Before we start: what we know about Sabya

Sabya is about 16.7 km from the sea coast (OpenStreetMap). The centre of Sabya sits about 40 m above sea level (SRTM open elevation data).

Main roads in or near Sabya: King Fahd Road, King Abdulaziz Road, King Abdullah bin Abdulaziz Road. Team note on Sabya: 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 in Sabya starts with the location itself. The centre of Sabya sits about 40 m above sea level according to SRTM open elevation data, and the town is about 16.7 km from the sea coast, so the technician checks the tank's exposure to the local climate and groundwater conditions before choosing a system. Sabya's position inland means the team looks first at the tank's internal condition and how water has been held over time, rather than assuming salt-laden air is the main concern.

Several things are left to the site visit, because they cannot be known from a distance. The technician inspects the tank walls and floor for cracks, flaking, and old coating, and decides whether the tank needs a full internal coating or targeted repair. Access, the tank's size, and whether the tank is still in use during the work all shape the method. Where a crack is found, the technician measures its length and decides between crack injection and surface treatment. The actual choice of system and the final quotation depend on what is seen on the day.

To help the technician prepare, residents and property managers should note the tank's material, its approximate age, and any past leaks or repairs, along with the date water was last drained. Clear access to the tank lid and the surrounding area saves time on arrival. Information about whether the tank holds potable water matters, since it affects which coatings can be used. Pricing for internal tank coating typically falls in the range of SAR 25–60 per m², while crack injection is typically SAR 40–120 per metre, so measuring the tank's inside surface area and any visible cracks in advance gives a more useful starting point for the site visit.

For a whole building, a survey of the shared systems comes before unit-by-unit work.
