Basement & foundation waterproofing in Rafha: the local context

The centre of Rafha sits about 451 m above sea level (SRTM open elevation data).

Is basement waterproofing in Rafha worth paying for, and what should it cost? Rafha sits about 451 m above sea level, in the northern desert of Saudi Arabia, and the published rates for below-ground work are a useful starting point. Basement waterproofing is listed at SAR 50–150 per m², and crack injection, which is often the first step when water finds a route in, is listed at SAR 40–120 per metre. Epoxy coating, used on floors and walls where a hard, sealed finish is wanted, runs SAR 35–90 per m². Spray foam, another option for walls, is SAR 20–45 per m². Because these are per-unit rates, the final figure depends on the area and length actually treated, so the wider measurements matter more than any single number.

The visit usually starts with the property being walked and measured. The inspector looks at the basement walls and floor for damp patches, efflorescence, cracks and any signs that water is entering at a joint or corner. Each crack is measured in metres so injection can be priced, and the surfaces to be coated are measured in square metres. If there is a water tank, its internal condition is checked too, since tank internal coating is priced separately at SAR 25–60 per m². The aim of the inspection is to separate the areas that need full coating from those that only need localised repair, so the quote reflects what is really needed rather than a blanket treatment.

Before the visit, it helps to gather a few things. Note where you have seen water, damp or staining, and when it appears, for example after rain or on humid days. Know the approximate length and height of the basement walls and the floor area, so the measurements can be checked against your own records. If you have an existing waterproofing or bitumen membrane record, bring it along. Clear access to the basement and any tanks will save time. With these details ready, you can compare each line of the quote against the published ranges above and ask the reason for any figure that falls outside them.

Prices shown on this page come from our own published price list for the city; the final price is set after inspection.

When do you need basement & foundation waterproofing?

The following signs are worth checking before they grow:

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

Where the problem usually comes from

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

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.
