It's solid concrete.

If you decide to use the expansion bolts I’d recommend renting the giant drill and concrete bit from Home Depot if you can. I installed a deck once and the rental drill made installing the bolts a breeze.

The "giant" drill LaoWai is recommending is a Hammer Drill. Get the appropriate sized masonry bit for the anchors you'll be using when you rent it.

Minor nitpick, it's a rotary hammer, not a hammer drill.
Rotary hammer uses a special sliding bit called a SDS bit that moves back and forth. Only the bit moves. It also has a mode where it can hammer without spinning and use chisel bits for demolition.
Hammer drill uses a normal masonry bit in an adjustable chuck and has a mechanism in it to vibrate the entire chuck back and forth
Rotary hammer is really what you want for anything beyond just doing a couple 1/8" holes. Having both, a rotary hammer can do a 1/2" hole in a granite boulder faster than a hammer drill can do a 5/32" hole in brick.
Both are colloquially called "hammer drills" but you've got to make sure it's actually a rotary hammer and uses a SDS bit.
