Before we start: what we know about Alnuayriyah

Team note on Alnuayriyah: 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 Alnuayriyah sits about 49 m above sea level (SRTM open elevation data).

Is a water tank on a rest house or farm in Alnuayriyah worth waterproofing, and what will it cost? The centre of Alnuayriyah sits about 49 m above sea level, and the tank coating you choose should be priced against the work involved. For internal tank work, tank internal coating runs SAR 25–60 per m², and epoxy coating for surfaces that need a harder finish runs SAR 35–90 per m². If the tank has visible cracks, crack injection is charged per metre at SAR 40–120 per m, so a short inspection can tell you which line item applies before any material is ordered.

On the visit, the technician will start by walking the full tank and the roof area above it, marking every crack and joint that shows moisture or staining. Cracks are measured in metres so the injection quote matches the actual length, and the internal surfaces are checked for flaking or loose old coating. The roof is checked as well, because leaks often start there rather than inside the tank. Where the roof is exposed, liquid roof waterproofing at SAR 8–25 per m² or a bitumen membrane at SAR 15–35 per m² may be recommended, and the technician will note the measured area of each. Spray foam at SAR 20–45 per m² and XPS boards at SAR 12–30 per m² may also be discussed for insulation or additional protection, depending on what the surface can take. Each option is listed with its own per-m² rate so you can compare them side by side.

Before the visit, clear access to the tank hatch and the roof, and make sure the water level can be lowered or the tank emptied on the day, because surfaces must be dry and visible to be assessed properly. Have any previous repair records or invoices ready, and note where you have seen damp patches, stains or water on the walls. Tell the technician whether the tank holds drinking water, since that affects which coating is suitable. Measure the approximate tank dimensions and roof area if you can, so the estimate starts from real figures rather than guesses. With those details in hand, the inspection can move straight to a clear list of work and cost for your rest house or farm.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.
