Before we start: what we know about Sharurah

Team note on Sharurah: 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 Sharurah sits about 724 m above sea level (SRTM open elevation data).

Main roads in or near Sharurah: King Abdulaziz Road, King Fahd Road.

Before anything else, a technician in Sharurah checks the ground and the water it carries, because the town sits about 724 m above sea level (SRTM open elevation data), which shapes how rain runs off and where it collects around a warehouse. The first check is the slope of the land toward the building, the condition of any existing drainage channels, and whether the basement or lowest slab is taking in water at a crack or joint. Those points decide whether the job is a surface fix or a structural one, and they come before any material is chosen.

Several items are left to the site visit, because they cannot be judged from a desk. These include the actual depth and length of cracks, which sets whether crack injection is needed and is priced per metre at SAR 40–120 per m; the area of basement wall or floor that needs basement waterproofing at SAR 50–150 per m²; and whether the roof needs liquid roof waterproofing at SAR 8–25 per m² or a bitumen membrane at SAR 15–35 per m². The technician also confirms whether a water tank is involved, since tank internal coating runs SAR 25–60 per m², and whether insulation boards such as XPS (SAR 12–30 per m²) or spray foam (SAR 20–45 per m²) suit the walls. Epoxy coating, at SAR 35–90 per m², is weighed against these options only after the surface has been inspected.

To help the technician, the client should have ready the warehouse floor plan with measured wall and slab areas, any previous leak records or repair notes, and the location of drains, sumps and tanks. Noting which walls face the slope and where water has been seen after rain makes the visit quicker. Access to the basement, roof hatches and loading areas should be arranged in advance. This information lets the technician measure the areas that are priced per square metre and per metre, and it gives a clear picture of what the building needs in Sharurah.

For warehouses, work is phased around operations and stored goods.
