How to pour concrete for curved walkway to prevent cracking?
Curved concrete drives and walkways are no more likely to crack than rectangular. I have a semi circular drive and a curved walk. The drive foundation was well packed and it has 1/2 rebar on roughly 18' centers ( we had some left over from the house) , it has handled 10,000+ lb. trucks, no problem . The walk, not so well packed and used only mesh : It has hairline cracks at some decorative brick inlays. So with good preparation and rebar you can make any shape you want.
