Interlocking is a widespread choice for any part of property landscaping. It can be used for Driveways, Walkways, Porches, Patios, Retaining Walls, etc. The advantage of interlocking is that over time, it can be re-levelled and withstand changing climates, which would take a toll on concrete and asphalt surfaces. There is never a worry about cracking or sinking and of course you can save yourself a bundle avoiding repairs, as re-levelling is inexpensive in comparison.
