Basement & foundation waterproofing in Rafha: for companies (annual contract)

Before we start: what we know about Rafha

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

Rafha sits in the northern desert of Saudi Arabia, with the centre of the town about 451 m above sea level according to SRTM open elevation data. For a company that owns a building with a basement or a below-grade store, that elevation matters less for its height than for the terrain around it. Rafha's flat, open landscape means that rainfall runs off broad surfaces and can pool or seep toward low points, so the first step in any basement or foundation job is to check how water would reach the structure and where it would collect.

Each service we list for this page is priced per square metre or per metre, and the figures give owners a practical sense of scope. Basement waterproofing is quoted at SAR 50–150 per m², a range that reflects how much preparation the substrate needs before a membrane or coating can bond. Crack injection, priced at SAR 40–120 per metre, is often the right route when leaks follow a single line in the wall or slab rather than spreading across the whole area. Epoxy coating at SAR 35–90 per m² and spray foam at SAR 20–45 per m² suit different surfaces and different levels of exposure, so the choice depends on the condition of the concrete and how the space is used. Tank internal coating, at SAR 25–60 per m², applies the same logic to water storage, where the lining must stay sound under constant contact with water.

Owners who manage a company property often avoid a set of predictable errors. They do not wait for a damp patch to spread before calling for an inspection, because a small leak left alone tends to widen. They do not compare quotes only on price per square metre without asking what preparation is included, since a low rate can hide an incomplete surface. They avoid treating the roof and the basement as separate problems when water from one can reach the other through shared walls. They also avoid skipping the drainage outside the building, because a sound membrane cannot do the work of a gutter that directs water away from the foundation. Checking these points early keeps the eventual repair focused and the budget predictable.

For companies, an annual contract sets the scope, the visit schedule and the reports in writing.

Signs that call for 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

Causes we see in the field

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

Tools we use in Rafha

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.
