Why bathroom waterproofing differs in 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..

Does a bathroom in an apartment in Tabarjal really need waterproofing, and what will it cost? Tabarjal sits about 548 m above sea level, and that height is a useful reminder that every building here is exposed to its own local conditions, so the right approach starts with what is actually happening in your bathroom. For bathroom waterproofing in apartments, the typical rate quoted is SAR 15–40 per m², and the price moves with the materials chosen. Spray foam falls at SAR 20–45 per m², epoxy coating at SAR 35–90 per m², and a bitumen membrane at SAR 15–35 per m². If there are visible cracks in the floor or walls, crack injection is priced at SAR 40–120 per metre, so the cost of the repair itself can differ a lot from the cost of the finished surface.

The inspection begins with a walk through the bathroom to look for staining along skirting boards, soft or blistered tiles, grout that has darkened, and any cracks running through the floor or the wall corners. The technician then measures the floor and wall areas so the work can be quoted per square metre, and notes any cracks by length in metres so they can be priced separately. Where the apartment sits above another unit, the condition of the ceiling below is checked for damp patches, since leaks often show up in the unit beneath first. Moisture is tested in the walls and floor, and the findings are written down so you can see exactly which areas need treatment and which can be left alone. This step decides which material suits the surface rather than applying one product everywhere.

Before the visit, clear the bathroom floor and the area around the shower, sink and toilet so the surfaces can be reached easily. Note when you first noticed any damp, staining or cracking, and whether it gets worse after rain or after the shower is used, since that history helps the technician find the cause. Keep the access route to the bathroom clear, and let the person who manages the building know if the upstairs or downstairs neighbour may need to be contacted. Having these details ready will make the inspection quicker and the quote easier to compare.

In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.
