What is specific about Abu Arish for basement & foundation 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..

Is a school basement in Abu Arish at risk of water damage, and how do you know? The centre of Abu Arish sits about 67 m above sea level (SRTM open elevation data), and that elevation shapes how water moves around a building, though local ground conditions still decide whether a basement stays dry. Schools with below-grade rooms, storage areas or plant rooms should not assume the site is safe simply because it is inland. A proper assessment looks at the walls, floor slab and joints to find where moisture is entering before any work is priced.

The inspection for a school basement usually follows a clear sequence. The surveyor first walks the full perimeter and the interior, noting damp patches, efflorescence, stains and any visible cracks, then measures the length and wall area that need treatment. Cracks are mapped individually, since crack injection is priced per metre (SAR 40–120 per m) and is quoted separately from surface work. Next, the surveyor compares the options that suit the findings: basement waterproofing is quoted at SAR 50–150 per m², epoxy coating at SAR 35–90 per m², spray foam at SAR 20–45 per m², and bitumen membrane at SAR 15–35 per m². Where a water storage tank sits in the building, tank internal coating at SAR 25–60 per m² is assessed on its own. The report then recommends a method based on what was actually found, not a single product for every wall.

To make the visit productive, school administrators should prepare a few things in advance. Gather existing drawings, any previous repair records and a note of when leaks were first noticed and how they change after rain. Clear access to the basement, plant rooms and the tank area, and identify who will sign off on the work so decisions are not delayed. Ask the facilities team to note which rooms are in use during term time, because the surveyor will need to plan around teaching schedules. Having this information ready helps the inspection cover the right areas and keeps the quote tied to the real condition of the building.

For schools, the larger jobs are planned for weekends and holidays.
