Before we start: what we know about Alhait

The centre of Alhait sits about 980 m above sea level (SRTM open elevation data).

Alhait sits at the centre of the area at about 980 m above sea level (SRTM open elevation data), and that height shapes what a technician checks first on a school or warehouse roof and walls. Before any quote, the first look is at the roof and the upper walls, where exposure to weather is greatest, and at the state of any existing liquid roof waterproofing, which is priced in the range of SAR 8–25 per m². Bitumen membrane, quoted at SAR 15–35 per m², is also considered where it is already laid, since the choice between the two depends on what is there now. The technician notes the size of the roof area and any ponding, because these decide whether a single layer will do or the whole surface needs preparing again.

The points that cannot be settled from a desk are left for the site visit. These include the condition of the substrate under the roof, the thermal performance needed for classrooms or stores, and whether XPS boards, quoted at SAR 12–30 per m², are suitable for the wall build-up or the floor. Spray foam, at SAR 20–45 per m², is considered only after the visit confirms the surface and access. Cracks in walls are measured on site, since crack injection is charged at SAR 40–120 per metre and the length cannot be estimated accurately from a plan. Basement waterproofing at SAR 50–150 per m² and tank internal coating at SAR 25–60 per m² are scoped only if those areas are part of the building and their condition is seen in person.

To help the technician, it is useful to have the building plans, the roof age and any previous repair records, and a note of where water has been seen entering. Tell the team which rooms are occupied during term time, because work will be planned around the school day. For warehouses, give the stored goods and any ventilation or loading-bay details. For epoxy coating, quoted at SAR 35–90 per m², mention the floors that take heavy traffic. Clear access to the roof and to any tanks or basement areas saves time on the visit and lets the technician give a more accurate scope.

For schools, the larger jobs are planned for weekends and holidays.
