Concrete Overlay
Concrete Overlay
(OP)
We have a small (150ft) length of roadway that is being used as a wet crossing. It is a 12" culvert will the 150ft length of concrete driveway pured over top of it. We want to raise this roadway max 2' and install 2-15" culverts. Before concrete is poured on old concrete is a bonding agent normally needed?

IMHO, bonded overlays are a nightmare - I would not use them unless the overlay has to be "thin". In fact, for a small project, I would consider removing the existing concrete and replacing it with new instead of using a bonded overlay... but that is just my opinion (based on experience).
