Basement & foundation waterproofing in Alula: preventive periodic check
In short: In Alula (Alula), basement & foundation waterproofing (preventive periodic check) begins with the moisture meter for ceilings and walls and the crack injection (polyurethane or epoxy); nothing is opened until the position is clear. The centre of Alula sits about 697 m above sea level (SRTM open elevation data). Pricing starts from Crack injection (per metre) (SAR 40–120 per m), and other items are quoted after the visit.
Why basement & foundation waterproofing differs in Alula
The centre of Alula sits about 697 m above sea level (SRTM open elevation data). Main roads in or near Alula: King Abdullah Road.
Basement and foundation waterproofing in Alula starts with the site's elevation. The centre of Alula sits about 697 m above sea level, which places it on a high desert plateau rather than in a low-lying coastal flood zone. Because of this, the first thing a technician checks is not standing water but the condition of the basement walls and floor slab, looking for old cracks, past repairs, and signs of moisture that has been drawn in from the ground over time. A preventive visit here is about catching small problems early, before they grow into leaks that are costly to fix.
Some matters cannot be settled from a checklist alone and are left to the site visit. The technician needs to see the actual ground conditions around the foundation, how water drains away from the building, and whether any cracks are active or simply old and stable. The depth of the basement, the age and type of the existing waterproofing layer, and whether previous coatings have peeled or blistered can only be judged on the spot. The choice between an epoxy coating, a spray foam layer, a bitumen membrane, or crack injection depends on these findings, and a sensible recommendation is made only after the walls and slab have been examined directly.
To help the technician, it is useful to know the likely cost range for each approach so the client can compare options. Basement waterproofing typically falls between SAR 50 and 150 per m², while epoxy coating ranges from SAR 35 to 90 per m², and spray foam from SAR 20 to 45 per m². Crack injection is priced per metre, at SAR 40 to 120 per m. Where a basement is shared with a bathroom or water tank, the bathroom waterproofing rate of SAR 15 to 40 per m² and the tank internal coating rate of SAR 25 to 60 per m² may also apply. Noting the areas, crack lengths and any wet spots in advance lets the technician give an accurate estimate on the first visit.
Preventive checks follow a written schedule instead of waiting for a fault.

How we choose the tool in Alula
| Tool | What it finds | When we use it in Alula |
|---|---|---|
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
| Crack injection (polyurethane or epoxy) | Stopping active water through cracks | Limits: treats the crack, not the water source |
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.
