Wall damp treatment in Riyadh: the local context

Team note on Riyadh: 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 Riyadh sits about 637 m above sea level (SRTM open elevation data).

Main roads in or near Riyadh: King Fahd Road, King Abdullah Road, King Abdullah.

Riyadh's centre sits about 637 m above sea level (SRTM open elevation data), so the first checks for a damp wall in a villa are about where the water is coming from rather than what the altitude does to the building. Start at the base of the wall and the junction with the ground, because rising damp and ground moisture are the most common sources in villas here. Look at the ground level outside the wall, whether soil banks against the foundation, and whether any downpipe or irrigation line discharges close to the structure. Check the rooms below ground first, since basement waterproofing is priced separately at SAR 55–160 per m², which tells you that a basement wall is a different scope from a ground-floor wall. Next, inspect wet rooms, as bathroom waterproofing is a distinct item at SAR 15–40 per m² and leaks there often show up as damp on the adjoining wall.

The site visit settles the questions that no description can answer. The technician has to measure the moisture pattern, find the exact point where a crack runs through the wall, and judge whether the crack is active or old. Crack injection is charged per metre, at SAR 40–125 per m, so the length and path of each crack must be recorded on site. Roof and parapet leaks are assessed by walking the surface, since liquid roof waterproofing at SAR 10–25 per m² and bitumen membrane at SAR 15–35 per m² are chosen only after the substrate condition is known. Whether a water tank is in the damp chain, and whether its interior needs tank internal coating at SAR 25–65 per m², is also decided in person. The choice between epoxy coating at SAR 35–95 per m², spray foam at SAR 20–45 per m² and XPS boards at SAR 15–30 per m² depends on the wall's finish, its exposure and how much access there is to the inner face.

To help the technician arrive prepared, the homeowner should note when the damp first appeared and whether it rises after rain, after irrigation or only in dry periods. Mention any previous repairs, paint blistering, salt crystals on the surface or a smell in closed rooms. Clear furniture and stored items away from the affected wall, and make sure the basement, bathrooms and roof are accessible. Photos taken over several days help show the pattern, and a rough sketch of the villa with the damp areas marked speeds up the measurement and keeps the scope of work accurate.

In a villa, tanks, the roof and the yard lines are usually yours to look after, so it helps to know where the main valve and tank hatches are.
