Wall damp treatment in Khobar: the local context

Team note on Khobar: 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 Khobar sits about 9 m above sea level (SRTM open elevation data).

Khobar is about 1.8 km from the sea coast (OpenStreetMap).

Wall damp in Khobar starts with location. The centre of Khobar sits about 9 m above sea level, and the city is about 1.8 km from the sea coast. Because of that, a technician will look first at whether moisture is rising from the ground, coming through the outside walls, or carrying in salt-laden air from the coast. A stain that only appears on the wall nearest the sea, or a white crust that returns after being wiped off, points toward salt and air movement rather than a single leak. Checking these patterns first helps decide whether the wall needs surface treatment, an internal barrier, or repair of a source of water entering from outside.

Several things cannot be settled from a description alone and are left for the site visit. The technician will press on the wall, check the floor level against the outside ground, look at the room directly above and below, and note whether the bathroom or kitchen sits against the affected wall. Moisture readings are taken in several spots, not one, and the age and type of plaster matter. The site visit also confirms the scope and the area in square metres or metres of crack, since the work is quoted per unit. Prices for the common approaches are SAR 15–40 per m² for bathroom waterproofing, SAR 35–90 per m² for epoxy coating, SAR 20–45 per m² for spray foam, SAR 40–120 per metre for crack injection, and SAR 10–30 per m² for XPS boards. Which of these fits depends on what the visit finds.

To help the technician, have ready a short note of where the damp shows, whether it is worse after rain or after the air conditioning runs, and whether a bathroom or water tank sits on the other side of the wall. Photos of the stain at different times of day are useful, as are any previous repairs and their dates. Tell the technician if the wall is in a basement, since basement waterproofing is priced separately at SAR 50–150 per m². Clear access to the wall on both sides, and a clear view of any cracks, will let the visit move quickly and give you a firm estimate.

In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.
