Basement & foundation waterproofing for villas in Rastanura

Before we start: what we know about Rastanura

Rastanura is about 0.2 km from the sea coast (OpenStreetMap). Team note on Rastanura: 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..

Rastanura sits about 0.2 km from the sea coast (OpenStreetMap), so villa basements and foundations here live close to salt-laden air and a high water table. That proximity means moisture and salt can work their way into concrete and block walls over time, and owners often notice damp patches or efflorescence before any real structural trouble appears. Our assessment for this area starts with checking how the ground and walls are holding moisture, not just treating the surface you can see.

Each part of the site is priced separately so you can match the treatment to the risk. Basement waterproofing runs from SAR 50–150 per m², bitumen membrane from SAR 15–35 per m², and XPS boards from SAR 12–30 per m². Because the coastline nearby keeps the ground damp, we typically recommend a membrane or board system on the external face where possible, rather than relying on a coating alone. Cracks found during inspection are sealed by crack injection at SAR 40–120 per metre, and epoxy coating at SAR 35–90 per m² can be added inside once the structure is dry and sound.

Owners in this area commonly make a few avoidable mistakes. They often paint over damp walls without first stopping the source, which traps moisture and makes the problem worse. Others leave hairline cracks unsealed because they look minor, then find water tracking in after the next rain. Some skip the roof and tank, forgetting that liquid roof waterproofing at SAR 8–25 per m² and tank internal coating at SAR 25–60 per m² protect the same building from below and above. Checking the whole envelope early, rather than one wall at a time, is the simplest way to avoid repeat work.

In a villa, tanks, the roof and the yard lines are usually yours to look after, so it helps to know where the main valve and tank hatches are.

When do you need basement & foundation waterproofing?

The following signs are worth checking before they grow:

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

Where the problem usually comes from

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

Tools and methods, and when we use them

How the work is done, step by step

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.
