The distinction between driveable pavers and non-driveable pavers is essential when planning the layout of an outdoor surface, such as a driveway, a patio, or a pedestrian path. Understanding this difference allows for the appropriate material to be chosen based on the intended use, thereby ensuring the durability and functionality of the layout.
Definition and Use
Driveable paver: A driveable paver is specifically designed to support the weight and traffic of vehicles. It is used for driveways, parking lots, and any other area where vehicles may circulate. The design of these pavers takes into account the need to withstand heavy loads and the repeated impacts of car tires.

Non-driveable paver: Non-driveable pavers, on the other hand, are intended for areas where traffic is limited to pedestrians or light non-motorized vehicles, such as bicycles. They are commonly used for patios, sidewalks, garden paths, and other pedestrian spaces. Their design emphasizes aesthetics and comfort underfoot, rather than resistance to heavy loads.
Materials and Composition
Driveable paver: The materials used for driveable pavers are chosen for their robustness and ability to withstand high pressures. High-density concrete pavers and natural stone pavers, such as granite and basalt, are popular choices due to their exceptional durability. These pavers are often thicker and harder than non-driveable pavers, allowing them to withstand the forces exerted by vehicles.

Non-driveable paver: Non-driveable pavers can be made from a wider variety of materials, often at a lower cost. Lightweight concrete pavers, reconstituted stone, ceramic, or composite wood are commonly used. These materials, while less robust than those used for driveable pavers, offer a great variety of textures, colors, and styles to meet the aesthetic needs of pedestrian spaces.
Thickness and Dimension
Driveable paver: The thickness of driveable pavers is generally greater than that of non-driveable pavers. They typically measure between 6 and 8 centimeters thick, or even more, to ensure adequate resistance to heavy loads. Additionally, the dimensions of these pavers are often standardized to facilitate an even distribution of loads.
Non-driveable paver: Non-driveable pavers can be thinner, often around 3 to 5 centimeters thick. This thickness is sufficient to support the weight of pedestrians and light gardening equipment. The dimensions can also be more varied, allowing for more creative patterns and arrangements.
Installation and Sub-base
Driveable paver: The installation of driveable pavers requires more rigorous soil preparation. A solid and well-compacted sub-base is essential to ensure the durability of the layout. This often involves the use of crushed gravel and sand to create a stable and well-drained base capable of supporting the dynamic loads of vehicles.
Non-driveable paver: The installation of non-driveable pavers is generally simpler and less costly. A less thick and less compact base may suffice, as the load support requirements are lower. However, it is still important to properly prepare the soil to avoid drainage and stability issues.
Cost and Maintenance
Driveable paver: Driveable pavers, due to their robustness and higher preparation requirements, are often more expensive to purchase and install. However, their durability can reduce long-term maintenance costs. They also require regular maintenance to prevent the accumulation of dirt and the growth of weeds in the joints.
Non-driveable paver: Non-driveable pavers are generally less expensive and easier to install. Their maintenance can also be simpler, although they may require more frequent repairs if installed in areas subjected to heavier loads than expected.
