Basement & foundation waterproofing in Alaridah: before summer & rain season
الخلاصة: In short: In Alaridah (Alaridah), basement & foundation waterproofing (before summer & rain season) 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 Alaridah sits about 2591 m above sea level (SRTM open elevation data).
Before we start: what we know about Alaridah
The centre of Alaridah sits about 2591 m above sea level (SRTM open elevation data).
The centre of Alaridah sits about 2591 m above sea level, according to SRTM open elevation data. At that height the ground and the air around it can change quickly, and a home that looks dry in the morning can still hold moisture in its lower walls by evening. For basement and foundation work, this means we inspect the ground level and drainage path before quoting, so the membrane is planned around how water actually moves toward the structure rather than a generic layout.
Because of the elevation, the season matters as much as the site. Our work is best scheduled before summer, when the surfaces have time to cure fully before the hotter months arrive. Pricing for basement waterproofing runs at SAR 50–150 per m², and the final figure depends on the wall condition, access and the system chosen. Epoxy coating is priced at SAR 35–90 per m², spray foam at SAR 20–45 per m², and crack injection at SAR 40–120 per metre, so a surveyor can match the method to the defect instead of applying one product across the whole space.
Owners in Alaridah often avoid the same few mistakes, and a short checklist of them helps. The first is leaving a wet wall to dry too fast under sun, which can crack the new layer. The second is patching a visible leak while ignoring the cracks around it, since water will simply find the next gap. The third is coating a surface that still carries dust, oil or old paint, which weakens adhesion from the start. The fourth is treating the roof and the basement as separate problems when shared drainage can connect them. Planning these checks early keeps the work durable through the dry season and the rains that follow.
Checks before summer and before the rain season catch problems while they are still small.

Tools and methods, and when we use them
| Tool | What it finds | When we use it in Alaridah |
|---|---|---|
| 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.
