Before we start: what we know about Abha

The centre of Abha sits about 2230 m above sea level (SRTM open elevation data). Team note on Abha: 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..

Do bathroom floors in Abha really need a check if they still look dry? Many owners assume that a bathroom with no visible leak is sound, yet water can travel through hairline gaps and reach the rooms below long before a stain appears. Abha sits at the centre of a city about 2230 m above sea level, where the climate and the age of many buildings mean that the sealing layer under tiles can weaken quietly over time. A periodic preventive check is the simplest way to catch that early, and bathroom waterproofing work in the city is priced at SAR 15–40 per m², so a small repair found in time costs far less than a full redo.

The inspection begins with the surface. The technician looks at tile joints, silicone seals around the bath or shower tray, and the edges where the wall meets the floor, since these are the points where water most often gets in. Next, the floor is checked for cracks and any sign of soft or hollow areas that suggest water has spread under the finish. Where a problem is suspected, crack injection is priced at SAR 40–115 per metre, and spray foam or epoxy coating may be discussed as options for the affected zone, with epoxy coating at SAR 35–85 per m² and spray foam at SAR 20–45 per m². The technician then notes the condition of the drain and the slope toward it, because poor falls cause standing water that slowly tests the membrane. The result is a written summary of what is sound, what needs watching, and what should be treated.

Before the visit, clear the bathroom floor and the space around the tub or shower so the seals and joints can be seen clearly. Move bath mats, toiletries and any loose items, and make sure the drain is free of hair and debris. If you have noticed damp patches on a ceiling below, a musty smell, or tiles that sound hollow when tapped, write these down and point them out to the technician, along with the date you first saw them. Keep any earlier repair invoices or waterproofing records for the property, as they help show what work was done and when. Arrange access to the flat or room below if the check involves that area, and confirm whether you or a tenant will be present so questions can be answered on the spot.

Preventive checks follow a written schedule instead of waiting for a fault.
