Do warehouse floors and balconies in Aldawadmi need waterproofing, and what does it cost? The centre of Aldawadmi sits about 976 m above sea level, and that matters for how a building's floors, slabs and balconies are exposed to weather and runoff. Surfaces that are not sealed can take in water, crack and lose their finish over time, which is why property owners here tend to plan a protective coating or membrane before problems appear rather than after. For the most common options, the work is priced per square metre: epoxy coating runs SAR 35–90 per m², spray foam runs SAR 20–45 per m², and bitumen membrane runs SAR 15–35 per m². Where a floor has visible cracks, crack injection is priced per metre at SAR 40–120 per m, so the cost depends on how much of the surface is affected.

A site visit begins with a walk across the warehouse floor and every balcony or external slab to look for cracks, damp patches, worn coating and areas where water pools. The inspector notes the length of any cracks, since crack injection is measured by the metre, and records the total area of each surface, since the other methods are measured per square metre. Roof areas are checked separately, because liquid roof waterproofing is priced at SAR 8–25 per m² and is often the first thing to examine where water enters a building. The inspector then recommends a method that suits the surface, whether that is a membrane, a coating, a foam layer or a combination, and explains the reasons for each choice in plain terms.

Before the visit, gather the building's drawings or a rough plan with dimensions, so the floor and balcony areas can be measured quickly. Note any past leaks, repairs or areas where water collects after rain, and take dated photographs if possible. Make sure the inspector can access the roof, balconies and any storage areas that are normally locked, and clear the floor so the surface can be seen properly. Having these details ready lets the visit focus on the surface itself, and gives you a clear basis for comparing the quotes that follow.

For warehouses, work is phased around operations and stored goods.
