Before we start: what we know about Abu Arish

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 centre of Abu Arish sits about 67 m above sea level (SRTM open elevation data).

Before any quote is written for a basement or foundation job in Abu Arish, the first thing to check is the ground itself. The centre of Abu Arish sits about 67 m above sea level, according to SRTM open elevation data, so the site is not a low-lying basin where surface water collects. That matters because it shifts the first question from "where will the water pool?" to "where is it coming from?" Technicians should look for the source of moisture, whether it is rising from the slab, seeping through the walls, or entering through cracks, before deciding on a method. The price bands given for this work, basement waterproofing at SAR 50–150 per m² and crack injection at SAR 40–120 per metre, show how different the solutions can be, so an accurate diagnosis is the foundation of any useful estimate.

Several points are left to the site visit, because they cannot be settled from a desk. The technician needs to measure the actual wall and slab areas, count the linear metres of cracks, and judge how far the membrane or coating can be taken up the wall before it meets the ground line. The choice between epoxy coating at SAR 35–90 per m², spray foam at SAR 20–45 per m², and XPS boards at SAR 12–30 per m² depends on the condition of the substrate, access, and whether the basement will be used as a living or storage space. Tank internal coating at SAR 25–60 per m² or liquid roof waterproofing at SAR 8–25 per m² are separate scopes that should be confirmed on site rather than assumed from the main job.

To help the technician, the office should prepare a short brief before the visit: the building's use, any previous leak repairs, and photographs of visible cracks or staining. Note whether the basement is wet all year or only after rain, since this changes the recommended approach. Bring a simple drawing with dimensions so areas can be calculated against the per-m² rates, and mark crack lengths in metres so they can be priced against the crack injection rate. Recording these details in advance means the site visit can focus on verification and measurement, and the resulting quote will reflect the real conditions at the property.

For companies, an annual contract sets the scope, the visit schedule and the reports in writing.
