What is specific about Unaizah for floor & balcony waterproofing

The centre of Unaizah sits about 667 m above sea level (SRTM open elevation data). Team note on Unaizah: 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..

Floor and balcony waterproofing for restaurants in Unaizah starts with the location itself. The centre of Unaizah sits about 667 m above sea level (SRTM open elevation data), so a technician arriving at a restaurant here should first check how water drains away from the floor and balcony rather than assuming the ground around the building will carry it off. Restaurant floors take heavy traffic, frequent cleaning with water, grease and spills, so the first checks are the condition of the existing surface, any hollow or drummy patches, and whether water pools after cleaning. Balconies and external terraces are checked for slope toward outlets and for the state of the upstand where the floor meets a wall.

Several things can only be judged on the day. The exact depth and extent of cracking, the moisture content of the existing screed, the state of drains and their connection to the membrane, and whether old coatings are bonding or lifting all need hands-on inspection before a method is chosen. Access to the kitchen side, the wet-prep area and any space beneath the floor also changes the work, and so does whether the restaurant can close for part of the day. Where a crack is moving or wider than the surface suggests, the technician should record its length and mark it on the floor, since crack injection is priced per metre and the true length is only known once it is traced. Any sign of water rising from below should be noted for a separate assessment rather than treated as a surface job.

To help the technician, the owner or manager can prepare a short list before the visit. Note where leaks have been seen, whether they appear after cleaning or after rain, and which rooms sit directly below the floor. Share any earlier waterproofing records, the type of finish currently on the floor, and the approximate area of each zone in square metres so that options can be compared fairly. Options that are commonly considered for these areas include liquid roof waterproofing at SAR 10–25 per m², bitumen membrane at SAR 15–35 per m², spray foam at SAR 20–45 per m², and epoxy coating at SAR 35–85 per m². Ranges depend on the surface and conditions found on site, so the final quote follows the visit rather than replacing it.

For restaurants, visits are planned outside service hours and recorded for the premises file.

Signs worth paying attention to

The following signs are worth checking before they grow:

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

Causes we see in the field

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

Tools and methods, and when we use them

From the first visit to the report

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.
