Basement & foundation waterproofing in Dhahran: the local context

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

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..

The first thing checked for a rest house or farm in Dhahran is how close the structure sits to the water table and the coast. The centre of Dhahran sits about 16 m above sea level (SRTM open elevation data), and Dhahran is about 5.9 km from the sea coast (OpenStreetMap). Those two facts shape the first questions a technician asks: whether ground water is likely to press against the lower walls, and whether salty air may be affecting exposed concrete and fixings. Because most rest houses and farm buildings have ground-level or semi-sunken storage, we start by confirming where the lowest slab and walls meet the soil, and whether any water has already left stains or efflorescence.

Several things are left to the site visit, because they cannot be judged from a description. The technician will walk the perimeter to see how rainwater drains away from the building, check for cracks, damp patches and blistered paint, and identify any joints or penetrations that might leak. They will also measure the areas involved, since pricing for basement waterproofing is set per m² in a range of SAR 50–150 per m², crack injection is priced per metre at SAR 40–120 per m, and liquid roof waterproofing runs SAR 8–25 per m². Which system suits each surface, whether epoxy coating at SAR 35–90 per m², spray foam at SAR 20–45 per m², a bitumen membrane at SAR 15–35 per m², or XPS boards at SAR 12–30 per m², depends on what the site reveals, so that decision is made only after inspection.

To help the technician prepare, it is useful to have a few details ready: the approximate age of the building, any past repairs, the use of each space such as storage, livestock areas or water tanks, and any tank internal coating needs, which are priced at SAR 25–60 per m². Photographs of problem areas taken after rain are especially helpful, as are notes on when dampness appears. Bathroom waterproofing, priced at SAR 15–40 per m², may be included where wet rooms are part of the rest house. Clear information at the start lets the visit focus on the real causes of water entry rather than guesswork.

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

Signs that call for basement & foundation waterproofing

These are the signs most often linked to basement & foundation waterproofing:

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

The most common causes

• 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.

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.
