Is it an emergency if water is coming through your floor or balcony in Riyadh? Often it is, and the sooner you act, the less damage water can do to the slab, the tiles and the rooms below. The centre of Riyadh sits about 637 m above sea level, so the city is set on high inland ground, but that elevation does not protect a leaking balcony or a damp floor slab from rain, irrigation runoff or old, failed membranes. Our service covers floor and balcony waterproofing for urgent cases, and the first step is always to confirm where the water is really coming from.
Our technicians start with a site inspection. They walk the floor or balcony, check the drainage outlets and the junction where the floor meets the wall, and look for cracks, blistered surfaces and areas that hold standing water. Where a crack is the cause, the usual repair is crack injection, which is priced at SAR 40–125 per metre. For wider failed areas, the team recommends a suitable system and gives a price per square metre. Bitumen membrane runs SAR 15–35 per m², epoxy coating runs SAR 35–95 per m², and spray foam runs SAR 20–45 per m². Liquid roof waterproofing sits at SAR 10–25 per m², and XPS boards at SAR 15–30 per m². Bathroom waterproofing, where the leak starts from wet areas, is SAR 15–40 per m². The inspection tells us which of these fits your surface and your leak.
Before the visit, please clear the area so the technician can reach the floor edges, drains and balcony railings. Note when the leak appears, whether it follows rain, washing or the use of a bathroom above, and take photos of any stains or cracks. Switch off nearby electrical outlets if water is near them, and move valuables and furniture away from the wet zone. If the leak affects a basement, tell us so we can quote basement waterproofing at SAR 55–160 per m². Having these details ready helps us diagnose the problem faster and start the repair sooner.
If water is flowing, close the main valve first, then call or message with photos.

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.
