Why basement & foundation waterproofing differs in Tabarjal

The centre of Tabarjal sits about 548 m above sea level (SRTM open elevation data). Team note on Tabarjal: 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..

A restaurant owner in Tabarjal often runs a busy kitchen on the ground floor and keeps storage, cold rooms and dry goods in a basement below. Water that seeps through a wall or floor slab can ruin stock, damage equipment and force a closure at the worst possible time. Because the owner is also managing staff, suppliers and inspections, a leak below the dining room is usually discovered only after it has already caused damage.

The centre of Tabarjal sits about 548 m above sea level, which is a useful reminder that the site is not at the coast and is not low-lying. Even so, a basement is below ground whatever the elevation, and soil moisture and surface runoff still press against its walls. For a restaurant, the practical meaning is that waterproofing should be planned as part of protecting the business, not treated as a cosmetic fix. Costs vary with the method, so an owner should compare options against the area that needs protection, from basement walls at SAR 50–150 per m² to crack injection at SAR 40–120 per metre.

Work through the steps in order. First, have the basement and any cracks inspected and mapped so that you know the total area and the exact length of visible cracks. Second, decide on the main method for the basement envelope, such as a bitumen membrane at SAR 15–35 per m² or an epoxy coating at SAR 35–90 per m², and check whether the storage area will need XPS boards at SAR 12–30 per m² for insulation. Third, seal any active cracks by crack injection before the surface coating goes on, so that new cracks are not trapped beneath it. Fourth, if the basement holds water storage, consider a tank internal coating at SAR 25–60 per m². Finally, schedule the work outside peak trading hours and keep a written record of the completed areas for future maintenance.

For restaurants, visits are planned outside service hours and recorded for the premises file.

Signs worth paying attention to

Where the problem usually comes from

• A common cause: cracks at construction joints.
• Rainwater draining towards the foundation — we check this before anything else.
• A common cause: a high groundwater level.
