Basement & foundation waterproofing for restaurants in Hafr Albatin

Before we start: what we know about Hafr Albatin

Team note on Hafr Albatin: 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 Hafr Albatin sits about 312 m above sea level (SRTM open elevation data).

Hafr Albatin sits about 312 m above sea level, which means the land around the city is relatively flat and the water table can rise close to the surface after heavy rain or when irrigation runs nearby. For a restaurant with a basement store, walk-in cooler room or grease trap pit, this matters because groundwater can press against the lower walls for long periods. Waterproofing a basement here is therefore less about shedding surface rain and more about resisting moisture that rises or seeps from the ground, so the work usually starts with the foundation slab and the lower walls rather than the roof.

The practical effect on the service is that we focus first on the basement and the wet zones where water collects. Basement waterproofing is priced from SAR 50–150 per m², and that cost is driven by how much of the wall and floor area is exposed to ground moisture. Epoxy coating, at SAR 35–90 per m², is often used inside kitchen and prep areas where cleaning chemicals and hot water are present, while crack injection, at SAR 40–120 per metre, seals the hairline and structural cracks that let water track through the slab. Bathroom waterproofing, at SAR 15–40 per m², covers staff and customer toilets, which are typically tiled and need a membrane beneath the tiles.

Restaurant owners often make the same few mistakes, and our scope is written to avoid them. A common error is coating a wall without first repairing the cracks behind it, so water simply finds another route. Another is choosing a cheap surface finish for a tank or sump without checking that it suits the contents, which is why tank internal coating, at SAR 25–60 per m², is specified separately. Owners also tend to treat the roof as an afterthought; liquid roof waterproofing at SAR 8–25 per m² and bitumen membrane at SAR 15–35 per m² protect the top of the building, while XPS boards at SAR 12–30 per m² can insulate and protect walls against the ground. Planning the sequence before work begins keeps the kitchen running and the costs predictable.

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

Signs worth paying attention to

• 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.
• Rainwater draining towards the foundation — we check this before anything else.
• Cracks at construction joints — we check this before anything else.

Tools we use in Hafr Albatin

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.
