Basement & foundation waterproofing in Alhait: the local context
The centre of Alhait sits about 980 m above sea level (SRTM open elevation data).
Picture a homeowner in a residential building who notices a damp patch creeping up a basement wall after a heavy rain. The water seems to come from nowhere, the smell is musty, and the family has started storing things on shelves instead of the floor. They want the problem fixed properly, but they are not sure whether the issue is the wall, the floor slab, or a crack at the joint between them. Like many owners, they are weighing cost against the risk of a repair that fails within a year.
The local facts matter here. The centre of Alhait sits about 980 m above sea level, which places it on higher ground and gives a clear picture of how water behaves on this site. Rain does not simply pool; it moves through soil and finds weak points in the structure. For a basement, that means the foundation walls and the floor-to-wall junction deserve close inspection before any material is chosen. Costs for basement waterproofing run SAR 50–150 per m², while crack injection is priced separately at SAR 40–120 per metre, so an owner can decide whether the work is a targeted repair or a full treatment of the surface.
A practical sequence starts with a dry, careful inspection. First, note where the dampness appears and when it appears, especially after rain. Second, mark every crack and check whether it is active or old. Third, clear the area and let it dry before any product is applied. Fourth, repair cracks by injection where they are found, then decide on the wall treatment, comparing options such as epoxy coating at SAR 35–90 per m², spray foam at SAR 20–45 per m², or a bitumen membrane at SAR 15–35 per m². Finally, ask for the scope to be written down with the areas measured, so the work can be checked against the quote.
For a whole building, a survey of the shared systems comes before unit-by-unit work.

|---|---|---|
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Crack injection (polyurethane or epoxy) | Stopping active water through cracks | Limits: treats the crack, not the water source |
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
From the first visit to the report
- Finding the source: Groundwater, rain or a pipe — each needs a different treatment.
- Preparation: Surfaces are cleaned and opened where needed.
- Injection: Active cracks are injected.
- Waterproofing layers: The system is applied on the right side of the wall where possible.
- Follow-up: Readings are repeated after the treatment.
