Residential Concrete Driveways and Paths

If you are after some definitive advice on the thickness of the concrete for a residential driveway slab, or what driveway slab reinforcement to use and how far apart crack control joints should be then you have come to the right place.

Check out this Residential Concrete Driveways and Paths manual produced by Cement Concrete and Aggregates Australia.

At Cornell Engineers we have been referring to this document since its release in 2006 and it’s still the best way to ensure satisfactory performance of your driveway slab.

The residential concrete driveway manual also has concrete driveway construction details.

Remember that in the absence of better information, this is the manual that will be referred to in the event of a dispute about uncontrolled cracks in your driveway.

Don’t forget local authorities (councils) have their own requirements for driveways, cross-overs and paths. For example, here is the link to the Driveway Technical Standards for Brisbane City Council:

We would love to design your driveway concrete for you. Please contact Cornell Engineers on 07 3102 2835.

If you have a cracked driveway slab, maybe we can help you. Call Matt Cornell for advice or to arrange an inspection.

Concrete Thickness for Commercial Driveways

Ask Cornell Engineers to design your commercial driveway . We’ll specify the concrete thickness, the strength of the concrete for your driveway.

Commercial concrete driveways are designed specifically for the  weigth of the vehicles usig the driveway, the number of times a day a vehicle uses the driveway and the ground conditions under the driveway.

Contact Cornell Engineers for more information.

Concrete Driveway Repairs

Oh no. Your concrete driveway has cracks in it. Cracks in a concrete driveway aren’t necessarily a bad thing but if your concrete driveway is brand new and you have concerns, Cornell Engineers can check to ensure your concrete driveway was constructed correctly.

Driveway Slab Reinforcement and membranes

Steel reinforcing mesh is used in driveway slabs to control the width and length of cracks in concrete. If the mesh is “walked in” or placed at the bottom of the concrete slab, it is ineffective and won’t control cracks. Ensure your mesh is correctly positioned when pouring by chairing it on bar chairs at 1000 x 1000 centres.

Does a Concrete Driveway need Black Plastic

I was also asked recently if driveway slabs need the black plastic membrane (200 micron polyethylene membrane) under them before pouring.

If you have the plastic on site, then I recommend using it. The purpose it serves is to prevent the dry ground sucking moisture out of the wet concrete. That moisture is needed by the cement powder in the chemical reaction called hydration. Don’t worry if your driveway slab has already been poured without the plastic membrane. Not having it won’t decrease your slab’s strength too much – especially if your concreter wet the ground before pouring.
