Floor & balcony waterproofing in Aldarb: the local context

The centre of Aldarb sits about 79 m above sea level (SRTM open elevation data). Aldarb is about 18.7 km from the sea coast (OpenStreetMap).

Is a leaking office floor or balcony slab a problem we can fix without shutting the whole building down? In Aldarb, the answer depends on where the water is coming from and how far it has travelled. The centre of Aldarb sits about 79 m above sea level, and the town lies roughly 18.7 km from the sea coast, so commercial owners here are dealing with a dry, inland site rather than the salt-laden conditions found right on the shore. What matters most is the condition of the existing layers, the presence of cracks, and whether the water is rising from below or entering from above. Our floor and balcony waterproofing work for offices and commercial complexes starts with that diagnosis, so the chosen system matches the actual problem rather than a generic guess.

Our inspection begins with a walk-through of the affected floor or balcony to map damp patches, staining, blistering and hairline cracks. Where cracks are found, we measure their length so that crack injection can be priced per metre, which is typically SAR 40–120 per m. Surfaces are then checked for the type of finish already in place, since epoxy coating (SAR 35–90 per m²) and spray foam (SAR 20–45 per m²) each need a sound, clean base to bond properly. Balconies and roofs are assessed separately, because liquid roof waterproofing (SAR 8–25 per m²) and bitumen membrane (SAR 15–35 per m²) suit exposed areas differently from interior floors. For any water-storage tanks serving the complex, the internal condition is reviewed as well, with tank internal coating priced at SAR 25–60 per m². Each area is recorded so the proposed scope is clear before any work is agreed.

To make the visit productive, please prepare a few basics in advance. Gather any previous waterproofing records, maintenance reports or drawings showing the floor build-up, and note where and when leaks first appeared and whether they worsen after rain or use. Clear access to the affected floor, balcony or roof, and let your facilities team know which areas are used daily so that work can be scheduled around office hours. If a basement is involved, basement waterproofing (SAR 50–150 per m²) is priced separately, so mention it early. Having this information ready helps us give you a clear, itemised estimate for your Aldarb property.

For offices and commercial complexes, work is scheduled to avoid disrupting staff and visitors.
