Floor & balcony waterproofing in Dammam: the local context

Team note on Dammam: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins.. Dammam is about 4.3 km from the sea coast (OpenStreetMap).

The centre of Dammam sits about 12 m above sea level (SRTM open elevation data).

An owner of a hotel or serviced apartment building in Dammam usually manages several floors of guest rooms, shared corridors and a large balcony area, all of which must stay dry for guests to be comfortable. The first leak often appears in a bathroom below a balcony or on a corridor ceiling, and by then water may have spread through the structure. The owner's priority is to protect guest rooms with as little disruption to bookings as possible, which means planning floor and balcony work in stages rather than closing the whole building at once.

The local facts matter here. The centre of Dammam sits about 12 m above sea level, and the city is about 4.3 km from the sea coast. Those figures mean the site is close enough to the coast to be exposed to salty, humid air, yet high enough that the ground does not sit in standing water in the way low coastal land might. For an owner, this suggests that balcony drainage and the junction between floors and walls need careful attention, because the damp coastal air will find any weak point. Since balconies and bathrooms are the most common sources of leaks in this type of building, the owner should budget for those areas first and use the price ranges as a starting guide: bathroom waterproofing at SAR 15–40 per m², liquid roof waterproofing at SAR 10–25 per m², and epoxy coating at SAR 35–90 per m² for surfaces that need a hard-wearing finish.

A practical order of work begins with a survey of every floor, marking damp patches, cracks and failed sealant on a plan of the building. Next, crack injection is priced at SAR 40–120 per m, so sealing active cracks should come before any surface membrane is applied. Third, choose a surface system for each area: a bitumen membrane at SAR 15–35 per m² for balcony slabs, or spray foam at SAR 25–35 per m² where a seamless layer is needed. Fourth, treat bathrooms and corridors in sequence so that only one floor is out of service at a time. Finally, arrange a flood test and a documented inspection before the area returns to guest use.

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

Signs worth paying attention to

If you notice one of these signs in Dammam, it is a good moment to talk to the team:

• Damp under the light well
• A wrong fall towards the door threshold
• Water passing from the balcony to the floor below

Causes we see in the field

• A blocked drain — we check this before anything else.
• A common cause: incorrect falls.
• A common cause: a threshold without waterproofing.

Tools and methods, and when we use them

How the work is done, step by step

1. Checking the falls: Where water collects and where it should go.
2. Details: Thresholds, drains and upstands.
3. Waterproofing: The layer is applied and protected.
4. Flood test: Tested before the finish goes on.
