Before we start: what we know about Tabarjal

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

Will a bathroom leak in Tabarjal be fixed properly by a quick patch, or does the whole floor need attention? The honest answer depends on what the inspection finds, and in Tabarjal the first thing to understand is that the town's centre sits about 548 m above sea level, a setting that shapes how buildings are finished and how water moves through them. A bathroom waterproofing job is priced by the square metre, and the rate for this work typically falls between SAR 15 and SAR 40 per m². Where the problem is a hairline crack rather than a general failure, crack injection is priced per metre at SAR 40 to SAR 120 per m, so the scope of the repair should follow the damage rather than assumptions made from the outside.

The visit begins with a walk-through of the bathroom floor, walls and the junction where they meet, looking for cracks, lifted tiles, soft patches and staining on the ceiling below. The technician then matches the fault to a suitable system. A bitumen membrane, priced at SAR 15 to SAR 35 per m², suits many floor applications, while an epoxy coating at SAR 35 to SAR 90 per m² is used where a harder, more durable surface is wanted. Spray foam, at SAR 20 to SAR 45 per m², can be considered where it fits the substrate. The inspection notes which option matches the condition of the surface, and it records the measured area so the quote reflects real square metres rather than estimates.

Before the visit, clear the bathroom floor and the areas around the shower and sink so the technician can reach the joints and drains without moving heavy items. Note when you first saw the leak, whether it appears after showers or only after rain, and which room sits below the bathroom. Take photographs of any stains or cracks, and mention any previous repairs, since old sealant or tiles can affect how the new layer bonds. Having the bathroom dimensions ready, or a rough sketch with measurements, helps the technician confirm the area quickly. These simple steps let the inspection focus on the cause of the problem, which is the most useful starting point for any waterproofing decision.

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