Why floor & balcony waterproofing differs in Sharurah

Team note on Sharurah: 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.. The centre of Sharurah sits about 724 m above sea level (SRTM open elevation data).

Is it worth waterproofing the floors and balconies of a school in Sharurah, and what does that actually involve? For most property owners the answer depends on how the building is used and how it has aged. Sharurah sits at about 724 m above sea level, and a site at that height with heavy daily use, long hot spells and sudden rain puts real stress on concrete surfaces. Floors and balconies that take foot traffic, furniture moves and cleaning water need a membrane or coating that stays sealed under that wear. Our pricing for this work runs from SAR 35–90 per m² for epoxy coating, SAR 20–45 per m² for spray foam, and SAR 15–35 per m² for a bitumen membrane, so you can compare options against the surface and the budget before any work starts.

Our inspection begins with a walk of every floor slab and balcony to note cracks, ponding spots, old coatings that have lifted, and the edges where the floor meets walls and drains. Where cracks run through the slab, we measure their length, since crack injection is priced per metre at SAR 40–120 per m, and mark them for treatment. We check the balcony falls to confirm that water drains away from the building rather than pooling against the door frames. Each area is then recorded by its square metreage, so the surface type, the chosen system and the expected cost per m² are set out clearly for the owner to review. Nothing is sealed until the surfaces have been examined and the findings explained.

To make the visit run smoothly, please clear the floors and balconies of furniture, planters, and stored equipment so the inspector can reach every edge. Tell us which areas are used most, such as corridors, play areas and outdoor balconies, and whether any space was waterproofed before and what happened to it. Share the building drawings or a rough plan with room sizes if you have them, and let us know the school's operating hours so work can be scheduled around classes. Keep any earlier repair records to hand, and make sure a responsible staff member is available to let the inspector in and answer questions on site.

For schools, the larger jobs are planned for weekends and holidays.
