I have a new construction and we are going to pour the driveway soon. I’d like to have a concrete driveway with a broom finish, but on the edges have a 1-2ft exposed aggregate border. Does anyone know how we can do this or how to setup the forms? I’m confused on how to setup the pour. Ideally, we’d like to do it all in one pour. Any help would be much appreciated.

i would make sure the concrete has the right agrgate, then pour the whole thing then when it is almost set up then use plywood on the concrete then make the inside of a border, standing on the plywood pressure wash border or use a garden hose and a wire brush using the plywood as a guide
You finish the concrete as usual andthen spray on a retarder o nthe 2 feet. next days spray off the concrete and the paste fraction will wash off where the retarder was exposing the aggregate.
