Then there are RedHeads. A bolt and anchor system. Nice and strong,

You use a hammer-drill and make the appropriate size hole into the
slab. Then you drop in aan epoxy-filled glass tube, then the anchor
bolt. You smack the anchor bolt with a hammer, breaking the epoxy
tube. Twenty four hour cure.

Come back next day, lay sill plates and go....

This is interesting and I want to learn more about it. I went to the
Red Head Anchoring System web site

http://www.ramset-redhead.com/rh_as_intro.asp

and found many types of anchors but no mention of the drop-in epoxy
tube. Please elaborate. Thank you.
