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

The centre of Sharurah sits about 724 m above sea level (SRTM open elevation data).

The first thing checked on a water tank job in Sharurah is the site's altitude, because it shapes how the tank is fed and how it holds water. The centre of Sharurah sits about 724 m above sea level (SRTM open elevation data), which means that a tank on a roof or in a shaft is working against gravity from a fairly high base. Before anyone looks at the coating, the technician notes how the building receives its supply, where the tank sits, and whether the overflow and inlet lines are in good order. A leak that looks minor can turn into a larger problem when pressure and storage levels change, so this early check is about understanding the whole system rather than only the surface.

Several things are left to the site visit, because they cannot be judged from a distance. The technician needs to see the actual condition of the tank walls and floor, any cracks or flaking, the state of the lid and vents, and whether damp is coming through from the building structure around it. Access matters too: a tank inside a small utility room is treated differently from one reached by a roof hatch. The quoted cost depends on what the inspection finds, since internal coating, crack repair and roof work are priced on different bases. Price ranges for tank internal coating run from SAR 25 to SAR 60 per m², while crack injection is charged per metre at SAR 40 to SAR 120 per m, so the measured extent of the damage decides where in each range the final figure lands. Nothing is finalised until the surfaces have been measured on site.

Information that helps the technician is simple to gather before the visit. Tell us roughly how old the tank is, what it is made from, whether it has been coated before and with what, and whether water has been tasting or looking unusual. Photographs of the tank interior, the roof area and any visible cracks are useful, and it helps to know the approximate size of the tank and the roof section it sits on. Note whether the building has a basement or bathrooms nearby that may share the same damp source. With these details in hand, the technician can arrive ready to measure properly and explain the options clearly.

In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.
