Why floor & balcony waterproofing differs in Tabuk

The centre of Tabuk sits about 762 m above sea level (SRTM open elevation data). Team note on Tabuk: 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..

Does a duplex in Tabuk really need its floors and balconies waterproofed, and what will it cost? Tabuk sits about 762 m above sea level, and that elevation is part of why owners here ask the question. The reality is that the price of protecting a floor or balcony depends on the material chosen, and the facts we have for this work show a clear range. Bitumen membrane costs SAR 15–35 per m², spray foam costs SAR 25–35 per m², and epoxy coating costs SAR 35–85 per m². Crack injection, which is often needed on balconies where cracks have opened, is priced at SAR 40–115 per metre. Owners should compare these ranges against the area and condition of their own floors rather than choosing on price alone.

Our inspection starts with a walk over the floor and balcony surfaces to find cracks, low spots, and places where water has already stained the finish. The technician marks each crack and measures its length so the crack injection can be priced by the metre. Next, the surface is checked for the material that suits it, whether that is a membrane, a spray foam, or an epoxy layer, and the area in square metres is measured for each zone. Where the duplex has a roof or a bathroom with a similar problem, those areas are measured separately, since liquid roof waterproofing is priced at SAR 10–25 per m² and bathroom waterproofing at SAR 15–40 per m². The inspection ends with a written list of the zones, the measured areas, and the recommended materials, so the owner can see exactly what each part of the work involves.

Before the visit, the owner should clear the balconies and floors of furniture, plants, and stored items so that the technician can reach every edge and crack. It helps to gather any earlier records of leaks, repairs, or previous coatings, and to note where water has appeared inside the home after rain. If the duplex has a water tank, mention it at booking, because tank internal coating is priced at SAR 25–55 per m² and is often done in the same visit. Keeping access to the roof and the stairs open will also save time on the day. With these steps in place, the inspection can produce an accurate quote that matches the real condition of the floors and balconies.

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