Key takeaways
- Four inches is common for cars
- Heavier loads call for more thickness
- The base matters as much as the slab
- The Rebar Grid Planner shows steel layout
A driveway looks simple, but what is under it decides how long it lasts.
Thickness
A common thickness for a passenger-vehicle driveway is about four inches. Trucks, trailers and heavy equipment call for more.
The base
A compacted gravel base keeps the slab from settling and helps water drain. It is the part you will never see and always feel.
Steel and joints
Reinforcement and well-placed control joints help control cracking.
