Why basement & foundation waterproofing differs in Qatif

Team note on Qatif: 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 Qatif sits about 5 m above sea level (SRTM open elevation data).

Qatif is about 2.5 km from the sea coast (OpenStreetMap).

Basement and foundation waterproofing for offices and commercial buildings in Qatif starts with the site's position, because it shapes how water behaves below ground. The centre of Qatif sits about 5 m above sea level, and the town is about 2.5 km from the sea coast. Those two facts mean the technician first checks how groundwater and seawater influence the lower floors, since a low-lying site close to the coast often holds moisture in the soil for longer. Before any quote is firmed up, the team looks at existing walls, floor slabs and the junction where the wall meets the floor, as these are the most common points of entry.

Several things are left to the site visit, because they cannot be judged from a desk. The technician walks the basement to record where dampness appears, how far it spreads, and whether staining follows cracks or the base of the wall. They check the condition of the concrete, note any hollow areas, and assess drainage around the outside of the building. Access, ventilation and the type of use of the space also matter, since an office storage room, a server area and a parking level each place different demands on the finish. The price ranges that apply to the work vary with these findings, from basement waterproofing at SAR 50–150 per m² to crack injection at SAR 40–120 per metre, so measurements taken on site are what allow a realistic figure to be set.

To help the technician prepare, it is useful to share the building plans, the age of the structure, any previous repairs, and photographs of the affected areas taken during wet weather. Information about what the basement is used for, and whether it must stay operational during works, helps plan the sequence of work. Notes on earlier waterproofing, such as bitumen membrane at SAR 15–35 per m² or XPS boards at SAR 12–30 per m², let the technician see what is already in place. Clear dimensions of each wet area and any known leak points allow the visit to focus on what matters most, giving the commercial client a clear and well-informed starting point.

For offices and commercial complexes, work is scheduled to avoid disrupting staff and visitors.

• A high groundwater level — we check this before anything else.

Tools we use in Qatif

From the first visit to the report

1. Finding the source: Groundwater, rain or a pipe — each needs a different treatment.
2. Preparation: Surfaces are cleaned and opened where needed.
3. Injection: Active cracks are injected.
