Before we start: what we know about Alquwayiyah
The centre of Alquwayiyah sits about 811 m above sea level (SRTM open elevation data).
The owner of a rest house or farm in the hills around Alquwayiyah often has a basement, a sunken store room or a lower floor built into a slope, and it is usually the part of the property that is used least and noticed last. Water finds its way in during the rare but heavy rain, through cracks in the walls, around pipe entries and at the junction between the floor and the wall. By the time damp shows on the inside, the problem has usually been building for some time, so a little attention early is far cheaper than repairing soaked plaster and stored goods later.
The local facts matter here. The centre of Alquwayiyah sits about 811 m above sea level, which places it on higher ground where rainwater runs off the slopes and collects around foundations that were not designed to shed it. Basement waterproofing is priced at SAR 50–150 per m², crack injection at SAR 40–120 per metre, and tank internal coating at SAR 25–60 per m², so an owner should first measure what needs treating and then compare the options. A property on a slope with several cracks may find that injection plus a membrane is more sensible than coating an entire wall, while a farm water tank may need its own separate treatment.
Practical steps help keep the work ordered. Begin by walking the basement or lower floor after rain and marking every damp patch, crack and pipe entry. Next, clear the ground outside the walls where possible so water is not standing against them. Then confirm the area of each surface in square metres and the length of each crack in metres, which lets you price each item against the ranges above. Choose the method that suits each part, such as bitumen membrane or XPS boards for walls and epoxy coating for floors, and let the surfaces dry fully before the next layer goes on. Finish by checking the work after the next rainfall and keeping a simple record of what was treated and when.
Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.
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 — we check this before anything else.
- A common cause: rainwater draining towards the foundation.
- A common cause: 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 |
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.
