Before we start: what we know about Riyadh

Team note on Riyadh: 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 Riyadh sits about 637 m above sea level (SRTM open elevation data).

Main roads in or near Riyadh: King Fahd Road, King Abdullah Road, King Abdullah.

Is your warehouse floor or balcony taking on water, and what will it cost to fix? Riyadh's dry air hides a lot of trouble until the first rains, and many owners only ask this question after cracks or damp patches have spread. The centre of Riyadh sits about 637 m above sea level, so the city's drainage and ground conditions shape how water moves across a site. For warehouse floors and balconies, the cost depends on the method chosen. Epoxy coating runs SAR 35–95 per m², spray foam SAR 20–45 per m², and bitumen membrane SAR 15–35 per m². Liquid roof waterproofing is priced at SAR 10–25 per m², while crack injection is charged at SAR 40–125 per metre. Your inspector will recommend the option that fits your surface and use.

Before any work is quoted, the inspection walks the floor or balcony slowly and maps every crack, joint and low spot where water collects. The inspector checks the condition of the existing coating, looks for hollow areas that sound different underfoot, and notes where drainage points sit relative to the lowest part of the surface. Edges, drain outlets and junctions with walls get particular attention, because that is where leaks usually start. Cracks are measured and marked so that crack injection can be priced accurately. The inspector then compares the findings with the intended use of the space, such as heavy forklift traffic on a warehouse floor or exposure to direct sun on a balcony, and recommends a system that suits both.

To make the visit productive, gather the basic information the inspector will ask for. Have a plan or sketch of the area with drains, columns and any expansion joints marked, and note where you have seen water, stains or peeling previously. Clear the surface of stored goods, debris and loose material so that every part can be examined, and make sure someone with access to the keys or gates is present. If earlier repairs or coatings were applied, bring any records you have so the inspector knows what is underneath. Finally, decide roughly how the space is used day to day, since that will shape the final recommendation.

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