Basement & foundation waterproofing in Afif: the local context

The centre of Afif sits about 1040 m above sea level (SRTM open elevation data). Main roads in or near Afif: King Abdulaziz Road, King Faisal Road, Airport Road.

Team note on Afif: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins..

Does a rest house or farm in Afif really need basement and foundation waterproofing, given how dry the air can feel on the hills? The answer depends on the ground beneath the building, not the sky above it. The centre of Afif sits about 1040 m above sea level (SRTM open elevation data), and at that height, sloping plots, runoff after rare heavy rain, and seepage through old concrete can still find their way into a basement or the lower walls of a farm building. Waterproofing work for this kind of property typically ranges from SAR 50–150 per m² for a basement, SAR 40–120 per metre for crack injection, and SAR 12–30 per m² for XPS boards placed against the outer face of the foundation.

Our inspection starts with a walk around the outside of the structure to look at ground levels, drainage paths and any visible cracks or staining. Inside, we check the basement floor and lower walls for damp patches, efflorescence and hairline cracks, and we note where water seems to enter. We then mark the areas that need treatment, measure them, and separate the options by method and by cost. Where a crack is the cause, crack injection is priced per metre; where the surface is damp across a wide area, a coating or membrane is usually considered. We explain the reasons for each recommendation before any work is agreed, so the owner can see why one option is suggested over another.

Before the visit, it helps to clear access to the basement and the outer foundation walls, and to note when you last saw water entering, including after which kind of rain. Photos of any damp areas taken over several weeks are useful, as are any earlier repair records or plans of the building. If the property has a water tank or a rooftop, mention those too, because tank internal coating (SAR 25–60 per m²) and liquid roof waterproofing (SAR 8–25 per m²) are sometimes part of the same job. Clear information at the start means a more accurate assessment and fewer surprises once the work begins.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

Signs worth paying attention to

If you notice one of these signs in Afif, it is a good moment to talk to the team:

• Damp basement walls
• Salt marks at the bottom of the walls
• Water seeping in after rain

Where the problem usually comes from

• A common cause: rainwater draining towards the foundation.
• A common cause: a high groundwater level.
• Cracks at construction joints.

Tools we use in Afif

The steps in order

1. Finding the source: Groundwater, rain or a pipe — each needs a different treatment.
2. Preparation: Surfaces are cleaned and opened where needed.
3. Injection: Active cracks are injected.
4. Waterproofing layers: The system is applied on the right side of the wall where possible.
5. Follow-up: Readings are repeated after the treatment.
