What is specific about Dhahran for bathroom waterproofing

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

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

Do you need to know how far your building sits from the sea before booking bathroom waterproofing in Dhahran? For companies signing an annual contract, the location matters because the centre of Dhahran sits about 16 m above sea level, and the city is about 5.9 km from the sea coast. Those facts help explain why a single fixed rate rarely suits every site, and why each bathroom on your portfolio should be checked on its own before any work is agreed. Bathroom waterproofing in this range is priced at SAR 15–40 per m², and the final figure depends on the area surveyed and the condition of the surfaces.

The inspection follows a clear order. First, the surveyor walks each bathroom and notes the floor area, the wall height, and any existing coating that may be peeling or lifting. Second, they check the joints around the shower tray, the drain, and the wall-to-floor line, since these are the usual points where water finds a way through. Third, any cracks are recorded, and where a crack runs through the substrate, crack injection is priced separately at SAR 40–120 per metre. Where a bathroom sits above another living space, the surveyor also notes whether a membrane, a spray foam layer, or an epoxy coating would suit the surface better, using the rates for each option as a reference. The result is a written schedule for each unit, so your facilities team can compare sites side by side across the year.

Before the visit, prepare a list of every bathroom covered by the contract, with its floor and unit number, and note any leaks or stains you have already seen. Make sure access is arranged for each room, including keys for locked units and a time when occupants are informed. Keep any earlier repair records or drawings, as they help the surveyor understand what has already been done. If your buildings have basements or water tanks, list them too, since those areas are priced on their own rates and can be included in the same annual agreement. With this information ready, the visit runs faster and the schedule you receive will be complete and easy to act on.

For companies, an annual contract sets the scope, the visit schedule and the reports in writing.
