Anyone on here a contractor/ engineer/concrete pad specialist haha ( not 100% sure what their actual title is... ) or know a person who not only finishes it smooth once its poured but knows what is required/how to add to a existing cement pad. Needs to be added on to a side, back and then added on top of the current pad as well to make it higher and bond the new with the old properly! Making one large new pad :) Quotes?
