What is specific about Khobar for wall damp treatment

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).

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..

Before any treatment starts in Khobar, the first thing we look at is the ground around the building, because the centre of the city sits about 9 m above sea level and the coast is only about 1.8 km away. That combination means water does not always drain away quickly after rain, and sea air carries salt that can work into walls and render. So the technician checks where moisture is actually entering: rising damp from the floor, water tracking down from a roof or terrace, or leaks from a bathroom or external wall. Cracks are noted early, since crack injection is priced per metre and the length found on the wall shapes the job. Surfaces that will be coated, such as basement walls, bathroom floors and tanks, are also measured so the scope matches the area that needs protecting.

The rest is left to the site visit, because it cannot be judged from a description. The technician needs to see the condition of the existing finish, whether the damp is active or old, and how far it reaches up the wall. They will test whether the substrate is dry enough for an epoxy coating or a membrane to bond, and confirm whether a basement, a roof slab or a water tank is involved, since each uses a different system. Access is also assessed on the day: how the roof or basement can be reached, and whether furniture or stored items must be moved. Pricing ranges vary by system, from liquid roof waterproofing at SAR 10–25 per m² to basement waterproofing at SAR 50–150 per m², so the final figure depends on what is found on the wall.

To help the technician, it is useful to have a few details ready before the visit. Note when the damp is worst, for example after rain or during the humid months, and whether it appears on the sea-facing or inland side of the building. Mention any previous repairs, paint or plaster that has been applied, and whether the wall has ever been opened up. Photographs of stains, cracks and bubbling paint are very helpful, as are the approximate sizes of affected areas. If the property has a water tank or basement, say so at the start, so that the right materials, from XPS boards at SAR 10–30 per m² to tank internal coating at SAR 25–60 per m², can be prepared in advance.

Checks before summer and before the rain season catch problems while they are still small.

Tools and methods, and when we use them

From the first visit to the report

1. Moisture readings: Readings are taken in a grid across the wall.
