What is specific about Duba for basement & foundation waterproofing

Team note on Duba: 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.. Duba is about 0.2 km from the sea coast (OpenStreetMap).

The centre of Duba sits about 10 m above sea level (SRTM open elevation data).

Can a hotel or serviced apartment basement in Duba be waterproofed without flooding the guest areas above? That is the question most property owners ask first, and the answer starts with the site itself. The centre of Duba sits about 10 m above sea level, and the town is about 0.2 km from the sea coast. Those two facts mean that a basement here is close to the water table and exposed to salt-laden air, so moisture can build up from below and from the sides at the same time. Our basement and foundation waterproofing work is planned around that reality, rather than treating the job as a simple surface coat.

Our inspection begins with a walk-through of the basement, the foundation walls and the joints where the structure meets the ground. We look for active cracks, damp patches, efflorescence and signs of past repairs, and we note where water enters or runs along the surface. Where cracks are present, we measure them and decide whether crack injection, at SAR 40–120 per metre, is the right step before any membrane or coating goes on. We then compare the wall and floor areas against the options available, including basement waterproofing at SAR 50–150 per m², epoxy coating at SAR 35–90 per m², spray foam at SAR 20–45 per m², bitumen membrane at SAR 15–35 per m² and XPS boards at SAR 12–30 per m². Each choice is explained in plain terms so the owner can see why one method suits a particular wall and another suits a different area.

Before the visit, it helps to prepare a few things so the inspection is efficient and the findings are accurate. Gather any previous waterproofing records, repair invoices and drawings of the building, and note when damp was first noticed and whether it rises after rain or stays constant. Clear access to the basement walls, the lift pit or sump if there is one, and any service rooms, so the team can inspect the full perimeter. If the hotel has a water tank in the basement or on the roof, make sure its location is known, since tank internal coating at SAR 25–60 per m² and liquid roof waterproofing at SAR 8–25 per m² may also be relevant. With this information ready, the inspection can move directly to a clear, written scope of work.

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