Compare pavers vs concrete for cost, lifespan and more

Pavers vs concrete: strength and longevity. Concrete is very strong, but it's prone to cracking and staining over time (although stamped concrete is better at hiding stains). You might eventually have to remove the entire slab when large cracks and damage appear. Pavers can be up to four times stronger than concrete slabs and take up to four
