Floor & balcony waterproofing in Tabarjal: the local context

Team note on Tabarjal: 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.. The centre of Tabarjal sits about 548 m above sea level (SRTM open elevation data).

Is a leaking floor or balcony in Tabarjal something you can fix without tearing up the whole slab? In many cases, yes, but the right method depends on what is actually failing. Tabarjal's centre sits about 548 m above sea level (SRTM open elevation data), and our floor and balcony work is priced by the square metre and by the metre of crack, so the cost tracks the size and type of the problem rather than a flat fee. Balcony and floor treatments in this scope include epoxy coating at SAR 35–90 per m², spray foam at SAR 20–45 per m², bitumen membrane at SAR 15–35 per m², and crack injection at SAR 40–120 per metre. Bathroom waterproofing, often part of the same floor, is listed at SAR 15–40 per m².

The first step is an inspection of the surface and its edges. The technician walks the floor or balcony, marks any hairline cracks and checks where the surface meets walls, drains and door thresholds, since water usually travels along these joints before it shows on the ceiling below. Cracks are measured in metres so the quote reflects the real length to be injected. The area is measured in square metres, and the team notes whether the existing finish is tile, screed or concrete, because that decides whether the membrane can bond or the old layer must be cut back. Moisture is checked with a simple reading, and any ponding after rain is recorded. Based on these findings, the technician recommends one method or a combination, and explains the price range that applies to each part of the job.

Before the visit, clear the balcony or floor of furniture, plant pots and loose items so the surface can be walked and measured in full. Note where you have seen water: near the wall, under the door, or on the ceiling below, and when it appears, whether during rain, after washing or all the time. Photos of stains and of any cracks you have noticed are useful. Make sure the drain outlets are reachable and that someone who knows the property can give access. If you already know the approximate size of the balcony or floor in square metres, write it down, since it speeds up the estimate. Having this ready means the inspection can focus on the source of the leak rather than on finding it.

Each job ends with a written report that carries a verification code you can check on our site.
