What is specific about Alquwayiyah for basement & foundation waterproofing

The centre of Alquwayiyah sits about 811 m above sea level (SRTM open elevation data).

Basement and foundation leaks are the most common problem we see in clinics, because the lower floors often hold storage, sterilisation rooms and sometimes plant equipment that cannot afford to get wet. Water usually enters through hairline cracks in the foundation wall or through cold joints where the slab meets the wall. In a clinic, even a small seepage can damage stock, electrical panels and flooring, and it can break the hygiene standards that patient areas must meet. The first job is therefore to find where water is actually getting in, not simply to coat the surface.

Alquwayiyah sits at about 811 m above sea level, which shapes how we approach the work. At this elevation the ground around a building can dry out quickly and then wet up hard after rain, which makes the soil move and presses on basement walls. That is why we tend to look at drainage and the outside face of the foundation as well as the inside. Where cracks are active, crack injection at SAR 40–120 per metre is often the first step, followed by a membrane or coating suited to the wall. For larger wall areas, basement waterproofing at SAR 50–150 per m² is typical, while epoxy coating at SAR 35–90 per m² can suit floors that must stay easy to clean. Spray foam at SAR 20–45 per m² and XPS boards at SAR 12–30 per m² are options where insulation and moisture control both matter.

Before the visit, ask the provider to walk the basement with you and point out any damp patches, cracks and the rooms that hold clinical equipment. Ask whether they will check the outside of the foundation and the drainage around it, not only the inside wall. Request a written scope that lists each area and the method, with the unit rates they will apply, so you can compare it with the ranges above. Ask how they will protect equipment and keep the clinic operating during the works, and when the work can be scheduled around patient hours. A clear scope agreed before work begins protects both the clinic and the contractor.

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

Signs worth paying attention to

Where the problem usually comes from

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