Does a basement flat in Almahd really need waterproofing, given how high and dry the town seems? The centre of Almahd sits about 1047 m above sea level, but altitude does not stop groundwater, seepage through walls, or cracks in a foundation. Basement waterproofing typically costs SAR 50–150 per m², and the right method depends on what the inspection finds, so the figures below are a starting point rather than a quote.
A visit usually begins with a walk through the basement and the adjoining bathrooms to look for damp patches, efflorescence, peeling paint and hairline cracks. Where cracks are found, crack injection is priced at SAR 40–120 per metre, and the length measured on site decides the cost. The inspector then checks the walls and floor for moisture, notes which areas are below ground, and records the exact square metres to be treated. Bathrooms above are assessed separately, at SAR 15–40 per m², because the leak source may be a tile joint rather than the structure. Any water tank in the building is also checked, with internal coating priced at SAR 25–60 per m².
Before the visit, gather what helps the inspector work quickly. Note where the damp appears and whether it worsens after rain or after the water is used upstairs. Take photographs of the stains and cracks, and have the floor plan or measurements of the basement ready so areas can be measured accurately. Clear shelves and stored items away from the walls, and tell the inspector about any previous repairs, since old coatings can affect which products will bond. Finally, list the rooms and tanks you want included, so the quote reflects the full scope and nothing is missed.
In apartment buildings, the floor below is often where a leak shows first.

Tools and methods, and when we use them
| Method | What it helps with | Its role in Almahd |
|---|---|---|
| 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.
