Why basement & foundation waterproofing differs in Alqunfudhah

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.. The centre of Alqunfudhah sits about 7 m above sea level (SRTM open elevation data).

Alqunfudhah is about 0.4 km from the sea coast (OpenStreetMap).

Basement and foundation waterproofing in Alqunfudhah begins with the site's position. The centre of Alqunfudhah sits about 7 m above sea level, and the town lies about 0.4 km from the sea coast. Because of this closeness to the coast and low elevation, technicians first check whether groundwater or salt-laden moisture could be reaching the lower walls and floor slab. The first questions are therefore where water enters the structure, whether any previous coating has failed, and how far damp has travelled up the wall from the footing.

Several things are left to the site visit, because they cannot be judged from a distance. These include the depth of the basement below ground, the condition of the concrete, the width and movement of any cracks, the drainage slope around the building, and whether water is coming through the wall, the joint between wall and floor, or the slab itself. Technicians will also confirm the surface area to be treated, since pricing for basement work is set per square metre. Typical reference ranges for the main options are SAR 50–150 per m² for basement waterproofing, SAR 35–90 per m² for epoxy coating, SAR 15–35 per m² for bitumen membrane, and SAR 12–30 per m² for XPS boards, with crack injection at SAR 40–120 per metre. The final choice depends on what the inspection reveals, not on price alone.

To help the technician, residents and property managers should note any past leaks, the age of the building, previous repairs, and where damp appears after rain or on humid days. Photographs of stains, cracks and wet patches, along with the approximate length and height of the affected walls, speed up the visit. Access to the basement and any drainage points should be arranged in advance, and the level of standing water or dampness should be described honestly. This information lets the technician plan the right method and quantity of materials before arriving on site.

For a whole building, a survey of the shared systems comes before unit-by-unit work.

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

Causes we see in the field

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

Tools and methods, and when we use them

From the first visit to the report

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.
