Team note on Jubail: 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..

Does a clinic basement in Jubail really need waterproofing when the building is only a short distance from the coast? The answer depends on the ground beneath the structure, and in Jubail that is a real concern. The centre of Jubail sits about 4 m above sea level, and the town lies about 0.9 km from the sea coast. Low, flat land close to the shore means that groundwater and moisture can press against below-grade walls and slabs, so a clinic basement that holds equipment, records or storage rooms needs a clear plan for keeping water out. Basement waterproofing is priced at SAR 50–150 per m², while crack injection is SAR 40–120 per metre, so owners can weigh the scope of work against the size and condition of the space.

The inspection begins with a walk through the basement and the adjoining foundation walls to look for damp patches, efflorescence, staining and active cracks. The technician will mark the cracks and measure their running length, since crack injection is charged per metre. Next, the surfaces are checked to see which system suits them. Epoxy coating, priced at SAR 35–90 per m², is one option for interior faces, while spray foam at SAR 20–45 per m² or XPS boards at SAR 12–30 per m² may suit other sections. Where a water tank sits within the premises, its internal surfaces can be assessed for tank internal coating at SAR 25–60 per m². The inspector records the measured areas so that the quotation reflects the real extent of the work.

Before the visit, the property owner should clear the basement of stored items and equipment so the walls and floor are fully accessible. Gather any previous repair records, drawings or notes about past leaks, because they help the inspector understand where water has entered before. Confirm the clinic's operating hours so that work can be scheduled around patient visits and noisy procedures. It also helps to note which rooms sit directly against the foundation, since those areas will be measured first. With these details ready, the inspection can move quickly and the resulting quotation will match the conditions your clinic actually faces.

For clinics, work is scheduled around patient hours and kept to the areas that need it.

Tools and methods, and when we use them

The steps in order

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.
4. Waterproofing layers: The system is applied on the right side of the wall where possible.
5. Follow-up: Readings are repeated after the treatment.
