Do you need floor and balcony waterproofing for your duplex in Samtah, and how do you know it is needed? Samtah sits about 61 m above sea level, and the centre is about 22.6 km from the sea coast. Those facts matter because they shape the conditions a duplex faces, and a property owner here should weigh them when judging whether floors and balconies are protected. Waterproofing work is priced per square metre or per metre of crack, with bitumen membrane typically SAR 15–35 per m², spray foam SAR 20–45 per m², epoxy coating SAR 35–90 per m², and crack injection SAR 40–120 per m. Your choice of system should follow the surface and the defect, not the lowest figure on a list.

Before any material is recommended, the inspection starts with a walk through every floor and balcony of the duplex. The inspector checks for cracks, ponding water, lifted tiles, and failed old sealant at the junctions with walls and drains. Cracks are measured in metres so that crack injection can be scoped and priced accurately. Balcony slabs and floor areas are measured in square metres, and the inspector notes whether the surface sits at a level where water collects. Where the balcony meets the living area, the inspection records the threshold detail, because that junction is a common route for leaks into the lower unit. The findings are written up so you can see each defect, its measured extent, and the system proposed to treat it.

To make the visit efficient, gather the documents and history you already have. Bring any earlier repair invoices, warranty papers, and drawings showing the balcony and floor build-up. Note where you have seen damp patches, stains, or peeling paint, and when they first appeared. Clear the balconies and floors of furniture and plant pots so the surfaces are fully visible. If the duplex has a rooftop or water tank, make that access available as well. Having these items ready lets the inspector measure in one pass, focus on the real problem areas, and give you a clear, itemised plan for your floors and balconies in Samtah.

In a duplex, the two floors often share lines, so tests are done floor by floor.
