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..

Alqunfudhah is a coastal town, and that shapes where water tends to go. The centre sits about 7 m above sea level, and the sea coast is roughly 0.4 km away, so a basement or foundation wall here can be close to the water table and exposed to salty ground moisture. When you call a technician, the first thing they will check is whether the lower walls and floor show signs of seepage, efflorescence (white salt deposits), or damp patches after rain, since these point to moisture moving in from the ground rather than from a leaking pipe. They will also look at the junction between the floor slab and the walls, where cracks most often appear.

Several things are left to the site visit, because they cannot be judged from a phone call. The technician will need to measure the basement or foundation area in square metres and any cracks in metres, since pricing for basement waterproofing runs at SAR 50–150 per m², while crack injection is charged at SAR 40–120 per metre. They will decide which system fits the damage: epoxy coating (SAR 35–90 per m²), spray foam (SAR 20–45 per m²), or XPS boards (SAR 12–30 per m²) are each suited to different surfaces and levels of water pressure. They will also assess whether a tank or bathroom nearby needs its own treatment, with tank internal coating at SAR 25–60 per m² and bathroom waterproofing at SAR 15–40 per m².

To help the technician, prepare a few details before the visit. Note where you first saw water, whether it appears only after rain or all the time, and whether the problem is on the floor, the walls, or both. Clear access to the affected walls and any stored items so the surfaces can be inspected properly. If the roof is also a concern, mention it, because liquid roof waterproofing (SAR 8–25 per m²) and bitumen membrane (SAR 15–35 per m²) are separate jobs with their own measurements. Clear information at the start means a more accurate quote and a faster, more useful visit.

Some signs can be watched for a few days; others need a technician straight away — the signs list above helps you decide.
