Basement & foundation waterproofing for hotels & serviced apartments in Alula

Before we start: what we know about Alula

Main roads in or near Alula: King Abdullah Road. The centre of Alula sits about 697 m above sea level (SRTM open elevation data).

Basement and foundation waterproofing for hotels and serviced apartments in Alula starts with the site's elevation, which matters more than many residents expect. The centre of Alula sits about 697 m above sea level (SRTM open elevation data), so ground water behaves differently than it would on a coastal plain, and the first thing we check is how water actually reaches the lower floors. Our technicians look at the lowest slab, the wall-to-floor joints, and any existing cracks before quoting, because these are the points where moisture enters and where a surface treatment alone will fail. Pricing for basement work is usually set per square metre, with a typical range of SAR 50–150 per m² depending on the condition of the substrate, so the extent of the defects we find in the first inspection shapes the scope.

Several things are left to the site visit, because they cannot be judged from drawings or a phone call. These include the depth and direction of any water pressure against the walls, the state of drainage around the building, whether previous coatings have been applied and are lifting, and how the surfaces have been prepared. Crack repair is measured per metre and falls within SAR 40–120 per m, but the number of cracks, their width, and whether they are active only become clear on site. Where the work touches bathrooms, wet areas, roofs or water tanks, the choice of system also depends on what the surface is made of and how it is used day to day. We will recommend an approach only after seeing these conditions in person.

To help the technician arrive prepared, please share the building's age, the number of basement levels, any history of leaks or damp patches, and whether the hotel or apartment block operates while work is underway. Access times for guest areas, plant rooms and car parks should be agreed in advance, and any existing plans or previous repair records are useful. Indicative per-square-metre ranges across our services include epoxy coating at SAR 35–90, spray foam at SAR 20–45, bitumen membrane at SAR 15–35, and XPS boards at SAR 12–30, though the final system is chosen on site rather than from a list.

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

Signs worth paying attention to

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

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

The most common causes

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

Tools and methods, and when we use them

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.
