Why basement & foundation waterproofing differs in Aljumum

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..

Is water seeping into my villa's basement in Aljumum, and what will it cost to fix? The answer starts with the place itself. The centre of Aljumum sits about 200 m above sea level (SRTM open elevation data), and that matters for how we plan drainage around a villa's lower levels. Costs depend on the method and the area involved. Basement waterproofing is priced at SAR 50–150 per m², while crack injection runs SAR 40–120 per metre, so a single leaking seam is often a far smaller job than treating the whole floor and walls. Epoxy coating costs SAR 35–90 per m², spray foam SAR 20–45 per m², and bitumen membrane SAR 15–35 per m², so the right choice depends on what is failing and how the water is moving.

Our inspection begins with a walk through the basement and the outside ground around the walls. We look for damp patches, efflorescence on the concrete, and cracks, and we note where the lowest point of the floor sits relative to the surrounding grade. We measure the wall and floor areas so the quote reflects real square metres, and we mark every crack so its length can be priced per metre. Where the basement connects to a bathroom or a water tank, we check those surfaces too, since bathroom waterproofing runs SAR 15–40 per m² and tank internal coating SAR 25–60 per m². We then explain which method suits each surface and why.

Before the visit, please clear the basement walls and floor of stored items so the surfaces can be inspected fully. Tell us about any past leaks, repairs or previous coatings, and note when water appears, whether after rain, after irrigation, or all year round. Have access to the outside wall where possible, and mention any tank or bathroom directly above the basement. With this information ready, the assessment can be completed in one visit and the written quote can show each area and method clearly.

Villas often have several lines and tanks; we test them one at a time so the cause is clear.

Signs worth paying attention to

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

Causes we see in the field

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

How we choose the tool in Aljumum

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.
