Before we start: what we know about Tarout

Main roads in or near Tarout: Uhud Road, Al Khaleej Road, Al Aimmah Bridge. Team note on Tarout: 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..

Tarout is about 0.9 km from the sea coast (OpenStreetMap). The centre of Tarout sits about 3 m above sea level (SRTM open elevation data).

Basement and foundation waterproofing for offices and commercial buildings in Tarout faces a problem that is common across the sector: water pressing from outside against below-ground walls and slabs, which then seeps through cracks, cold joints and wall-to-floor junctions. In an office or retail basement, even a small leak can damage stored records, electrical services and fit-out, so the first question is usually where the water is entering rather than how much area needs covering.

Tarout's location shapes the approach. The centre of Tarout sits about 3 m above sea level, which means the ground water table can sit close to the foundation depth, so hydrostatic pressure is a real factor and not a theoretical one. The town is also about 0.9 km from the sea coast, so the moisture and salt in the surrounding soil and air are worth taking into account when choosing materials. For basements, the price range for waterproofing runs from SAR 50 to SAR 150 per m², and the choice between systems matters. Bitumen membrane costs SAR 15–35 per m² and XPS boards cost SAR 12–30 per m², while epoxy coating runs SAR 35–90 per m². Where cracks are visible, crack injection is priced at SAR 40–120 per metre, so a surveyor should measure these before any area is quoted.

Before the visit, ask the provider to confirm whether the quote covers the whole basement or only the walls, whether the slab is included, and how cracks will be assessed and priced. Ask which system they propose for the water conditions near sea level, and whether they will check the drainage and ground levels around the building. Request a written breakdown by m² and by metre of crack so you can compare the figures with the ranges above. Finally, ask who will manage the work around your tenants' operating hours, so disruption to the office stays to a minimum.

For offices and commercial complexes, work is scheduled to avoid disrupting staff and visitors.

How the work is done, step by step

1. Finding the source: Groundwater, rain or a pipe — each needs a different treatment.
2. Preparation: Surfaces are cleaned and opened where needed.
