Drop in anchors. Drill the hole a little deeper than the anchor, blow it 
out and use the set tool to ram the plug down. If the tool won't go down to 
the shoulder don't worry I haven't had them come loose.  Firm blows with a 
lump hammer. Use the longest bolt possible to get as much bite as you can. 
You can't remove these easily afterwards.
You can split concrete slabs (Unintentionally) by putting a few of the 
larger ones in a row and setting them all the way
