Before we start: what we know about Rastanura

Team note on Rastanura: 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.. Rastanura is about 0.2 km from the sea coast (OpenStreetMap).

Does a restaurant water tank in Rastanura really need waterproofing, given how close the town sits to the coast? Rastanura lies about 0.2 km from the sea coast (OpenStreetMap), so salty, humid air is a constant presence, and tanks that store water for kitchens, washrooms and cleaning are exposed to it through their walls, lids and fittings. A sealed, protected tank keeps the stored water cleaner and reduces the chance of leaks that can damage the floors and walls below. For a busy restaurant, a tank that fails at the wrong hour means closed kitchens and an emergency call, so protecting it early is usually the sensible choice.

The inspection starts with a walk around the tank and its supporting structure to look for cracks, flaking old coatings, damp patches and signs of efflorescence where salts have come through the surface. The technician checks the tank's internal condition where access allows, marks any cracks that need injecting, and measures the surfaces to be treated so the quotation can be based on real areas rather than guesses. Where the tank sits on a roof or in a basement, the surrounding waterproofing is inspected too, because water that gets past a membrane outside the tank can still find its way in. Each finding is noted so you can see exactly what is recommended and why.

Before the visit, gather any earlier waterproofing records, the age of the tank and any past repair invoices, and note where you have seen damp, stains or unusual water bills. Make sure the tank area is clear and that someone who knows the water supply arrangements can be present. It also helps to tell the inspector how the tank is used, since a kitchen supply and a washroom supply may call for different solutions. With this information ready, the inspection can focus on the real problems and give you a clear, itemised view of the options for your restaurant.

For restaurants, visits are planned outside service hours and recorded for the premises file.
