Before we start: what we know about Dhahran

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.. 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).

Will a clinic basement in Dhahran really need waterproofing, given that the city is not right on the coast? The centre of Dhahran sits about 16 m above sea level, and the city is about 5.9 km from the sea coast. Those distances mean that wet ground and seepage are not a problem tied only to the shoreline, and a clinic below ground level should not assume it is safe from moisture. Basement waterproofing for a clinic is priced at SAR 50–150 per m², and crack injection, where a wall has a visible fault, is priced at SAR 40–120 per metre. Epoxy coating, spray foam and XPS boards are other options whose cost depends on the surface and the method chosen.

When we visit a site, the inspection starts with the basement walls, floor and any joints where walls meet the floor. We look for damp patches, staining, efflorescence and cracks, and we measure the wet areas so the quote reflects the actual square metres involved. Where cracks are found, we record their length in metres so that crack injection can be costed separately from the surface work. We also check adjoining areas that affect the basement, such as the clinic's bathrooms, where bathroom waterproofing is priced at SAR 15–40 per m², and any water tanks, where tank internal coating is priced at SAR 25–60 per m². The aim of the inspection is to show the owner exactly which surfaces need treatment and which can be left alone.

To make the visit efficient, please prepare access to every basement room, including any plant or storage spaces, and clear the walls so the surfaces can be examined directly. Gather any previous plans, drawings or records of past leaks or repairs, since these help identify where water has entered before. Note when damp is most noticeable, for example after rain or during particular seasons, and tell us about any clinic equipment or stored items that need to be moved. If the building has a water tank or bathrooms near the basement, make sure those areas can be opened for inspection. With this information ready, the inspection can focus on the places that matter for your clinic.

For clinics, work is scheduled around patient hours and kept to the areas that need it.

Signs worth paying attention to

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

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

The most common causes

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

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.
