Key Differences
A deck is often constructed as part of residential homes or buildings, typically made of wood or composite materials, and is used for leisure activities. On the other hand, a slab, particularly a concrete slab, is used as a foundational element in both residential and commercial construction, providing a sturdy base for buildings.
Decks are usually elevated from the ground and can be attached to a building or freestanding, enhancing outdoor living space. Whereas slabs are laid directly on the ground and are essential in creating a flat and stable surface for construction.
The construction of a deck involves framing that supports the decking material and requires considerations for load-bearing capacities. Meanwhile, slabs are poured as a single layer of concrete that needs to cure and is often reinforced with rebar or mesh.
Decks can include features such as railings, steps, and pergolas, designed for aesthetic appeal and safety. Conversely, slabs are generally not visible once construction is completed as they are typically covered by flooring materials or other structural elements.
Maintenance requirements for decks include regular cleaning, staining, or sealing to protect against the elements. In contrast, slabs require minimal maintenance once installed, but may need sealing or repairs if cracks develop.
