I did a full spray foam insulation when I built my house.. I have to say its damn near airtight and very sound proof still can hear redneck 4x4's go by but very faint.. My ceilings are 8" of spray foam with 18" of blown in (needs another layer settled to about 12").. I plan to ad geo eventually but not through the pond just underground horizontal undr my garden..

I believe in catch and release. I catch then release to the grease..
