All cements based fillers shrink shruggy I've used Moroso block filler once and it shrank away from one freeze plug after it pushed it out enough to need replacing shruggy
I've heard that "Hard Block" brand filler is a epoxy filler and doesn't need to cure 30 days and it doesn't shrink also confused I also heard it does expand and shrink shruggy I haven't used it so I don't know about it either way shruggy
