Bathroom waterproofing in Dhahran: the local context

Team note on Dhahran: 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.. The centre of Dhahran sits about 16 m above sea level (SRTM open elevation data).

Dhahran is about 5.9 km from the sea coast (OpenStreetMap).

Bathroom waterproofing in clinics is most often needed because floors and wall joints fail under constant wet cleaning, and water seeps through to the rooms below. In a clinic, a leak is not only a cosmetic problem. It can interrupt patient care, damage equipment and create hygiene risks, so the work needs to be done carefully and with minimal disruption to the day's schedule. Typical bathroom waterproofing for this type of property is priced at SAR 15–40 per m², and the price depends on the condition of the existing surface and the number of wet areas being treated.

Dhahran's location shapes how we approach this work. The centre of the city sits about 16 m above sea level, and it is about 5.9 km from the sea coast. Those facts mean that the ground is not at sea level, but the area is still close enough to the coast that moisture and salt-laden air are part of daily conditions. For clinic bathrooms, we therefore pay close attention to how the membrane meets walls, pipes and floor drains, and to how well surfaces dry before coating. Where a clinic has a basement or a tank on the property, the same attention applies, with epoxy coating at SAR 35–90 per m² or tank internal coating at SAR 25–60 per m² as the relevant options. Crack injection, priced at SAR 40–120 per metre, is often used where hairline cracks open up at junctions in the floor.

Before the visit, it helps to have a few details ready. Tell us which rooms are affected, which floors are above or below the leak, and how long the bathroom has been in use since its last waterproofing. Mention whether the clinic can close the room for a period, and whether work must be carried out outside clinic hours. Share any photos of staining, peeling tiles or cracks, and let us know if the leak appears only after heavy cleaning or during rain. These answers let the visit focus on the right problem and give the clinic a clear, practical quote.

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