What is specific about Afif for basement & foundation waterproofing

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

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..

The centre of Afif sits about 1040 m above sea level, according to SRTM open elevation data. For warehouse owners, that elevation matters because it shapes how the land drains and how water moves through the ground around a building. Sites at this height often see water collect and shift in different ways than low-lying plots, so a waterproofing plan should start with how the site actually sits rather than a generic template. A survey of the slab and the surrounding ground helps decide where protection is most needed.

Because of that elevation, the service focuses first on the basement and foundation walls, where groundwater pressure and seepage tend to be the main concern. Basement waterproofing is priced at SAR 50–150 per m², and the final figure depends on the condition of the surface and how much preparation it needs. Crack injection, priced at SAR 40–120 per metre, is often used where leaks show up along joints or fine cracks, sealing the path before a full coating goes on. Epoxy coating at SAR 35–90 per m² can then be applied to floors and walls that carry heavy use, while tank internal coating at SAR 25–60 per m² suits any water storage on site. Each option links to the job it does, so the right combination depends on what the warehouse stores and how it is used.

Owners of warehouses in Afif often avoid the same few mistakes. Many skip a proper inspection and apply coating over a damp or dusty surface, which stops the layer from bonding and leads to early failure. Others treat the roof and the foundation as separate problems, when water that enters at the roof can travel down and reach the basement. Liquid roof waterproofing at SAR 8–25 per m² and bitumen membrane at SAR 15–35 per m² each work only when the surface is prepared and the details at edges and drains are handled correctly. Choosing the lowest quote without checking what is included is another frequent error, since missing preparation or edge sealing costs more to fix later.

For warehouses, work is phased around operations and stored goods.

Signs that call for basement & foundation waterproofing

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

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

Where the problem usually comes from

• A high groundwater level.
• A common cause: rainwater draining towards the foundation.
• Cracks at construction joints — we check this before anything else.

How we choose the tool 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.
