Interlocking pavers are more attractive and interesting than poured concrete slabs. They interlock with sand to allow for movement in the ground instead of cracking. After digging below them (like for a sewer repair), they can also be reinstalled without showing any sign that any work was done. They are great for small and difficult to access projects. Pavers are a versatile and economical alternative to natural stone. Like all concrete products, they can show stains, absorb oils, fade, and wear from rain and pressure washing. Many of our project managers and installers have taken classes from the Concrete Masonry and Hardscapes Association in interlocking paver installation (previously ICPI).
