The most common problem with basements and foundations in residential buildings is water finding its way in through cracks and at the joint where the wall meets the floor slab. Seepage often shows up as damp patches, efflorescence on the concrete, or a musty smell that returns after cleaning. Left alone, moisture can weaken finishes, damage stored belongings, and make a lower floor hard to use. Waterproofing this kind of space usually means treating the structure itself rather than just painting over the surface.
Local conditions matter here. The centre of Afif sits about 1040 m above sea level, which places it in a noticeably higher and cooler setting than the coastal cities many people compare it with. Ground and rainfall behaviour in the area can differ from lowland sites, so a survey should look at how water actually moves around the building rather than assuming a single standard solution. The altitude does not change the materials used, but it is a reason to check drainage paths, slope around the foundation and where runoff collects after heavy rain.
Before booking a visit, ask the provider which method they propose for your basement and why. Common options include epoxy coating, spray foam, crack injection and bitumen membrane, and each is priced differently: basement waterproofing typically falls between SAR 50 and SAR 150 per m², while crack injection is quoted per metre, between SAR 40 and SAR 120 per m. Ask how they will locate the source of the leak, whether they will inspect the outside of the wall as well as the inside, and how they will measure the affected area. A clear written scope, a list of what is included and excluded, and a plan for protecting your belongings during work will help you compare quotes fairly.
For a whole building, a survey of the shared systems comes before unit-by-unit work.

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