Frequently Asked Questions
How thick should a concrete driveway be?
Residential driveways should be 4 inches thick. For heavy vehicles, use 5-6 inches. Always install over 4-6 inches of compacted gravel base.

Wire mesh or rebar is recommended for driveways to prevent cracking. Use 6x6 wire mesh or #3 rebar on 18-inch centers.
