Floor & balcony waterproofing for restaurants in Riyadh

Picture a restaurant owner in Riyadh who has just opened a dining terrace on the first floor, with a kitchen below and a balcony that guests use in the evenings. Within a year, staff notice damp patches on the ceiling under the balcony and a faint smell in the storeroom. The owner has no plan yet, only a worry that water is getting into the building where food is prepared and served.
The local facts matter here. The centre of Riyadh sits about 637 m above sea level (SRTM open elevation data), which means the city is on a high plateau rather than near the coast, so the main concern is not flooding from the sea but water that collects and moves through the structure itself. Balconies and floors that are exposed to rain and to daily heating and cooling can crack over time, and those cracks are the usual route for moisture into a commercial kitchen or dining room. Because a restaurant is busy and hygiene-sensitive, a leak that seems minor can quickly affect the space and the business.
A sensible sequence starts with a survey. Walk the balcony and floor surfaces after rain, mark every crack and damp mark, and check where water drains. Next, deal with cracks first, because crack injection is priced per metre at SAR 40–125 per m, and sealing them early prevents the larger repair that follows. For the balcony surface itself, compare options: liquid roof waterproofing at SAR 10–25 per m², bitumen membrane at SAR 15–35 per m², or epoxy coating at SAR 35–95 per m² where a tougher, easy-to-clean finish suits a food area. Where the space below is a storeroom or cold room, consider XPS boards at SAR 15–30 per m² as added insulation. Finish by re-checking the work after the next rainy spell and keeping a simple record of what was done, so future maintenance is planned rather than reactive.
For restaurants, visits are planned outside service hours and recorded for the premises file.
Signs worth paying attention to
These are the signs most often linked to floor & balcony waterproofing:
- Water passing from the balcony to the floor below
- A wrong fall towards the door threshold
- Damp under the light well
The most common causes
- A threshold without waterproofing.
- Incorrect falls — we check this before anything else.
- A blocked drain.
Tools and methods, and when we use them
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
From the first visit to the report
- Checking the falls: Where water collects and where it should go.
- Details: Thresholds, drains and upstands.
- Waterproofing: The layer is applied and protected.
- Flood test: Tested before the finish goes on.

Questions from Riyadh
What is the best thermal insulation material for a humid climate in the Eastern Province?
In humid areas, it is preferable to choose materials with low water absorption, such as extruded polystyrene or polyurethane foam, because they retain their efficiency in the presence of moisture. However, the final choice depends on the type of surface, the budget, and the contractor's recommendation after inspection.
What is the drying time for the floor before use?
The drying time varies depending on the system type, layer thickness, and site temperature. The installer will specify it within the scope of work.
Does detecting bathroom leaks require breaking tiles?
Usually not. Modern tools such as thermal cameras, electronic listening devices, and pressure testing pinpoint the source of a leak with high accuracy. If breaking is necessary, it is limited to the repair point only, after the location has been confirmed.

Practical notes for residents of Riyadh
- Prices are in Saudi riyals (SAR); the final price is confirmed after the inspection, before any work starts.
- Have access ready to the water meter, the tank hatches, the roof and the main valve; in apartment buildings the roof keys are often with the building guard (haris).
- If you rent, tell your landlord or building management before the visit and agree in writing who pays; the written report can be shared with them.
- Keep photos of the problem and of any earlier repairs — they help the technician compare before and after.
