Basement & foundation waterproofing in Hail: the local context

The centre of Hail sits about 1002 m above sea level (SRTM open elevation data). Team note on Hail: 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 hotels and serviced apartments in Hail starts with the site's altitude. The centre of Hail sits about 1002 m above sea level (SRTM open elevation data), so our technicians first look at how water moves across the plot and where it is likely to collect against lower walls and slabs. Because a basement is the lowest part of any building, it is the first place a technician checks for ground-water pressure, old cracks and any signs of previous seepage. The basement waterproofing rate is SAR 50–145 per m², and that range reflects how much surface must be treated and how the existing structure responds to the work.

Several things can only be judged on the day of the site visit. The technician confirms the condition of the concrete, the depth of the excavation, the drainage around the perimeter and whether the building has an existing membrane or coating that must be removed or kept. Crack injection, priced at SAR 40–115 per metre, is decided after the cracks are mapped and their movement is assessed. The choice between epoxy coating (SAR 35–85 per m²), spray foam (SAR 20–45 per m²), bitumen membrane (SAR 15–35 per m²) or XPS boards (SAR 10–30 per m²) depends on access, the building's use and how much disruption guests can accept. Tank internal coating (SAR 25–55 per m²) is considered wherever a water store sits within the same structure.

To help the technician prepare, please share the floor plans, the age of the building, any earlier repair records and the dates when damp or staining was first noticed. Note which areas are in active use by guests or staff, and whether bathrooms on lower floors need separate treatment, which is priced at SAR 15–40 per m². Mention any roof or liquid roof waterproofing (SAR 10–25 per m²) already planned, so the two jobs can be coordinated. Clear access to the basement, the car park and the plant room will shorten the visit and allow a more accurate scope and quotation.

For hotels and serviced apartments, rooms are handled in batches to keep units available.

Signs worth paying attention to

These are the signs most often linked to basement & foundation waterproofing:

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

The most common causes

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

Tools we use in Hail

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.
