Question
Hi, Mr. Cummings,
Is the expansive grout something I could find at a local hardware store?  Is it something I could find at a specific type of store?  (I live in Louisville, KY).  Thank you.

Answer
I doubt you can find this specialty material at ordinary retail stores.  The yhave trade names like damite, dexpan, bristar, CS Kim capsule, FractAG.  Here is one link that gives a little more information.  http://rebar.ecn.purdue.edu/ect/Civil/soundche.aspx

You might start with Daigh Chemical.  http://www.daighcompany.com/ourPeople.asp
