Picture the owner of a busy restaurant in Alkharj who runs a small kitchen and a customer washroom area that sees heavy daily use. Staff are mopping floors several times a day, water is splashing against walls, and the owner is focused on serving guests rather than on what happens behind the tiles. Problems usually show up quietly: a damp patch near a floor drain, a faint smell, or tiles that begin to lift. By the time these signs are noticed, moisture may already have reached the walls behind them.
The centre of Alkharj sits about 439 m above sea level, according to SRTM open elevation data. For a restaurant owner, this means the site should be read as a specific local setting rather than a generic one, and the washroom plan should be checked on that basis. Bathroom waterproofing for this type of property is typically priced at SAR 15–40 per m², which gives owners a clear reference point when comparing the scope of work. Because wet areas in a restaurant are used intensively, owners should not treat waterproofing as an optional extra but as a basic part of keeping the space hygienic and usable.
A practical sequence helps keep the work organised. First, inspect the washroom floor, walls and the joints around the drain, and note any cracks or soft areas. Second, if cracks are present, ask for them to be sealed by crack injection, which is commonly quoted at SAR 40–120 per metre. Third, choose the main waterproofing system for the wet zones; spray foam is often quoted at SAR 20–45 per m², while epoxy coating is quoted at SAR 35–90 per m², so the right choice depends on the surface and how hard the area is used. Fourth, confirm that the finished surface is fully cured before tiling resumes, and keep a simple record of the work for future maintenance.
For restaurants, visits are planned outside service hours and recorded for the premises file.

Short answers for Alkharj
Does an underground tank require waterproofing even if it is new?
Yes, concrete is naturally porous, which can lead to leaks or groundwater seepage. Applying epoxy or cementitious insulation from the start maintains water quality and protects the structure from corrosion.
Do you need to evacuate the building during renovation work?
It depends on the type and scope of the work. Surface work such as plastering and painting usually does not require evacuation, while partial or full evacuation may be advised in cases of structural reinforcement, and the contractor determines this after inspection.
