Team note on Samtah: 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.. Main roads in or near Samtah: Al-Turshiyah and Al-Najmiyah Road, Samtah.

Before any material is chosen for a floor or balcony in Samtah, the first thing checked is how the surface behaves in its setting. The centre of Samtah sits about 61 m above sea level (SRTM open elevation data), and the town is about 22.6 km from the sea coast (OpenStreetMap). Those two facts shape the work: the surface is not a coastal, salt-laden exposure, but it still faces hot dry months and occasional heavy rain, so the first check is simply whether water is sitting on the slab, draining toward the wall, or finding a route under the finish. Drainage falls, outlets, and the junction where a balcony meets the building are inspected before any coating is discussed.

Several things are left to the site visit, because they cannot be judged from a distance. The technician needs to see the actual condition of the concrete, whether there are cracks, whether old membranes are lifting, and how much moisture is already in the slab. The choice between a liquid roof system, a bitumen membrane, an epoxy coating, or a spray foam depends on what is already there and how the surface will be used. Crack injection is priced per metre, so the length and position of any cracks has to be measured on site. Where a bathroom or a basement is involved, the area is confirmed on the ground rather than estimated from a plan. Indicative ranges from our pricing reference are SAR 8–25 per m² for liquid roof waterproofing, SAR 15–35 per m² for bitumen membrane, SAR 35–90 per m² for epoxy coating, and SAR 40–120 per metre for crack injection, but the final figure follows the inspection.

To help the technician, it is useful to have a few details ready before the visit. Note the approximate area of the floor or balcony, any leaks seen during rain, the age of the existing finish, and whether the space is open to the weather or covered. If a tank or basement is also part of the job, say so, since tank internal coating is priced at SAR 25–60 per m² and basement waterproofing at SAR 50–150 per m², and these are separate scopes. Clear access to the balcony edge and to the drain outlets saves time. A short note of when the leak first appeared, especially whether it came with the first heavy rain before summer, helps the technician decide where to start.

Checks before summer and before the rain season catch problems while they are still small.

Tools and methods, and when we use them

The steps in order

1. Checking the falls: Where water collects and where it should go.
2. Details: Thresholds, drains and upstands.
3. Waterproofing: The layer is applied and protected.
4. Flood test: Tested before the finish goes on.
