What is specific about Khafji for basement & foundation waterproofing

Khafji is about 2 km from the sea coast (OpenStreetMap). The centre of Khafji sits about 9 m above sea level (SRTM open elevation data).

Main roads in or near Khafji: King Abdullah Road. Team note on Khafji: 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..

Basement and foundation waterproofing for restaurants in Khafji usually starts with the same problem: water finding its way through the walls and floor of a space that is used heavily and rarely left dry. Restaurant basements often hold storage, cold rooms, dishwashing areas or service corridors, and a damp slab or leaking wall can quickly affect food storage and hygiene. The first step in our approach is always to trace where the water is coming from, because cracks, joints and the wall-to-floor junction each need a different fix. Typical options include crack injection, priced at SAR 40–120 per metre, and bitumen membrane at SAR 15–35 per m², while basement waterproofing as a whole is priced at SAR 50–150 per m².

Khafji's location shapes how we approach these jobs. The centre of the town sits about 9 m above sea level, and it is roughly 2 km from the coast, so the ground conditions and groundwater behaviour differ from low-lying sites closer to the shoreline. Because the area is not so low that water sits permanently at the surface, we focus on the wall and slab detailing that keeps moisture moving outward rather than pooling against the structure. Where a restaurant has a basement that needs to stay dry for food storage, we often combine membrane work with protective insulation, and XPS boards at SAR 12–30 per m² can be used where thermal and moisture control matter together. Epoxy coating at SAR 35–90 per m² is commonly considered for floors that must be cleaned frequently.

Before the visit, it helps to have a few details ready so the inspection is productive. Tell us which areas of the basement are affected and whether the damp appears after rain, after kitchen use, or all the time. Let us know if the space holds stored food, equipment or a water tank, since a tank internal coating at SAR 25–60 per m² may be part of the scope. Share any past repair records and whether the restaurant has been open during previous work, as this affects how we schedule noisy or messy stages. With these notes, our team can plan the visit around the real cause of the problem.

For restaurants, visits are planned outside service hours and recorded for the premises file.

Signs worth paying attention to

If you notice one of these signs in Khafji, it is a good moment to talk to the team:

• Salt marks at the bottom of the walls
• Damp basement walls
• Water seeping in after rain

Causes we see in the field

• A high groundwater level — we check this before anything else.
• A common cause: rainwater draining towards the foundation.
• A common cause: cracks at construction joints.

How we choose the tool in Khafji

How the work is done, step by step

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.
