Short answer: In Michiana's freeze-thaw climate, interlocking pavers outperform poured concrete because they flex instead of fracture. Concrete is one rigid slab, so when our clay soil heaves and our winters cycle above and below freezing dozens of times a season, it cracks — and a crack is permanent. Pavers move as a flexible system of individual stones, settle back in spring, and if a section ever shifts, we lift a dozen of them and reset it in an afternoon. That single dif

Summary Standard plastic edge restraints spiked into clay soil will heave and break apart during a Michiana winter, causing the outer rows of your patio to separate. We lock the perimeter of every paver project with a hidden, fiber-reinforced concrete bond beam because it permanently stops lateral movement. The concrete is troweled over the extended gravel base and halfway up the paver, remaining completely invisible while allowing grass to grow directly against the stone. Th
