Why epoxy coating & waterproofing differs in Najran

Team note on Najran: 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.. Main roads in or near Najran: Al Jarba Street.

The centre of Najran sits about 1309 m above sea level (SRTM open elevation data).

Najran sits at roughly 1309 m above sea level, which gives the city a markedly different climate from the coastal cities of Saudi Arabia. The elevation means the air is generally cooler and drier than in the lowlands, but the area still experiences heavy seasonal rain when storms arrive, and that water tends to run quickly across rooftops, courtyards and drainage channels. For restaurant owners, this combination of altitude and occasional intense rainfall makes the building envelope a constant point of concern.

Because of this, we link each part of our service to a practical effect. Liquid roof waterproofing, priced at SAR 8–25 per m², is well suited to flat roofs that collect rainwater, and it helps keep kitchen ceilings and dining areas dry during storms. Epoxy coating, at SAR 35–90 per m², gives kitchen and prep floors a sealed, non-porous surface that is easier to clean after heavy use and resists oil and grease. Where a restaurant has a basement store or cold room, basement waterproofing at SAR 50–150 per m² protects stock and equipment from seepage. Crack injection, at SAR 40–120 per metre, seals hairline gaps in walls and slabs before they let moisture through, which is far cheaper than repairing damage after it appears. Bathroom waterproofing, at SAR 15–40 per m², protects guest and staff washrooms, where constant wet cleaning can otherwise lead to leaks into the floor below.

Owners in the city also tend to avoid several common mistakes. The first is treating the roof as an afterthought, when rainwater on a restaurant roof can quickly reach the ceiling above the kitchen. The second is coating a floor or wall without first repairing cracks, since the coating will simply trap moisture beneath it. The third is ignoring the tank and water storage area, where internal coating at SAR 25–60 per m² keeps the water clean and the structure sound. Finally, many owners delay work until a leak is visible, when a planned inspection would have prevented the disruption and cost of emergency repairs during busy service hours.

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