Why water tank waterproofing differs in Baqiq

The centre of Baqiq sits about 83 m above sea level (SRTM open elevation data). Main roads in or near Baqiq: King Fahd Road.

Team note on Baqiq: 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..

Water tank waterproofing for offices and commercial complexes in Baqiq begins with the basics of the site, and the first thing we check is elevation. The centre of Baqiq sits about 83 m above sea level (SRTM open elevation data), which shapes how water and pressure behave in a building's storage system. Before any coating is discussed, the technician looks at the tank's position, the supply line arrangement, and how the structure is oriented to the local ground, because these factors influence where moisture collects and how the tank walls are loaded over time.

Several things are left to the site visit, because they cannot be judged from a description alone. The technician needs to see the actual tank, its access points, the condition of the internal surfaces, and any signs of seepage, staining, or flaking. The choice between coating methods depends on what is found on the day. For reference only, tank internal coating is priced at SAR 25–60 per m², while epoxy coating is SAR 35–90 per m², and the final figure is set only after the surface area and condition are measured on site. Adjacent areas such as basements, which fall under basement waterproofing at SAR 50–150 per m², are assessed separately if they are connected to the tank room.

Information that helps the technician makes the visit faster and more accurate. Please share the tank's approximate dimensions, its age, what it stores, and any previous repair work or product used. Note any cracks and where they appear, and mention whether crack injection, priced at SAR 40–120 per metre, may already have been attempted. If the tank sits beneath a roof or in a plant area, tell us that too, since liquid roof waterproofing (SAR 8–25 per m²) or a bitumen membrane (SAR 15–35 per m²) may be relevant to the surrounding structure. Clear notes, photos, and access arrangements allow the technician to prepare the right materials and give you a proper assessment for your commercial building.

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

Signs worth paying attention to

The following signs are worth checking before they grow:

• A tank that leaks after testing
• Deposits and flaking inside the tank

Causes we see in the field

• Damaged old coating — we check this before anything else.

• A common cause: construction joints.
