Why bathroom waterproofing differs in Sharurah

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.

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..

Bathroom waterproofing in restaurants in Sharurah most often fails at the floor-to-wall junction and around floor drains, where standing water and frequent mopping slowly lift tiles and let moisture into the screed below. In a commercial kitchen-adjacent washroom or staff bathroom, the traffic and cleaning chemicals wear through surfaces far faster than in a home, so a tile reset that looks like a small job often hides a damp slab underneath. Our guidance starts by checking these junctions and drains before anything else is quoted.

Sharurah sits at about 724 m above sea level, which means the town is not in the low, humid coastal belt, but it still sees strong day-to-night temperature swings and dry, dusty conditions that dry out and crack sealants and screeds over time. That altitude and climate shape the approach: flexible coatings that tolerate movement tend to suit these spaces better than rigid finishes that crack when the substrate shifts. For bathroom work the usual range is SAR 15–40 per m², and where the floor needs a seamless, easy-clean surface, epoxy coating at SAR 35–90 per m² is often considered. Where cracks appear in the wall or slab, crack injection at SAR 40–120 per metre may be needed before any coating is applied.

Before the visit, ask the provider to confirm which surfaces they will inspect, including the drain outlet, the wall junction and any visible cracks, and whether they will test for moisture before quoting. Ask what material they propose and why it suits a floor that is cleaned daily with water and detergent, and whether the quote is per m² and covers preparation as well as the coating itself. Confirm how long the restaurant can keep the area out of use and whether the work can be scheduled around service hours. A clear written scope tied to the measured area will make the final cost easier to compare.

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