[Greenbuilding] Dry or DriCoreR+ for basement

[Sacie Lambertson]

All, I am delighted to see old names and a renewed interest in this group.
Thanks for responding, John.

We are watching nearly every nail applied to new construction next door.
Interesting to view new products I've never seen before.

Keep it up!!

Cheers, Sacie
