Before we start: what we know about Alaridah

The centre of Alaridah sits about 2591 m above sea level (SRTM open elevation data).

Before any quote is given for a basement or foundation job at a rest house or farm in Alaridah, the first thing to check is the height of the site. The centre of Alaridah sits about 2591 m above sea level (SRTM open elevation data), which matters because the ground and weather conditions at that altitude differ from those on the coast, and the technician needs to plan the work around them. Next, the scope is set by the area being treated. Basement waterproofing is priced at SAR 50–150 per m², crack injection at SAR 40–120 per metre, and the cost of each option depends on how much wall or floor is involved, so measuring the exposed surfaces and any cracks is the first practical step.

Some points can only be settled during the site visit. The technician needs to see where water actually enters, whether the cracks are active or old, and whether the soil around the foundation drains away or holds water. The choice between epoxy coating at SAR 35–90 per m², spray foam at SAR 20–45 per m², or bitumen membrane at SAR 15–35 per m² depends on what the surface is made of and how wet it stays, and that judgement is not made from a description alone. The same applies to whether a tank needs internal coating at SAR 25–60 per m², or whether roof work such as liquid waterproofing at SAR 8–25 per m² is also required on the same property. Insulation boards such as XPS at SAR 12–30 per m² are considered only once the ground conditions are known.

To help the technician prepare, it is useful to have the basic layout ready: the approximate length and height of each wall that touches soil, the position of any visible cracks, and a note of any water marks, damp patches or pooling after rain. Tell the technician which rooms are used for storage, sleeping or animal housing, since that affects how quickly the work must be finished. Record the location of the property in relation to its elevation, and mention if the site is exposed to strong wind or heavy seasonal rain. With these details in hand, the site visit can move directly to measurement and a fair per-square-metre or per-metre estimate.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

Signs worth paying attention to

If you notice one of these signs in Alaridah, it is a good moment to talk to the team:

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

Causes we see in the field

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

How we choose the tool in Alaridah

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.
