A finishing element for landscape construction, these units are designed to provide an aesthetically pleasing and protective top surface to structural boundaries. These products are typically manufactured from concrete, stone, or composite materials, offering durability and resistance to weathering. An example includes a concrete block shaped to fit securely on top of a segmented concrete wall, providing a smooth, uniform appearance.
The inclusion of these elements is important for several reasons. Primarily, they protect the underlying structure from water infiltration, which can lead to erosion and structural damage over time. Additionally, they enhance the visual appeal of the overall landscape design, creating a finished, polished look. Historically, similar elements have been used in construction for centuries to provide both protection and ornamentation.
