Is basement waterproofing in Riyadh worth the cost, and what should you expect to pay? The centre of Riyadh sits about 637 m above sea level, which places the city on an inland plateau rather than on the coast. For basement and foundation work, the price depends on the method and the area involved. Basement waterproofing is priced at SAR 55–160 per m², while crack injection is charged at SAR 40–125 per metre. Epoxy coating ranges from SAR 35–95 per m², spray foam from SAR 20–45 per m², and bitumen membrane from SAR 15–35 per m². Owners comparing options can use these published ranges to understand where their project is likely to fall.

Before any work is quoted, a site inspection should establish which method suits the structure. The inspector typically walks the basement and foundation walls, notes any cracks and their length in metres, and measures the affected surface in square metres so the quote can be built from the rates above. Where a basement holds water storage, the internal tank surfaces are assessed separately, since tank internal coating is priced at SAR 25–65 per m². The inspector also checks adjoining bathrooms and roofs, because bathroom waterproofing (SAR 15–40 per m²) and liquid roof waterproofing (SAR 10–25 per m²) are distinct jobs that are often booked together. Findings are then recorded so the scope of work is clear before any materials are ordered.

To make the visit productive, gather the basic information about the property first. Have the floor plan or sketch of the basement ready, with rough dimensions so the wall and floor areas can be estimated. Note where you have seen damp, staining, or cracks, and when they first appeared. If the basement is used for storage, clear the walls where possible so the inspector can see the surfaces. Keep any previous repair records or invoices, since they show what has already been tried. Finally, make sure someone with authority over the property is present to approve the scope, so that the method and the price range can be confirmed on the day.

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.
