What is specific about Alrass for basement & foundation waterproofing

Main roads in or near Alrass: King Abdulaziz Road, King Fahd Road, King Salman Road. The centre of Alrass sits about 695 m above sea level (SRTM open elevation data).

Team note on Alrass: 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..

An owner of a rest house or farm in the Alrass area often has a basement, a storage room, or a lower level that sits below the ground outside. Over time, water can seep through the walls and floor, leaving damp patches, a musty smell, and stored goods at risk. Many owners only notice the problem after the first wet season, when the damage is already visible and the repair becomes more involved.

The local facts matter here. The centre of Alrass sits about 695 m above sea level, which places it on higher ground. That elevation does not remove the need for protection, but it does mean the work should be planned around how water actually moves across the land and into the structure. For a basement, the main cost is typically in the membrane or coating applied to the walls and floor, which is priced at SAR 50–150 per m². For a farm building with lower walls, the scope may be smaller. Cracks should be sealed as part of the same plan, as crack injection costs SAR 40–120 per metre, so finding and recording them early keeps the budget clear.

A sensible approach starts with a careful inspection of the lower walls, floor, and any cracks, followed by a note of the total wall and floor area in square metres. Next, decide which protection suits each area: a bitumen membrane at SAR 15–35 per m² or an epoxy coating at SAR 35–90 per m² for surfaces that need a hard finish. Seal the cracks first, then apply the chosen system, and allow it to cure fully before backfilling or storing anything. If the roof of an outbuilding also leaks, liquid roof waterproofing at SAR 8–25 per m² can be added to the same schedule. Finally, check the work after the next rainfall and keep a simple record of what was done, so future repairs are quicker and better informed.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.
