What is specific about Wadi Aldawasir for basement & foundation waterproofing
The centre of Wadi Aldawasir sits about 683 m above sea level (SRTM open elevation data).
Picture the administrator of a private school in Wadi Aldawasir who notices damp patches creeping up the walls of the basement storage rooms after a rainy spell. The classrooms above are fine, but the lower floor holds archives, sports equipment and a small server room, and each new stain raises the same worry: how far has the water already travelled, and what will it cost to stop it? Owners of school buildings in this position usually want the problem solved without closing wings of the campus during term time, so timing and clear scope matter as much as the repair itself.
The local setting shapes that picture. The centre of Wadi Aldawasir sits about 683 m above sea level, so the town is not a coastal flat where groundwater stands close to the surface, but it is a valley town where rain collects and drains toward lower ground around the buildings. Basement walls in such locations take sustained pressure from surrounding soil after heavy showers, which is why cracks and damp often appear in the same season. For a school, this means the basement is rarely the only area affected; roof edges, plant rooms and bathrooms on the lower levels may show related moisture. Looking at the whole lower envelope, rather than a single wall, gives the owner a more accurate budget.
A practical sequence helps. First, have the site walked after rain so the wet areas, cracks and the direction of water flow can be recorded. Second, separate the work into zones: basement walls and floor, cracks, bathrooms, tanks and roof areas, since each carries its own indicative range, such as basement waterproofing at SAR 50–150 per m² and crack injection at SAR 40–120 per metre. Third, decide the order so that cracks are sealed before the wider membrane or coating goes on. Fourth, schedule noisy and wet work for holiday periods, keeping classrooms and storage routes clear. Finally, record the completed areas and retain the warranty and maintenance notes for the building file.
For schools, the larger jobs are planned for weekends and holidays.
Signs worth paying attention to
The following signs are worth checking before they grow:
- Salt marks at the bottom of the walls
- Damp basement walls
- Water seeping in after rain
Causes we see in the field
- A high groundwater level.
- Rainwater draining towards the foundation.
- Cracks at construction joints.
Tools and methods, and when we use them
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| 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 |
The steps in order
- 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.
