What is specific about Alzulfi for basement & foundation waterproofing

Team note on Alzulfi: 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 Alzulfi sits about 615 m above sea level (SRTM open elevation data).

Main roads in or near Alzulfi: King Fahd Road, Sheikh Ibn Baz Square, King Salman Road.

Picture the owner of a small serviced-apartment building in Alzulfi, who has noticed a damp patch spreading across the basement wall after a wet spell and wonders whether the hotel guests below ground level are at risk. Their days are filled with check-ins, housekeeping rotas and keeping the rooms ready, so a basement leak feels like one more problem landing on a full plate. What they need is a clear picture of what is causing the damp and what it will cost to fix properly, before any work starts.

The centre of Alzulfi sits about 615 m above sea level, which means the town is set in higher ground rather than a low-lying hollow where water pools. For a property owner this matters because water is more likely to move through the ground and find its way into a basement wall than to sit around the building for long. Basement waterproofing in the area is priced at SAR 50–150 per m², while crack injection is priced at SAR 40–120 per metre, so a damp wall with a visible crack is often the first place to look. Knowing these ranges helps the owner ask sensible questions and compare quotes without guessing.

Start by walking the basement and marking every damp patch, crack and stain with a pencil, noting which faces are wet after rain. Next, have the cracks assessed and injected where they are active, then move to the wall and floor surfaces, choosing between a bitumen membrane at SAR 15–35 per m², epoxy coating at SAR 35–90 per m², or XPS boards at SAR 12–30 per m² depending on the surface and access. Treat any bathrooms in the basement with a separate bathroom waterproofing pass at SAR 15–40 per m², and check the roof with liquid roof waterproofing at SAR 8–25 per m² while the team is on site. Finish by keeping a dated log of each dry-down so the owner can see at a glance whether the basement is holding.

For hotels and serviced apartments, rooms are handled in batches to keep units available.
