Why basement & foundation waterproofing differs in Alhait

The centre of Alhait sits about 980 m above sea level (SRTM open elevation data).

At Alhait, which sits about 980 m above sea level according to SRTM open elevation data, the first thing a technician checks on a clinic basement or foundation job is how water reaches the structure in the first place. Because the site is at this elevation, the team looks at the existing drainage, the ground level around the building and any signs of seepage at the base of walls before deciding on a system. Basement waterproofing for a clinic is priced at SAR 50–150 per m², and that range reflects how much access and preparation the existing wall needs, so the first inspection focuses on wall condition, joints and any active leaks.

Several points can only be settled at the site visit. The technician must confirm the actual wall area and the length of any cracks, since crack injection is charged at SAR 40–120 per metre and the total depends entirely on what is found. The choice between epoxy coating at SAR 35–90 per m², spray foam at SAR 20–45 per m² and XPS boards at SAR 12–30 per m² depends on whether the wall is dry, damp or actively leaking, and on how much clinic traffic and equipment access the space can tolerate. Adjacent wet areas such as washrooms may need bathroom waterproofing at SAR 15–40 per m², and any water storage tank in the building may need internal coating at SAR 25–60 per m². Roof sections, where liquid roof waterproofing runs SAR 8–25 per m² and bitumen membrane SAR 15–35 per m², should be inspected in the same visit so the whole building is covered in one plan.

For the technician, the useful information is the sequence of work and the clinic's constraints. Record the water source, the wall material, any crack widths and locations, and the hours when the clinic can be disrupted, since noisy or odour-producing materials may need to be scheduled around patient care. Photograph each wall section with its measured area and label it so the quotation can match each element to a per-unit rate. Note any existing coatings, as these affect adhesion and the preparation needed before the new system goes on.

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

Signs worth paying attention to

If you notice one of these signs in Alhait, 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 high groundwater level.
• A common cause: rainwater draining towards the foundation.

How we choose the tool in Alhait

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.
