Before we start: what we know about Yanbu

Main roads in or near Yanbu: King Abdulaziz Road, Umluj Road, Al Hanan Street. Team note on Yanbu: 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..

Yanbu is about 1.2 km from the sea coast (OpenStreetMap). The centre of Yanbu sits about 6 m above sea level (SRTM open elevation data).

Restaurant floors and balconies in Yanbu take a lot of punishment. Kitchen floors get grease, hot water, and constant foot traffic, while outdoor balconies face the sun and wind. The most common problem we see is water finding its way through a worn or cracked surface and reaching the floor below, which can stain ceilings, damage stored goods, and cause costly disruption to trading. Many owners only notice the problem once a patch of damp appears, by which point the water has already travelled some distance.

The local setting shapes how we approach the job. The centre of Yanbu sits about 6 m above sea level, and the city is about 1.2 km from the sea coast. That combination means salt-laden air and moisture are present in the surrounding environment, so the materials we choose must hold up well against both water and salt exposure. For restaurant floors that need to stand up to cleaning chemicals and heavy use, an epoxy coating, typically SAR 35–90 per m², can provide a tough, seamless finish. For balconies and roofs exposed to open sky, a liquid roof waterproofing system at SAR 8–25 per m² or a bitumen membrane at SAR 15–35 per m² are often considered, depending on the surface condition. Where cracks have already formed, crack injection at SAR 40–120 per metre is usually part of the preparation.

Before the visit, it helps to have a few details ready. Tell us the exact area of the floor or balcony, whether it is indoors or open to the weather, and what the surface is made of. Describe where you have seen water or damp, and whether any cracks are visible. Let us know how the space is used, including whether grease, hot water, or heavy equipment are involved, and when the business can afford to have the area out of use. With this information, we can arrange a visit that focuses on the right solution for your restaurant in Yanbu.

For restaurants, visits are planned outside service hours and recorded for the premises file.
