you need to drill holes to the existing foundation at place, depth and diameter specified, fill the with epoxy resins and add the steel bar. Those bar will the be casted into the new concrete foundation connecting it to the existing.
There are very specific details of how and where they need to be installed depending on size of bars and strength required.
