks and their direction, and confirm whether the drainage outlets run freely. Water staining on the ceiling below a balcony, or a crack that reopens after cleaning, tells you more than any written statement. The technician will also decide which system suits each surface. Common options include liquid roof waterproofing, bitumen membrane, spray foam, epoxy coating, and crack injection, and the right choice depends on what they find under the surface and how the area is used.

To help the technician prepare an accurate assessment, gather the basics before the visit: the approximate floor area of the balconies and wet rooms, the age of the building, any previous repair records, and whether the property has a basement or a water tank that also needs attention. Point out any spots that have leaked in the past and note where furniture or fixtures sit against the walls. Ask whether earlier work used a membrane or a coating, since the new system must bond properly to what is already there. Clear, specific information lets the technician price the job realistically and avoid surprises once work begins.

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