Many contractors are venturing more and more into pouring slabs. Virtually guarantees no call backs.

The purpose of unit pavers is they float with the heaving in the winter, where as concrete does not, hence their cracked exposed aggregate.

The compacted aggregate base is the same method all highways and roads are built on. Whether asphalt or concrete - it's placed over compacted aggregate.
