What is specific about Abu Arish for floor & balcony 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..

At schools in Abu Arish, the most common waterproofing problem is water entering through flat roofs and the edges of balconies and walkways, where ponding and cracked screeds let rain soak into the slab below. Classrooms and corridors beneath these areas show stains, peeling paint and damp patches, and in older buildings the leak often runs along the joints where the roof meets the parapet. Because schools have large flat roof areas and long covered walkways, small defects can spread quickly across a whole block if they are not dealt with early.

Abu Arish sits about 67 m above sea level, so the local approach focuses on sealing and draining surfaces rather than managing groundwater pressure, which is the main concern in low-lying sites. A liquid roof waterproofing system, priced at SAR 8–25 per m², is often suitable for large school roofs because it can be applied over the existing surface and creates a seamless layer that handles the many small joints and upstands. For balcony and walkway floors, a bitumen membrane at SAR 15–35 per m² or an epoxy coating at SAR 35–90 per m² can be chosen depending on how much foot traffic the area receives. Where cracks are visible, crack injection at SAR 40–120 per metre is usually carried out before any surface layer is applied, so the repair is not hidden under new material.

Before the visit, ask the provider to confirm which areas are roof, which are balcony or walkway floor, and where any ponding or cracking has already been noticed. Ask whether the surfaces will need to be cleared during school hours, and how work will be scheduled around classes and assemblies. Request a written breakdown that separates each surface type and its per-m² or per-metre rate, so you can compare the options clearly. Finally, ask how the surface will be drained and protected once the work is complete, since standing water is the most likely cause of the problem to return.

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