Before we start: what we know about Rijal Almaa

The centre of Rijal Almaa sits about 2206 m above sea level (SRTM open elevation data).

The first thing checked on a basement and foundation job for a hotel or serviced apartment is where the water is coming from and how it reaches the structure. Rijal Almaa sits at about 2206 m above sea level, so the site team looks at ground slope, drainage outfalls and the condition of the existing foundation before any material is chosen. This matters because a basement that is wet on one wall often has a different cause from one that is wet across the whole floor, and the fix for each is not the same. Pricing for basement waterproofing is quoted at SAR 50–150 per m², a wide range that reflects how much preparation the surface needs before a membrane or coating can go on.

Some points can only be settled on the site visit. The technician needs to see the actual wall and floor areas, confirm whether cracks are active or dormant, and judge how much of the existing coating has failed. Crack injection is priced at SAR 40–120 per metre, so the length and depth of each crack change the cost and the method. Bathrooms, roofs and any water tanks in the building are assessed separately: bathroom work runs SAR 15–40 per m², liquid roof waterproofing SAR 8–25 per m², and tank internal coating SAR 25–60 per m². Whether a bitumen membrane (SAR 15–35 per m²), spray foam (SAR 20–45 per m²), epoxy coating (SAR 35–90 per m²) or XPS boards (SAR 12–30 per m²) suits a given wall is decided once the substrate and water pressure are known.

To help the technician, the property manager should have ready the building's age, any earlier waterproofing records, a plan showing the basement and foundation layout, and notes on when leaks appear, such as after rain or during high occupancy. Access to the basement, the plant room and the rooftop should be arranged in advance, and any areas used by guests should be flagged so work can be scheduled around them. Clear information at this stage lets the technician measure accurately, recommend the right system for each zone, and give the hotel a quote it can plan around.

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