Floor & balcony waterproofing in Alula: the local context

The centre of Alula sits about 697 m above sea level (SRTM open elevation data). Main roads in or near Alula: King Abdullah Road.

Does a leaking office floor or balcony slab always mean a costly rebuild? Usually it does not, and the facts show why. Waterproofing for floors and balconies in commercial buildings is priced by the square metre, with liquid roof waterproofing at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², and epoxy coating at SAR 35–90 per m². Where a leak is confined to hairline cracks, crack injection is charged per metre at SAR 40–120 per m. Choosing the right system depends on the surface and how it is used, not on a single fixed approach. Projects in Alula, where the centre sits about 697 m above sea level, are assessed on the same basis as anywhere else, with the surface condition deciding the method.

Our inspection begins with a walk over the affected floor or balcony to map where water is entering and where it is pooling. The team checks the slab for cracks, the junctions with walls and drainage outlets, and the condition of any existing coating. Where cracks are active, they are marked and measured so the length can be priced per metre. Areas of wider damage are measured in square metres so the surface can be calculated against the unit rates. The inspection also notes whether the surface sits under a finished floor, a tiled balcony or an exposed roof, because each changes the preparation and the material chosen. At the end of the visit, the findings are set out clearly so you can see which areas need attention and why.

Before the visit, gather a few details that speed up the assessment. Note where the leaks appear, especially after rain, and how long they have been happening. Have the building's drawings or as-built plans available if you hold them, showing slab areas and drainage positions. Clear access to the affected floor or balcony so the surface can be walked and measured without obstruction. If previous repairs or coatings were applied, record the product name or contractor's notes if you have them. Tell us whether the area is in regular use, since this affects when work can be scheduled around tenants and daily operations.

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