Do you really need floor and balcony waterproofing in Dhahran, and what should you check before you buy? The city's position answers the first part. The centre of Dhahran sits about 16 m above sea level, and the sea coast is about 5.9 km away, so the local ground is not at the waterfront. That matters when you judge how water moves across a balcony or floor slab. The cost of work also varies widely, so it helps to know the range before you ask for a quote. Basement waterproofing typically falls between SAR 50–150 per m², bathroom waterproofing between SAR 15–40 per m², and epoxy coating between SAR 35–90 per m². Spray foam runs SAR 20–45 per m², while bitumen membrane sits at SAR 15–35 per m².

The inspection should start with the surfaces you can see and walk. Look at the floor and the balcony edges for hairline cracks, and mark any that run through the surface. A crack can be sealed by crack injection, which costs SAR 40–120 per metre, so measure its length rather than guessing. Check the junction where the balcony meets the wall and the drainage points, since water often collects there first. If the building has a roof terrace, note whether the surface is covered by liquid roof waterproofing, which costs SAR 8–25 per m², or by a membrane. If there is a water storage tank nearby, ask about its inside; tank internal coating is priced at SAR 25–60 per m². Compare the existing finish with what the inspector records, and ask them to explain each finding in plain terms.

Before the visit, prepare a simple record of the area. Measure the floor and balcony in square metres, note any basement or bathroom areas separately because each has its own rate, and count the length of visible cracks in metres. Gather any earlier repair notes, photographs of stains or damp patches, and the dates you first noticed them. Note which rooms are above insulation boards, since XPS boards cost SAR 12–30 per m² where they are used. Having these figures ready lets the inspector focus on the real problem and lets you compare written quotes on equal terms.

Before buying or taking over a property, an inspection gives you findings in writing before you sign.
