IFTTT, reddit Busting up 4 in slab Posted by diyer on February 5, 2021 Tomorrow I’ll be demoing out a 4 in (unreinforced) slab. My question Is wether to use a jack hammer, sledge hammer or chemical concrete breaker.Edit: sledge hammer will be handy but not the primary breaker. via /r/DIY https://ift.tt/39NkrLB
