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..

Hail sits about 1002 m above sea level, so the first thing a technician checks on a basement or foundation job is how the site sits within that high-plateau setting, not just the water table. Before any price is discussed, the crew looks at the walls, floor joints and any existing cracks, because the rate for basement waterproofing in this area runs from SAR 50–145 per m², and the scope of repair decides where in that range a job falls. Crack injection is priced separately at SAR 40–115 per metre, so every visible crack is logged by its length at the first walk-round. Existing coatings are also inspected early, since epoxy coating at SAR 35–85 per m² and bitumen membrane at SAR 15–35 per m² behave very differently when they are laid over old material.

Some decisions can only be made on the site visit. The technician needs to see how the wall meets the floor, whether there is standing water or staining, and whether the surface is sound enough to take spray foam (SAR 20–45 per m²) or XPS boards (SAR 10–30 per m²). Access, the depth of the excavation and the condition of the drainage around the outside of the building are also judged on the spot. Where a basement adjoins a bathroom or a water tank, those areas are measured separately, because bathroom waterproofing is priced at SAR 15–40 per m² and tank internal coating at SAR 25–55 per m², and each needs its own assessment. Roof areas are checked in the same visit, with liquid roof waterproofing at SAR 10–25 per m².

To help the technician arrive prepared, the office should pass on the building's elevation, the approximate area of each zone in square metres and the total length of visible cracks in metres. It is also useful to note which surfaces are already coated, whether the basement is in use, and any history of leaks or past repairs. With the elevation of Hail known in advance, the crew can plan materials and curing for the local conditions, and with accurate measurements the quotation can match the real scope of work rather than a rough estimate.

For companies, an annual contract sets the scope, the visit schedule and the reports in writing.

Signs worth paying attention to

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

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

Causes we see in the field

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

How we choose the tool in Hail

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.
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.
