Equipment pad over existing pad
Equipment pad over existing pad
(OP)
I have an existing 5' X 10' X 4" pad that is too small. I don't want to have to chip it up to pour the new pad. The new pad will be about 6' X 20'. I plan on stippling the top of the old pad with a chipping hammer and coating it with an epoxy bonding agent. I need the finished pad to be at least 6" thick. Is 2" of concrete on top of the old pad going to be enough? Or should I make it thicker? Any other suggestions? The equipment going on the pad will weigh about 2,500 pounds.

No shortcuts, remove the existing and create a new pad.

Roughen the existing pad and applied bonding agent will help the performance. You can make it (6.5'x20') one placement, or leave the area over the existing pad for later using stronger/finer grout fill.
