Why basement & foundation waterproofing differs in 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).

Does a rest house or farm in Alula need waterproofing below ground level, and how do you know if it does? Alula sits about 697 m above sea level, and its dry climate means long stretches without rain. Still, when storms do arrive, water finds its way into basements and foundations, especially where the ground around a building slopes towards the walls. Basement waterproofing is priced at SAR 50–150 per m², which makes the first step of understanding your structure worth taking before choosing a method.

Our inspection begins with a walk around the outside of the building to check grading, drainage and any signs of moisture rising along the foundation. Inside, the technician looks at the basement or lower floor walls for damp patches, staining and efflorescence, and measures the areas that will need treatment. Cracks are traced and mapped, since crack injection is charged at SAR 40–120 per metre and needs an accurate length. Where water is stored, such as a farm tank, the internal surfaces are checked for coating condition. Roofs are examined for ponding and worn surfaces. Each area is then matched to a suitable system, whether epoxy coating at SAR 35–90 per m², spray foam at SAR 20–45 per m², bitumen membrane at SAR 15–35 per m², or XPS boards at SAR 12–30 per m².

Before the visit, clear access to the basement, the outdoor walls and the roof so the technician can work without delay. Note any leaks you have seen, when they happen and after which kind of weather, as this history helps narrow the cause. Move stored items away from the walls where you can, and provide the approximate size of the affected areas. If the building has a tank or bathrooms that also show damp, mention them too, since bathroom waterproofing at SAR 15–40 per m² and tank coating at SAR 25–60 per m² are often considered together. Having these details ready lets the inspection focus on what matters and gives you a clear picture before any work is agreed.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

Signs that call for basement & foundation waterproofing

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

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

Where the problem usually comes from

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

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.
