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

Before we start: what we know about Rastanura

Rastanura is about 0.2 km from the sea coast (OpenStreetMap). Team note on Rastanura: 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..

Does a commercial basement in Rastanura really need waterproofing when it is only a short distance from the shore? Rastanura sits about 0.2 km from the sea coast, which means the ground around a company's foundation can be exposed to salt-laden moisture and groundwater that works its way against concrete walls over time. For a business that stores stock, server equipment or records below ground, even a small seep can cause real damage. Basement waterproofing is priced at SAR 50–150 per m², and for companies the right method depends on what the basement is used for and how the water is getting in.

Our inspection starts with the walls and floor slab, which are checked for cracks, damp patches, efflorescence and signs of standing water. Where cracks are found, crack injection is quoted at SAR 40–120 per metre, so each defect can be measured and costed separately. The surfaces are then assessed to decide between an epoxy coating at SAR 35–90 per m², a spray foam system at SAR 20–45 per m², or a bitumen membrane at SAR 15–35 per m². Where a basement is partly used for water storage, tank internal coating at SAR 25–60 per m² is also considered. The inspector records measured areas so the quotation reflects the actual surfaces rather than estimates.

Before the visit, please gather the building's drawings or any previous repair records, and note where water has appeared and after which kinds of weather or usage. Clear the basement of stored goods along the walls so the surfaces can be seen, and make sure someone who knows the building's layout is available to answer questions. If the roof or adjoining bathrooms are also affected, mention this, because liquid roof waterproofing at SAR 8–25 per m² and bathroom waterproofing at SAR 15–40 per m² can be assessed during the same visit. Having this information ready helps the inspection move quickly and keeps the final quotation clear.

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

Signs worth paying attention to

The following signs are worth checking before they grow:

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

The most common causes

• A common cause: cracks at construction joints.
• A common cause: rainwater draining towards the foundation.
• A common cause: a high groundwater level.

Tools and methods, and when we use them

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.
