The front basement walls on my ranch were covered with fake stone
veneer, which, or course, was riddled with termite pathways.
I've removed most of the cast concrete "stones", and the front of the
hose looks a bit less attractive..

Is anyone aware of a lighter alternative that can be applied with a
tough mastic or construction adhesive? I feel that applying new
ones with mortar invites voids due to incomplete spreading, or ones
opening up later due to thermal expansion.

I suppose another alternative is to seal the top edge only, and
install a termite guard flashing along the bottom edge a few inches
above ground level..
