Basement & foundation waterproofing in Aldawadmi: emergency

Before we start: what we know about Aldawadmi

Team note on Aldawadmi: 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 Aldawadmi sits about 976 m above sea level (SRTM open elevation data).

Main roads in or near Aldawadmi: King Abdulaziz Road, Dawadmi Bujadiyah Road.

Water entering a basement or foundation wall is the most common emergency call for this type of property. In Aldawadmi, the usual pattern is water pushing through hairline cracks in the wall or seeping at the joint where the wall meets the floor slab, often after heavy rain when the ground around the foundation is saturated. Left alone, the damp spreads into stored goods, finishes and any electrical fittings near the floor, so the first priority is to stop the flow and reduce the standing water safely.

The local setting shapes how we approach the repair. The centre of Aldawadmi sits about 976 m above sea level (SRTM open elevation data), so the ground slopes and drains in ways that can push surface water toward the foundation. That means a temporary fix on its own rarely lasts. A permanent solution usually combines crack injection, which is priced at SAR 40–120 per metre, with a suitable waterproofing layer on the wall. Basement waterproofing itself is quoted at SAR 50–150 per m², and an epoxy coating at SAR 35–90 per m², depending on the condition of the surface and how far the damp has travelled. Where the cracks are wide or the wall is heavily affected, the scope is widened so the repair covers the whole affected section rather than only the visible patch.

Before the visit, ask the team to confirm what they will assess and how they will price the job. Ask whether the inspection will look at the source of the water, not just the damp on the wall, and whether the quote will state the area in square metres and the crack length in metres so you can check the figures. Ask which materials they plan to use and their price range, and whether the work includes clearing the affected area. Finally, ask how soon they can attend, what you should move or protect in the meantime, and whether they will give you a written quote before any work begins.

If water is flowing, close the main valve first, then call or message with photos.

Signs worth paying attention to

These are the signs most often linked to basement & foundation waterproofing:

• 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.
• A common cause: rainwater draining towards the foundation.
• A common cause: a high groundwater level.

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.
