These modular construction components, typically concrete or stone, are available at major home improvement retailers. They serve as fundamental elements for constructing retaining walls, garden borders, and various landscape features. For example, a homeowner might use these blocks to create a raised flower bed or to terrace a sloped yard.
The use of such building units offers several advantages, including ease of installation compared to poured concrete, design flexibility, and durability against the elements. Historically, similar building materials have been employed for centuries in various construction projects, demonstrating a long-standing need for easily manageable and structurally sound components in both residential and commercial applications. Their availability at large retail chains democratizes access to landscape construction materials, enabling wider participation in outdoor improvement projects.
