I'm reviewing a drawing where a new pedestal just 2 feet in height, 1.5' sqaure, is connecting to an existing slab on grade. Horizontal shear on pedestal is less than 3 kips. Drawing is asking to roughen existing and use bonding adhesive. Pedestal rebar will be doweled in using hilti epoxy. The use of bonding adhesive the I want to question in this case.
In case of new spread footing, pedestal is poured after footing hardens but no bonding adhesive is used.
