Before any product is chosen for a duplex floor or balcony in Khobar, the first check is location. The centre of Khobar sits about 9 m above sea level, and the city is about 1.8 km from the sea coast. Those two facts shape the work: the ground is not at the waterline, but the nearness of the coast means salt-laden air and humidity are constant concerns, so surfaces exposed to weather need coatings that can handle both moisture and salt. The technician should note the slope of each balcony and whether rainwater drains away from the building, since a flat or back-sloping balcony holds water against the slab edge and invites leaks into the unit below.
Several things are deliberately left to the site visit and cannot be judged from a distance. The condition of the existing slab, the width and depth of any cracks, the presence of old bitumen layers, and whether a previous coating is lifting or blistering all need to be seen in person. The same goes for the state of drainage outlets, the height of the upturn at the wall junction, and whether a bathroom sits directly above a living space. Each of these decides which system is suitable, and the final quote for a floor or balcony is only firm once the technician has walked the area and tested the surface.
To help the technician prepare, the homeowner should share the age of the duplex, any past leak history, and photographs of stains or cracks on the ceiling below. Note which rooms are below the balcony or bathroom, and whether the roof above is accessible. Clear access to the balcony, the roof and the unit below on the day of the visit saves time. A short written description of when leaks appear, such as only during heavy rain or after washing, gives the technician a useful clue about where water is entering.
In a duplex, the two floors often share lines, so tests are done floor by floor.

Common questions about floor & balcony waterproofing in Khobar
Can the roof be insulated over the existing insulation layer?
This depends on the condition of the old layer. If it is intact and stable, a new layer may be applied. If it is damaged, it must be removed. A technician will determine this after inspection.
What is the best type of roof waterproofing for Khobar's climate?
The choice depends on the surface and its use. Bituminous rolls and liquid polyurethane coatings are common for exposed roofs to resist heat and humidity, while cementitious materials suit tanks and bathrooms. The contractor determines the best type after inspection.
What is the best type of roof waterproofing in Al-Khobar?
