I'm adding a shed on the side of my garage.
It works out that the new concrete floor level will just nicely line up with the top of one of the existing concrete steps into the garage - makes a nice reference point for the levelling.
However the existing step has quite a 45 deg. bevel on it's leading edge. Do I need to treat this in any way to get the new concrete to bond to it ? My concern is that if the bond isn't reasonable, the new concrete will break away in time as it is potentially a weak spot.
Thanks
Rob
