Floor and balcony waterproofing work for hotels and serviced apartments in Jubail starts with the site's location. The centre of Jubail sits about 4 m above sea level (SRTM open elevation data), and the town is about 0.9 km from the sea coast (OpenStreetMap). Because of this closeness to the coast, the technician checks first how moisture and salt-laden air may already have affected the existing surface, including any staining, efflorescence, or lifting at tile joints and balcony edges. Drainage paths, outlets, and the falls of the slab are also looked at early, since standing water on a balcony or in a wet area is where most leaks begin.

Some points can only be settled on the site visit. The technician will need to see the actual condition of the substrate, whether cracks are active or stable, how the drains and upstands are built, and whether the floor below is occupied by guests, which affects how long the area can be closed off. The choice between systems such as liquid roof waterproofing, bitumen membrane, epoxy coating, spray foam, or crack injection depends on those findings. Where a balcony or wet area sits over occupied rooms, access, noise, and ventilation during curing are also agreed on the spot, along with the sequence of work so that daily operations of the property are disturbed as little as possible.

To help the technician prepare, the property team should share the age of the slab, any previous waterproofing records, and the rooms affected by each leak report. Photographs of stains, a note of where water collects after rain, and the floor plan showing balconies and bathrooms all help. Indicative ranges that the team may see in quotations include bathroom waterproofing at SAR 15–40 per m², liquid roof waterproofing at SAR 8–25 per m², and crack injection at SAR 40–120 per metre. These ranges are only a starting point; the final scope is confirmed after inspection.

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