Is your restaurant's balcony or floor slab letting water through, and how do you know what it will cost to fix? In Sharurah, the centre of town sits about 724 m above sea level (SRTM open elevation data), and that setting shapes how a floor or balcony should be protected. The price of the work depends on the method and the area involved. Liquid roof waterproofing typically runs SAR 8–25 per m², bitumen membrane SAR 15–35 per m², spray foam SAR 20–45 per m², and epoxy coating SAR 35–90 per m². For a restaurant, these ranges help you compare options against the size of the balcony or kitchen floor before any work starts.

Before any material is chosen, the inspection begins with the surface itself. The team checks for cracks, and where a crack is found, crack injection is priced at SAR 40–120 per metre, which is often the first step before a coating is laid. The surface is then examined for ponding, staining on ceilings below the balcony, and areas where the finish has lifted or worn through under foot traffic. Where a drainage outlet or joint looks weak, it is noted for attention. Because restaurant floors take heavy wear from chairs, spills and cleaning, the inspection also records how the surface is used day to day, so the recommended system can match that demand rather than a generic specification.

Preparation makes the visit faster and the quote more accurate. Gather the floor plan or a rough sketch with the balcony and floor dimensions in square metres, so the area can be measured against the per-m² rates above. Note any past leaks, repairs or coatings you already know about, and mention whether the space is a kitchen, dining area or outdoor seating, since this affects the choice of finish. Clear access to the balcony or floor edge, and tell the staff which hours are quiet enough for work, so the restaurant can keep trading. Having these details ready lets the inspection focus on the surface rather than on questions, and it gives you a clear basis for comparing the options.

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