Basement & foundation waterproofing in Dhahran: the local context

Dhahran is about 5.9 km from the sea coast (OpenStreetMap). The centre of Dhahran sits about 16 m above sea level (SRTM open elevation data).

Team note on Dhahran: 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..

Before any work starts on a basement or foundation in Dhahran, the first thing to check is how close the structure sits to water, because the city's location shapes the risk. The centre of Dhahran sits about 16 m above sea level, and the city is about 5.9 km from the sea coast. Those two facts mean that groundwater behaviour and salt exposure are worth examining early, rather than assuming that a dry-looking wall is a dry wall. A technician should walk the lower floors, look at any staining, efflorescence or damp patches, and note where the walls meet the slab, since these joints are where moisture most often enters.

Some matters cannot be settled from a checklist and are left to the site visit. The exact depth of the foundation relative to the water table, the condition of existing drainage, the presence of older coatings that could trap moisture behind a new layer, and the actual extent of any cracks all need to be measured in person. Costs also depend on these findings. For reference, basement waterproofing is usually priced at SAR 50–150 per m², crack injection at SAR 40–120 per metre, and epoxy coating at SAR 35–90 per m², but the right choice between these systems can only be made once the site has been inspected and the surfaces tested.

For the technician, a few details will make the job run smoothly. Record the total wall and floor area in square metres, the length of any cracks in metres, and whether the basement also contains a water tank, since tank internal coating is priced separately at SAR 25–60 per m². Note whether the bathrooms above need attention too, as bathroom waterproofing runs at SAR 15–40 per m², so that work can be scoped alongside the basement. Photograph each problem area before and after preparation, and agree with the client on access, ventilation and timing before materials are opened. Clear communication at this stage prevents most disputes later and keeps the preventive work focused on the places where water is most likely to find its way in.

Preventive checks follow a written schedule instead of waiting for a fault.

How we choose the tool in Dhahran

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.
