Can't claim the insight as original but, how is a VB still a VB once
you've punched it full of holes?<br>
(Just nit picking - on the side of goo.)<br>

fastening. Screw vs Goo, if you will. Without being responsible
for the installation personally, I am more comfortable spec'ing
mechanical fastening. I'm thinking to fasten the lams of plywood
at 8" centers EW, and secure it to the slab with flathead tapcons
at 24" OCEW, with 3/4" embedment. <br>

A remaining question is resistance of the foam to insect
infestation. This suggests a rugged vapor barrier over the
slab--as for insect supression as for vapor migration. (in this
case the basement is well drained, with little risk of significant
bulk water anywhere.)<br>
