What is specific about Tabarjal for basement & foundation waterproofing

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

Picture the owner of a small serviced apartment building in Tabarjal. Guests arrive, the lobby looks smart, and the rooms are full most of the year. Then one morning the housekeeper finds damp patches along the lower wall of the basement store, where linen and spare furniture are kept. The owner has no wish to shut rooms or disappoint guests, so the question becomes how to deal with the water quickly and without a costly rebuild.

The local setting matters here. The centre of Tabarjal sits about 548 m above sea level, which means the ground is not a flat, low-lying bowl where water collects, but the site still has to shed rainwater and manage groundwater pressure against below-ground walls. For a hotel or serviced property with a basement, that combination makes wall and floor sealing a practical priority rather than a cosmetic one. Basement waterproofing typically falls in the SAR 50–150 per m² range, so the owner should first measure the affected area accurately, then decide whether the work is a full basement treatment or a targeted repair of cracks and damp zones.

A sensible order of work starts with a site survey: walk the basement after rain, mark every damp patch and crack, and note where water enters. Next, repair active leaks by crack injection, which is priced at SAR 40–120 per metre, so long cracks should be measured in advance. Then address the surfaces themselves, choosing between bitumen membrane at SAR 15–35 per m², epoxy coating at SAR 35–90 per m², or spray foam at SAR 20–45 per m² depending on the wall condition. Bathrooms and roof areas should be handled in parallel, using bathroom waterproofing at SAR 15–40 per m² and liquid roof waterproofing at SAR 8–25 per m². Finally, schedule works outside peak occupancy and inspect the basement after the next heavy rainfall to confirm the repair holds.

For hotels and serviced apartments, rooms are handled in batches to keep units available.
