Does a basement in Alqunfudhah really need waterproofing when the town is so close to the coast? The answer depends on the site itself. The centre of Alqunfudhah sits about 7 m above sea level, and the town is about 0.4 km from the sea coast. That combination means ground water and moisture pressure around a below-grade space deserve a proper check rather than an assumption. Basement waterproofing here is priced per square metre, typically between SAR 50 and SAR 150 per m², with crack injection priced separately at SAR 40–120 per metre.

Our inspection starts with a walk through the basement and foundation walls to look for damp patches, efflorescence, staining, and any visible cracks. The team measures the wall and floor areas that would need treatment and marks each crack so its length can be recorded. Where a crack is active, it is noted separately, since it is often treated by injection before a membrane or coating is applied. The inspector also checks the adjoining bathroom and any tank in the same structure, because these are quoted on their own rates: bathroom waterproofing at SAR 15–40 per m², and tank internal coating at SAR 25–60 per m². Based on what is found, the inspection leads to a written scope that compares options such as bitumen membrane at SAR 15–35 per m², epoxy coating at SAR 35–90 per m², or spray foam at SAR 20–45 per m².

Before the visit, it helps to clear the basement or at least move stored items away from the walls so the surfaces can be seen. Note any past leaks, when they happened, and whether they followed heavy rain or irrigation. Have the dimensions of the basement floor and walls ready, along with the length of any known cracks. If the building has a roof terrace, mention any ponding or leaks there too, since liquid roof waterproofing is quoted at SAR 8–25 per m² and XPS insulation boards at SAR 12–30 per m² may be relevant. Clear access to the sump or drainage points, if present, will let the inspector assess how water is moving through the site.

The aim is to locate the cause with instruments first, so any opening is limited to one point.

Signs that call for basement & foundation waterproofing

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

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

The most common causes

• 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

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.
