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).

Floor and balcony waterproofing in Dhahran most often fails at the joints and edges rather than across the open surface. Water finds its way in where a balcony slab meets the wall, where floor tiles abut a drain, and where hairline cracks open up over time. For that reason, a sound job starts with a close inspection of these junctions before any product is chosen. A reliable provider will look at where water is actually getting through, not simply quote a flat rate for the whole area.

Dhahran's location shapes the approach. The centre of Dhahran sits about 16 m above sea level, and the city is about 5.9 km from the sea coast. Those facts mean that water does not pool or rise the way it might on low, flood-prone ground near the shoreline, so the focus is usually on surface run-off, drainage outlets and the condition of the membrane itself. Balconies and floors here are generally assessed for how water moves across them and away, which is why the scope of work often centres on sealing edges and renewing the top layer rather than tackling deep rising damp.

Before booking a visit, ask the provider which system they propose for your specific surface and why. Request that they measure the area in square metres and the length of any cracks in metres, since published rates are quoted per m² or per metre, and you can then check the estimate against those units. For floors and balconies, typical published ranges include spray foam at SAR 20–45 per m², epoxy coating at SAR 35–90 per m², crack injection at SAR 40–120 per m, and liquid roof waterproofing at SAR 8–25 per m². Ask what is included, how the surface will be prepared, and how long the warranty period is stated in writing.
