How thick should concrete be for a driveway?

Question

We're having a new concrete driveway laid. The tradesmen we have hired mentioned different thicknesses depending on vehicle weight. What's the minimum depth that we can get away with to save money?

Steven · Answer

The minimum thickness of it depends on what concrete mix and additives  (fibreglass,steel ect ) but I would get a minimum of 10cm

David · Answer

for a safe thickness would be 4 inch or 100mm, this would accommodate all vehicles

Victor · Answer

You can only get away with less thickness if you put re bar in ,I wouldn’t recommend it going on less than four inches probably a bit more, honestly your best paying for a decent thickness it will only cost you more in the long run , but I think the installer should know not to put it any less than recommended! 
I’d keep an eye on the thickness don’t save money now or you’ll pay more later!
Good luck 👍

To be really safe i would say 100mm at least then I would even put some steel reinforcement in it.

Your paying to have a new driveway, so it needs to be done right.

Cutting corners to save money on a driveway installation especially when installing concrete as it has a tendency to crack under frequent use and also suffers from ground movement. My advise would be never accept anything less than 100mm we always prefer to install 150mm as a minimum depth with expansion joints and reinforcing if your budget would allow .

Good Morning, 
Here is the answer to your question, the Minimum is 4 Inches (100mm) with a sub base of 100mm - 150mm (4-6 inches).

We install our concrete driveways at 125mm (5 inches) that’s our rule of thumb this covers small - medium sized vehicles, but the highways recommend minimum depth for a concrete driveways  is 4 inches and 3 inches for a path or patio.

Hello have they explained that for  strength, you best lay  reinforcing mess in the concrete pour me myself would put a depth of  5/6 inches , 2, inches first then lay 4,inches  of concrete  for your final layer, you can have the mix made up with   Fibres,  in the mix for added  strength,  All goes on what you can  afford,  please be carefull  allow for Subbase, before concreting,

Depending on the weight of your vehicle 5 inches is just about the bare minimum you can lay
