What is specific about Aldarb for floor & balcony waterproofing

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

A typical owner in Aldarb might have a ground-floor flat with a small balcony, or a villa with an open terrace above a living room. Water usually shows up as a damp patch on the ceiling below, a bubbling tile near the balcony door, or a grey stain running down a wall after rain. The owner wants to know what the work costs, whether the quoted rates are fair, and how to avoid paying twice for the same fix.

The local facts shape that decision. The centre of Aldarb sits about 79 m above sea level, and the town is about 18.7 km from the sea coast. That means the area is inland and not especially low-lying, so standing water after storms is less likely to be the main cause of a leak than cracks, failed sealant, and worn membranes on the balcony surface. For a floor or balcony job, the practical price range depends mainly on the system chosen. Liquid roof waterproofing is listed at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², and spray foam at SAR 20–45 per m². Epoxy coating, which suits sealed balcony floors that need a harder finish, is listed at SAR 35–90 per m². If the leak runs along a joint or hairline crack, crack injection is priced at SAR 40–120 per metre, so it is worth finding the crack before choosing a whole-area system.

Start by walking the balcony after rain and marking every wet line, crack, and drain outlet. Next, check whether the damp appears only at the edges, which often points to sealant or upstands, or across the whole surface, which points to the membrane itself. Then ask each supplier to price per square metre for the same system, and to state separately the cost of crack injection and drain repair. Compare the quotes using the published ranges above rather than a single headline figure. Finally, confirm the surface preparation, drying time, and warranty terms in writing before work begins, and schedule the application for dry weather so the new layer cures properly.
