What is specific about Aljumum for basement & foundation waterproofing

The centre of Aljumum sits about 200 m above sea level (SRTM open elevation data). Team note on Aljumum: 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..

Aljumum sits about 200 m above sea level, and its centre is a settled, built-up district of clinics, offices and residential blocks. For a clinic owner, this elevation matters less for flooding than for how water moves through the ground. Sites on higher ground tend to see groundwater pressure build from the surrounding slope rather than from pooling water, so the basement walls and floor slab of a clinic can face steady moisture rather than sudden inflow. Our basement and foundation waterproofing work is planned around that pattern, with attention to where water is most likely to enter and how it will travel toward the walls.

Each part of the building responds to that moisture differently, so the work is priced and specified by area. Basement waterproofing runs at SAR 50–150 per m², bathroom waterproofing at SAR 15–40 per m², and epoxy coating at SAR 35–90 per m². Spray foam costs SAR 20–45 per m², while crack injection is charged per metre at SAR 40–120 per m. Liquid roof waterproofing runs at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², and XPS boards at SAR 12–30 per m². Tank internal coating, where a clinic holds water on site, costs SAR 25–60 per m². Because clinics combine wet treatment rooms, plant rooms and below-ground storage, we usually split the quote by surface so you can see what each zone needs.

Clinic owners often avoid the same expensive errors when they plan this work. They rarely wait until a damp patch appears on a clinical wall before calling for an inspection, and they do not treat a hairline crack as cosmetic, since cracks are the usual route for moisture into a basement. They also avoid choosing a coating only on price, without checking whether it suits the moisture level and the use of the room. Finally, they do not leave bathroom and roof junctions out of the plan, because a basement fix that ignores the rest of the building tends to move the leak rather than stop it.

For clinics, work is scheduled around patient hours and kept to the areas that need it.

When do you need basement & foundation waterproofing?

The following signs are worth checking before they grow:

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

Where the problem usually comes from

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

Tools and methods, and when we use them

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.
