Bathroom waterproofing for clinics in Ghrnata, Riyadh, most often starts with water tracking through floor and wall joints into the rooms below or the adjoining corridor. In clinics the problem is harder to spot than in a home, because wet areas are used all day, cleaning is frequent and staff may not report a small stain at once. The usual weak points are the floor-to-wall junction, the drain surround and the area where pipes pass through the slab. Our approach for this type of job is to check these joints first, since a sound membrane at the edges is what keeps water out over time. Bathroom waterproofing is priced at SAR 15–40 per m², and where cracks are present, crack injection at SAR 40–125 per metre is often needed before the membrane is applied.

Ghrnata is mainly villas, so the buildings we work on here are usually of a similar age and construction to residential homes rather than purpose-built medical blocks. That matters because clinic fit-outs in villa conversions often add heavier fixtures, more frequent wet cleaning and drainage layouts that were not designed for commercial use. The centre of Ghrnata sits about 617 m above sea level, and it lies about 11 km from the centre of Riyadh, within an approximate radius of 2.8 km. Our recommendations take into account these local conditions, including how the building was originally planned and how the clinic will use each room. Where a wet room sits above a basement or a tank, the scope and cost can rise, with basement waterproofing at SAR 55–160 per m² and tank internal coating at SAR 25–65 per m² as separate items.

Before the visit, ask the clinic manager or property owner for the list of rooms with water use, the age of the existing tiling and any history of leaks or staining. Ask whether the rooms below or next to the bathroom are used for patient care, so that work can be planned around opening hours. Also ask whether there are cracks in the slab or walls and whether the room has been re-tiled before. Having this information ready helps us give a clear scope and a realistic estimate on the first visit.

For clinics, work is scheduled around patient hours and kept to the areas that need it.
