Team note on Qatif: 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..

Does a basement in Qatif really need waterproofing, given that the city is not far from the coast? The facts answer this directly. The centre of Qatif sits about 5 m above sea level, according to SRTM open elevation data, and the city is about 2.5 km from the sea coast, based on OpenStreetMap. That combination of low elevation and nearness to the shoreline means ground water and moisture can be a real concern for below-ground rooms, so a property owner should treat basement protection as a serious question rather than an afterthought.

The inspection process starts with identifying where water could enter and what type of protection suits each area. Basement waterproofing is priced at SAR 50–150 per m², and bitumen membrane at SAR 15–35 per m², while epoxy coating ranges from SAR 35–90 per m² and spray foam from SAR 20–45 per m². Cracks are often the first thing examined, and crack injection is quoted at SAR 40–120 per metre. Wet areas such as bathrooms fall under a separate rate of SAR 15–40 per m², and roofs can be assessed for liquid roof waterproofing at SAR 8–25 per m². Water tanks, if present, may need tank internal coating at SAR 25–60 per m². Where insulation is part of the plan, XPS boards are listed at SAR 12–30 per m². The inspector uses these categories to match the right method to each surface.

Before the visit, prepare a clear picture of the space so the inspection is useful. Note which rooms sit below ground, where you have seen damp patches, staining, peeling paint or cracks, and whether any leaks appear after rain. Gather any previous repair records and make the water tank, bathrooms and roof accessible. Measure or estimate the areas involved, since most rates are set per square metre or per metre of crack, which makes the scope easier to compare. Having these details ready lets the team in Qatif focus on the problem areas and give you a clearer, more practical plan.
