Why bathroom waterproofing differs in Abu Arish

The centre of Abu Arish sits about 67 m above sea level (SRTM open elevation data). Team note on Abu Arish: 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..

Bathroom waterproofing in Abu Arish starts with a check of the ground the building sits on. The centre of Abu Arish sits about 67 m above sea level (SRTM open elevation data), which means a home here is not in a low-lying hollow where surface water collects, so the first question is usually how water moves through the bathroom floor and walls rather than how it pools from outside. Before any material is chosen, the technician looks at the existing tiles, grout lines and the junction between floor and wall, because these are where moisture most often enters a wet room. Pricing for the work is usually framed per square metre, with bathroom waterproofing typically in the range of SAR 15–40 per m², so the size of the room drives the quote as much as the product does.

Several things can only be settled on the site visit. The technician needs to see whether the substrate is sound, whether there are hairline cracks that require crack injection (typically SAR 40–120 per metre), and whether the shower tray, drain and pipe penetrations are in good condition. The choice between epoxy coating (SAR 35–90 per m²), spray foam (SAR 20–45 per m²) or a bitumen membrane (SAR 15–35 per m²) depends on how the room is used and how the existing surface looks, so it is not decided from a phone call. If the bathroom sits above another living space, the technician will also check the ceiling below for previous staining, because that tells them how long moisture has been moving through the slab.

To help the technician, have the bathroom clear and the floor exposed where possible, and note any past leaks, repairs or damp patches you have seen. Let them know whether the room has a shower enclosure, a sunken tray or a raised threshold, and whether anyone uses the space heavily. If there is a water storage tank nearby that needs internal coating (SAR 25–60 per m²), mention it so the visit can cover it too. Clear information at this stage lets the technician arrive with the right tools, avoid repeat trips and give you an accurate picture of the work before it begins.

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