Breaking through cinder blocks

I have to run an exhaust pipe through the cinder blocks of my foundation, i will need to chip away approximatly half of one brick. Any tips on doing this ?

drill many

small (1/4") holes close together where you mark the penetration, using a masonary drill bit. try to locate it in the hollow cavity of the block, if the hole is small enough. then knock it out a little at a time. get a beauty ring to go around the pipe against the block.

rent a Bosch demolition hammer with a breaking bit. It will go through that wall quickly. Wear safety goggles. Make the hole big enough for the pipe!

If these are hollow cinderblock, then a 16 oz claw hammer will work fine.

If they are poured full of concrete, or if they are solid cement blocks, you'll have to do Mr. Smith's method.

Hey Peg, pounded any sand lately?

Why, just the other day I was priviledged to have an electric jackhammer handy and pounded some sand right on up some guy's orifice! Thank you for asking!
