What is specific about Abu Arish for water tank waterproofing

The centre of Abu Arish sits about 67 m above sea level (SRTM open elevation data). Team note on Abu Arish: 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 first thing checked for a water tank in Abu Arish is the tank itself and its site, because the centre of Abu Arish sits about 67 m above sea level (SRTM open elevation data). That height matters for how water reaches rooftop and elevated tanks, so the technician looks at the tank's position, its supply connections and any signs of leakage at the joints before anything else. Cracks, flaking coatings and damp patches on the walls and base are noted first, since they show where water is already getting through and where repair work will need to start.

Some decisions depend on what is found on the day and are left to the site visit. The technician measures the tank's internal surface area, checks whether the existing lining can be prepared or must be removed, and decides between a tank internal coating and other options. Typical ranges for tank internal coating run from SAR 25 to SAR 60 per m², while crack injection is priced from SAR 40 to SAR 120 per metre. Where the problem is in the roof or the basement instead, the choice between liquid roof waterproofing at SAR 8–25 per m², a bitumen membrane at SAR 15–35 per m² or XPS boards at SAR 12–30 per m² is also made on site. Epoxy coating (SAR 35–90 per m²) and spray foam (SAR 20–45 per m²) are assessed the same way, once the surface condition is clear.

To help the technician, residents and property managers should have ready the tank's size and access points, the age of the building, any previous repair records and a note of when leaks were first noticed and where. Photographs of the damp areas are useful, and clear access to the roof, basement and tank room saves time. Knowing whether the tank is roof-mounted or ground-level, and whether it has been drained recently, also helps the technician plan the work and give a realistic estimate for the job.

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