Basement & foundation waterproofing in Alqunfudhah: the local context

Alqunfudhah is about 0.4 km from the sea coast (OpenStreetMap). The centre of Alqunfudhah sits about 7 m above sea level (SRTM open elevation data).

Team note on Alqunfudhah: 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..

Basement and foundation dampness is the most common problem we see in school buildings, and it tends to show up as seepage through lower walls, efflorescence on the plaster, and cracks where the floor meets the wall. In a school, a damp basement store or plant room is more than a cosmetic issue, because it can affect storage of books, equipment and electrical services, and it creates the conditions for mould in spaces used by children every day.

Alqunfudhah shapes how we approach this work. The centre of the town sits about 7 m above sea level, and it is only about 0.4 km from the sea coast. That closeness to the coast means ground moisture and salt-laden groundwater can be a factor, so we look closely at how water moves through the soil around the foundation before choosing a method. Because the land is low and close to the sea, we do not treat every basement the same. We assess whether the problem is coming through the walls, the floor slab, or a crack, and we match the system to that finding. Options can include a bitumen membrane (SAR 15–35 per m²), epoxy coating (SAR 35–90 per m²), basement waterproofing as a full system (SAR 50–150 per m²), or crack injection (SAR 40–120 per metre), with pricing that depends on the scope agreed after inspection.

Before the visit, it helps to have a few details ready. Tell us which rooms or areas are affected, roughly how large the basement or wet area is in square metres, and whether the damp appears after rain, on a particular wall, or all year. Let us know if any cracks are visible and how long they have been there, and whether the building has had earlier repairs. Ask us to explain the method we propose, what preparation the school will need to arrange, and how the work will be scheduled around teaching time. Having this information lets our visit focus on the cause rather than the symptoms.

For schools, the larger jobs are planned for weekends and holidays.

Signs worth paying attention to

The following signs are worth checking before they grow:

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

Causes we see in the field

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

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.
