Is your office or commercial complex water tank leaking, and what will it cost to fix? In Muhayil Aseer, the answer depends on the tank's condition and the coating system chosen. The town's centre sits about 455 m above sea level (SRTM open elevation data), and the work is priced by area and by task. Tank internal coating is usually quoted at SAR 25–60 per m², while crack injection is priced per metre at SAR 40–120 per m. Epoxy coating runs SAR 35–90 per m², and spray foam SAR 20–45 per m². Because these rates differ, a clear inspection gives you a figure you can compare against the scope of work.

The inspection starts with a walk around the tank and its surroundings to look for staining, flaking or damp patches. The technician then checks the internal surfaces for cracks, joints and loose coating, marking each defect so it can be measured. Cracks are noted by length, since injection is charged per metre, and the internal floor and walls are measured in square metres for coating. Where roof access is part of the tank system, the liquid roof waterproofing rate of SAR 8–25 per m² and the bitumen membrane rate of SAR 15–35 per m² are considered for the cover. The inspector then recommends a system and a quantity for each area, so the quote reflects what was actually found rather than a guess.

Before the visit, prepare the tank's access details, including keys, ladder or hatch access and any times when the water supply can be shut off. Share records of previous repairs, leak dates and the tank's approximate capacity so the inspector understands its history. Clear the area around the tank and roof so equipment can be placed safely. If the tank serves a basement or bathroom areas, note those too, since basement waterproofing is SAR 50–150 per m² and bathroom waterproofing is SAR 15–40 per m², and you may want them assessed together. Having this information ready helps the inspection finish in one visit and makes the resulting quote easier to approve.

For offices and commercial complexes, work is scheduled to avoid disrupting staff and visitors.
