Floor & balcony waterproofing for apartments in Riyadh
In short: In Riyadh (Riyadh), floor & balcony waterproofing for apartments begins with the roof, falls and drains survey and the moisture meter for ceilings and walls; nothing is opened until the position is clear. The centre of Riyadh sits about 637 m above sea level (SRTM open elevation data). Pricing starts from Bathroom waterproofing (per m²) (SAR 15–40 per m²), and other items are quoted after the visit.
Why floor & balcony waterproofing differs in Riyadh
Team note on Riyadh: 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.. Main roads in or near Riyadh: King Fahd Road, King Abdullah Road, King Abdullah.
The centre of Riyadh sits about 637 m above sea level (SRTM open elevation data).
The most common problem with floors and balconies in Riyadh apartments is water getting under tiles where the screed has cracked or where the membrane was never properly bonded to the slab. Balconies are especially exposed because rainwater pools at the threshold and seeps into the unit below, and bathroom floors that sit above a neighbour's ceiling can leak for months before anyone notices the stain. Crack injection is often needed first, priced at SAR 40–125 per m, before any surface system is applied.
The local conditions shape the approach. The centre of Riyadh sits about 637 m above sea level, so buildings face strong sun and wide temperature swings rather than heavy coastal humidity, which means the surface system must tolerate expansion and contraction as well as water. For a wet area such as a bathroom, bathroom waterproofing at SAR 15–40 per m² is usually the starting point, while a balcony or open terrace may suit liquid roof waterproofing at SAR 10–25 per m² or a bitumen membrane at SAR 15–35 per m². Where a flat roof sits above the apartment, spray foam at SAR 20–45 per m² or XPS boards at SAR 15–30 per m² can add insulation alongside the waterproofing. Epoxy coating at SAR 35–95 per m² is used where a hard, easy-clean finish is wanted, and basement waterproofing at SAR 55–160 per m² applies only if the unit sits below ground level.
Before the visit, ask the provider to confirm which area is being treated and whether the leak source has been traced, since surface work alone will not fix water coming through a crack. Ask which system they recommend for that exact surface and why, and request a written breakdown of the rates that will apply, such as the per-m² rate and any per-metre charge for cracks. Ask how the existing tiles or screed will be prepared and whether protection will be needed for the flat below. Finally, ask what the work will involve for your daily routine, so you can plan around the site and the rooms you need to use.
In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.

How we choose the tool in Riyadh
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
How the work is done, step by step
- 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.

Short answers for 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.
