Floor & balcony waterproofing for restaurants in Sakaka

Prepared by the technical team · editorial review · last updated 13 November 2026 · Sources

Before we start: what we know about Sakaka

The centre of Sakaka sits about 555 m above sea level (SRTM open elevation data). Team note on Sakaka: 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..

Picture a restaurant owner in Sakaka who has just opened a dining room with a rooftop terrace and a glazed balcony. The kitchen is busy, guests linger outside in the evening, and the first rain of the season leaves a damp patch spreading across the ceiling below. The owner wants the problem fixed before the next busy weekend, without closing the room for longer than necessary and without paying for work the building does not need.

The local setting matters. The centre of Sakaka sits about 555 m above sea level (SRTM open elevation data), so the town is on a plateau rather than a low coastal strip. For a restaurant owner this means the roof and balcony are exposed to strong sun by day and sharp temperature drops at night, and that repeated expansion and contraction is what opens hairline cracks in screeds and tiles. Rain, when it comes, tends to arrive in short, heavy bursts that test drainage more than the membrane itself. Any waterproofing plan should therefore start with the surfaces that take the most heat and water, and should expect movement at joints and cracks.

Work through the property in a practical order. First, walk the roof and balcony after rain and mark every crack, pooling area and failed joint. Second, decide the repair method by surface: crack injection is priced per metre at SAR 40–120 per m, while liquid roof waterproofing runs SAR 8–25 per m² and a bitumen membrane SAR 15–35 per m². Third, clear and dry the surface completely before any coating goes on, since moisture trapped under a membrane is the most common cause of early failure. Fourth, apply the system you chose, and where the balcony floor takes foot traffic from diners, consider epoxy coating at SAR 35–90 per m² for a harder wearing finish. Finally, ask for a written scope that lists each area in square metres, so you can check the quotation line by line against your own measurements before work begins.

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

Signs worth paying attention to

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

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

Where the problem usually comes from

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

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.
