hydraulic cement is what you want to use in an opening in concrete block
or cement wall.
not spray foam that is flammable and not UV protected.
(that would be the hackers way)





do it right
or just go back to sleep

filled and

Apparently

between the

them

on

something

sleeves

need to

busted

I was

can and

|
| I've got big but slender hands, so it's not a HUGE gap... probably
| something like two 3/4" copper pipes running through a rough 2"
opening
|

name of

the

could ask
