Wall damp treatment in Alkharj: the local context

Main roads in or near Alkharj: King Abdullah Road. The centre of Alkharj sits about 439 m above sea level (SRTM open elevation data).

Team note on Alkharj: 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 a technician checks in Alkharj is the lie of the land, because it shapes how water behaves around a building. The centre of Alkharj sits about 439 m above sea level according to SRTM open elevation data, and that elevation helps explain why a wall can look dry in summer yet show rising stains after a wet spell. Before buying or accepting a handover, ask the seller or landlord where the damp appears, whether it is worst at ground level, and whether it follows a pattern such as a single corner or the whole base of one wall. These clues matter more than any headline figure, so write them down and keep them for the technician.

Several decisions are left to the site visit, because they cannot be judged from a description alone. The technician will look at whether the damp comes from rising moisture, leaking pipes, a failed bathroom seal, or water entering through a roof. They will decide which method suits each area: a basement may need basement waterproofing priced at SAR 50–150 per m², a bathroom may need bathroom waterproofing at SAR 15–40 per m², and a cracked section may need crack injection at SAR 40–120 per metre. They will also check whether a tank needs tank internal coating at SAR 25–60 per m², and whether the roof needs liquid roof waterproofing at SAR 8–25 per m² or a bitumen membrane at SAR 15–35 per m². Other options, such as epoxy coating at SAR 35–90 per m², spray foam at SAR 20–45 per m², or XPS boards at SAR 12–30 per m², are chosen only once the source is clear. Every figure here is an indicative range, and the final quote depends on the inspection.

To help the technician, prepare a short note before the visit. Record the rooms affected, the wall orientation, any visible cracks and their length, and when the damp is most noticeable. Mention recent repairs, previous paint or plaster work, and any past leaks in the flat above. Share photographs taken during rain if you have them. Bring the plan of the property, and tell the technician which areas you plan to use, since that affects the choice of coating. Clear, specific information lets the visit focus on the cause rather than on guesswork, and it gives you a clearer basis for comparing quotes before you commit.

Before buying or taking over a property, an inspection gives you findings in writing before you sign.
