Is my balcony or floor slab due for a waterproofing check, and how do I know before water shows up inside? Riyadh is a dry city, but a few facts matter for planning. The centre of Riyadh sits about 637 m above sea level (SRTM open elevation data), and the work we describe here focuses on the floors and balconies of homes and buildings across the city. A periodic check is a low-cost habit: it looks for early signs of wear so that repairs stay small and targeted, rather than becoming a larger job after leaks reach the ceiling below.
The inspection follows a clear order. First, the technician walks the floor and balcony surfaces and looks for hairline cracks, lifted edges, blistering, and ponding after rain or washing. Where a crack is found, it is measured and recorded, because crack injection is priced per metre, typically SAR 40–125 per m, and the length determines the scope. Next, the technician checks the drainage points, the junctions with walls, and any area where the existing coating has peeled. For surfaces that need a new layer, the options are compared by type and area: epoxy coating at SAR 35–95 per m², spray foam at SAR 20–45 per m², liquid roof waterproofing at SAR 10–25 per m², and bitumen membrane at SAR 15–35 per m². The report then states which areas are sound, which need attention, and what each option would cost for the measured area.
Before the visit, gather a few simple things so the check is productive. Have the floor plan or a rough sketch with balconies and roof areas marked, and note any spot where you have seen damp patches, stains, or cracks. Tell the technician which areas are used for water storage, because a tank internal coating, priced at SAR 25–65 per m², is assessed separately. Clear furniture and plant pots from the balcony so the surface can be seen, and keep access to the roof hatch or stair open. If the building has a basement, mention it in advance, since basement waterproofing is priced separately at SAR 55–160 per m². With this information ready, the visit can focus on what matters and give you a clear, written picture of your property's condition.
Preventive checks follow a written schedule instead of waiting for a fault.

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.
