Before we start: what we know about Alqunfudhah

Team note on Alqunfudhah: 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 Alqunfudhah sits about 7 m above sea level (SRTM open elevation data).

Alqunfudhah is about 0.4 km from the sea coast (OpenStreetMap).

Does a basement in Alqunfudhah really need waterproofing before you buy, and what should you check first? The town's location answers much of that question. The centre of Alqunfudhah sits about 7 m above sea level, and it lies about 0.4 km from the sea coast. Being so close to the coast means the ground and groundwater around a basement can behave differently from inland sites, so a property owner here should treat the foundation and any below-ground walls as a priority, not an afterthought.

Before you commit to a purchase, ask a specialist to inspect the basement and foundation walls on site. A sensible visit starts with a walk through the lowest level, looking for damp patches, staining, efflorescence and any cracks in the walls and floor. Cracks are costed per metre, at SAR 40–120 per m for crack injection, so the inspector should measure the length of every visible crack and note whether each one runs through the wall or only across the surface. The inspector then records the total area of basement wall and floor, since basement waterproofing is priced at SAR 50–150 per m². Bathrooms and roofs should be checked as well, because bathroom waterproofing runs at SAR 15–40 per m² and liquid roof waterproofing at SAR 8–25 per m². Ask which methods suit each area, such as epoxy coating at SAR 35–90 per m², spray foam at SAR 20–45 per m², or a bitumen membrane at SAR 15–35 per m².

To make the visit productive, prepare a few things in advance. Gather any previous repair records, the building's age and any notes on past water problems. Clear the basement as far as you can so the walls and floor are visible, and note where water appears after rain or when the nearby ground is wet. Have a rough plan of the basement with dimensions, so the inspector can estimate areas quickly. Finally, write down your questions about the methods, the materials and the scope of work, so the inspection leaves you with clear figures you can compare before you decide.

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

Tools and methods, and when we use them

The steps in order
