Basement & foundation waterproofing in Arar: the local context

The centre of Arar sits about 553 m above sea level (SRTM open elevation data).

Arar sits about 553 m above sea level, which is a useful starting point for understanding the local ground and weather. Clinics in this area often have basements or lower floors that were built with little thought for moisture, and the site's elevation means rainfall and groundwater behave differently than they would in a low coastal town. Before any work begins, we inspect the foundation walls, slab edges and drainage paths so the waterproofing system matches how water actually moves around the building.

Because of that inland position and the mix of seasonal rain and dry spells, cracks in basement walls and slabs are common, and they are the first thing we seal. Crack injection is priced at SAR 40–120 per metre, so the length of visible cracking determines much of the cost. Basement waterproofing itself runs at SAR 50–150 per m², and the final figure depends on whether the wall is being treated from the inside, the outside, or both. Clinic owners benefit from this planning because it keeps damp away from examination rooms, storage and sterile areas, where moisture can damage equipment and encourage mould.

Several mistakes are easy to avoid with the right approach. Owners sometimes coat a damp surface without drying it first, which traps moisture and causes the new layer to peel. Others choose a single product for every area, when a bathroom may need a flexible coating at SAR 15–40 per m² while a plant room needs a heavier system. Some skip the roof and treat only the basement, even though liquid roof waterproofing at SAR 8–25 per m² can prevent water from reaching the floors below. A clear survey and a staged plan help clinics avoid these errors and keep their spaces dry and functional.

For clinics, work is scheduled around patient hours and kept to the areas that need it.

Signs worth paying attention to

The following signs are worth checking before they grow:

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

Tools and methods, and when we use them

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.
