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..
Riyadh's climate is dry and hot for most of the year, with intense sun that can raise surface temperatures well above the air temperature, and bathroom floors here often sit on older concrete slabs that have been exposed to repeated heating and cooling. Because of this, the surface prep stage matters as much as the membrane itself. Before any coating goes down, the team needs to confirm what sits under the existing finish and how the slab has aged, since a sound base is what allows the waterproofing to bond and last.
For a bathroom or balcony floor in this city, the first things checked are the condition of the concrete, any cracks or hollow areas, and the slope toward the drain, because standing water is the most common cause of leaks in wet rooms. Costs for this work are usually quoted per square metre, with bathroom and balcony floor insulation typically falling between 15 and 40 riyals per square metre, while a protective or reflective topcoat adds roughly 10 to 30 riyals per square metre. Where the existing slab is old, the scope may need extra preparation, and the team will explain that before work begins instead of after.
Before the visit, it helps to clear the room, note any past leaks or stains, and gather details of the previous finish, such as tiles or paint. Ask the team how long the floor must dry before it can be used, whether epoxy can be applied over the existing concrete in your case, and if the floor is near a cold storage area, whether an epoxy finish is suitable for that use.
Each job ends with a written report that carries a verification code you can check on our site.

Common questions about bathroom waterproofing in 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.
