Can a leaking floor or balcony be fixed in Khobar without tearing up the tiles? Many owners here assume the only option is demolition, but the reality is more flexible. Khobar's centre sits about 9 m above sea level, and the city is roughly 1.8 km from the sea coast, so moisture and salt can still reach floors and balconies over time. Where the water is coming through, the right repair depends on the surface, the crack pattern and how much of the floor is affected. Crack injection, priced at SAR 40–120 per m, can seal a hairline leak from the top side, while spray foam at SAR 20–45 per m² and liquid roof waterproofing at SAR 10–25 per m² can cover larger areas without lifting finished surfaces.
Our inspection starts with a walk over the floor or balcony to map where water sits, where cracks run and how the drainage falls. The technician then checks the joints at walls, drains and door thresholds, because these are the usual entry points. Next comes a moisture check on the surface and the neighbouring areas, so the repair covers the full leak path rather than only the visible patch. Based on what is found, the technician recommends a method and gives a clear per-metre or per-square-metre scope, using the ranges above: epoxy coating at SAR 35–90 per m², bitumen membrane at SAR 15–35 per m², or XPS boards at SAR 10–30 per m² where insulation is also needed. Nothing is sealed until the owner has seen the findings and agreed the scope.
Before the visit, clear the area around the floor or balcony so the technician can reach joints, drains and the edges of tiles. Note when the leak appears, whether after rain, after showering or all the time, because this helps narrow the cause. Have any previous repair records or plans ready, and tell the technician about any cracks you have already noticed. If the leak runs under a bathroom or into a basement, mention that too, since bathroom waterproofing is priced at SAR 15–40 per m² and basement work at SAR 50–150 per m². Keep access to the unit open during the inspection, and plan for the technician to spend time on the site before any work begins.
The aim is to locate the cause with instruments first, so any opening is limited to one point.

| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
The steps in order
- Checking the falls: Where water collects and where it should go.
- Details: Thresholds, drains and upstands.

Questions from 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?
