What is specific about Alnuayriyah for basement & foundation waterproofing

Team note on Alnuayriyah: 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 Alnuayriyah sits about 49 m above sea level (SRTM open elevation data).

Basement and foundation leaks in hotels and serviced apartments usually show up as damp patches on lower walls, efflorescence on concrete, and water pooling near the slab edge after heavy rain. Because these buildings rely on their lower floors for plant rooms, storage and guest-facing amenities, a small leak can quickly disrupt operations and guest comfort. Cracks in the foundation wall and failed joints between the slab and wall are the most frequent entry points, and they tend to widen over time as the structure settles.

Alnuayriyah sits about 49 m above sea level, which shapes how we approach these jobs. Because the centre is on a modest rise rather than a low-lying flood plain, the priority is usually managing groundwater pressure and surface runoff that moves toward the building rather than standing water. Crack injection, typically priced at SAR 40–120 per metre, is often the first step where a clear crack line is found, while basement waterproofing at SAR 50–150 per m² is considered when the whole wall needs protection. Where the basement is used for water storage or plant, tank internal coating at SAR 25–60 per m² and epoxy coating at SAR 35–90 per m² are also worth discussing, since they protect against moisture that migrates through the structure.

Before the visit, ask the provider which area of the basement or foundation they expect to cover, and whether they will inspect the wall and slab edges during dry and wet conditions. Ask how they plan to handle cracks, joints and any bathroom or plant-room sections, and which materials they recommend, such as bitumen membrane at SAR 15–35 per m² or XPS boards at SAR 12–30 per m², and why. Request a written scope showing quantities and unit rates in SAR, and confirm how long guests or operations may be affected. Clear answers to these questions make it easier to compare proposals and to plan the work around your property's occupancy.

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