Team note on Alnuayriyah: 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..

Before any product is chosen for floors or balconies in Alnuayriyah, the first thing checked is the ground level, because the centre of Alnuayriyah sits about 49 m above sea level (SRTM open elevation data). That figure tells the technician the area is not a low-lying basin where water collects after rain, so the drainage path is usually the question to settle early. The visit starts by tracing where water currently runs off the slab or balcony, whether the outlets are blocked, and whether the falls toward them are right. Ponding on a balcony that looks sound can be a sign the surface needs regrading before any membrane goes on.

Several points are left to the site visit, because they depend on what the technician finds on the day. The extent and depth of any cracking is measured and mapped; a crack that is open and moving calls for crack injection, which is priced at SAR 40–120 per metre, while a hairline crack on a stable surface may need nothing more than cleaning and sealing. The condition of the substrate, whether it is sound, dusty, oily or contaminated with old coatings, decides whether the surface has to be ground or blasted first. The choice between liquid roof waterproofing at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², spray foam at SAR 20–45 per m², or epoxy coating at SAR 35–90 per m² is made on site once the surface and the use of the area are clear. Any figure given here is a general range, and the final scope always depends on the inspection.

To help the technician, it is useful to have a few things ready before the visit. Note where leaks have appeared, whether they follow rain, and whether they show up inside a room below the balcony. Say what the balcony or floor is used for, since a space that takes foot traffic, plant pots or a washing area needs a different finish from one used only for sitting. Mention any earlier repairs, previous coatings or tiles that were laid on top, and whether the slab is accessible from below. Clear access to the area and a note of the main water outlets speed up the inspection, and a short record of the problem spots, with photographs if possible, lets the technician plan the work and explain the options without guesswork.

The aim is to locate the cause with instruments first, so any opening is limited to one point.
