What is specific about Sharurah for water tank waterproofing

Team note on Sharurah: 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 Sharurah sits about 724 m above sea level (SRTM open elevation data).

Main roads in or near Sharurah: King Abdulaziz Road, King Fahd Road.

Water tanks on rest houses and farms in Sharurah are usually the first thing to fail, and the most common problem is slow seepage through hairline cracks and porous concrete walls. Because tanks sit empty for long stretches and are then refilled, the concrete shrinks and cracks, and water finds its way out at the base and along the joints. Owners often notice damp patches on the outside walls or a steady drop in the water level long before any visible leak appears. Early attention keeps the repair small.

Sharurah sits at about 724 m above sea level, which shapes the approach. At this altitude the air is cooler and the sun is strong in the middle of the day, so the concrete goes through heavy daily temperature swings. That movement is why we often recommend crack injection along visible cracks before any surface coating is applied, followed by an internal tank coating that handles the constant cycle of filling and emptying. For tanks that also serve as a reservoir for irrigation or livestock, the coating must be suitable for water that is stored for long periods. For rooftop tanks, a liquid roof waterproofing layer or XPS boards may be added to protect the structure from the sun. Each job is planned around the tank's age, its condition and how it is used, rather than applying one standard treatment everywhere.

Before the visit, ask the service provider a few clear questions. Ask whether they will inspect the tank while it is empty and check for cracks, then explain which treatment they expect to use and why. Ask how the internal coating will be prepared, and whether the surface will be cleaned and dried before any material goes on. Confirm the rates you are quoted, which are usually given per square metre or per metre of crack, so you can compare the scope of work. Finally, ask how long the tank should stay empty after the work is done, and how it should be refilled. A clear answer to each of these points tells you the visit will be useful.

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