Concrete Round Over - How to?

[Chems]

On our garage/workshop door there has been some pillars taken out over time and the concrete is broken and falling away, a right eye sore and we are currently replacing the entire drive (huge job its been!) one of the last jobs to do is to remove the concrete lip on the front and replace it with a nice one about 6 inchs further back.

We'd like to put something easy on the eye like a roundover, I feel that with a drier mix and a nice roundover mdf template to use as a float to shape it. Think like a sleeping policeman but one sided, about 6 inch height and depth to the quarter roundover.

Anyone got any top tips on how to sculpt concrete this way?

Piece of guttering cut down it`s length to give the desired radius, fixed rigidly to some shuttering & then a standard mix tamped in well.

A circular saw blade curf on the shuttering would give a rebate that would give a smooth transition from gutter to ply.

I second the guttering idea - I made a threshold for our garden path using this method to round over the facing edge and it worked a treat. Just make sure to tamp properlyto get a nice face!
