what would you guys use to put a hole in a block foundation for a 3/4 inch black plastic water line.
thanks RICK

if it is just block then a hammer will knock a hole in it, try to make sure you hit between the core s on the block, you can use a large chisel to also helo make the hole, just go easy, or you can go rent a hammer drill with a 1-1/4 bit and drill it, remember to seal the hole up with either a silicone type stuff of hydraulic cement

hammer and a piece of 1" steel pipe or equivelent if I didn't have a hammer drill and bit big/long enough..... Just don't pussyfoot around and jar everything. Hit hard & solid and you'll be thru quick....

You only need a star drill and a hammer.

If tour talking "cinder block" its pretty soft, breaks quite easily. i dont think i'd go at it whit a hammer and bar or you might end up with a much larger hole than you want. that said i dont think you'll need a hammer drill either if you dont have one, regular drill and concrete bit should work easily enough. course if block has been concrete filled where your drilling a hammer drill would be an asset.

Best answer.

I would use a hammer. Install the water line in a 1.5 pvc sleeve with a Fernco on both ends to keep ground water out. The sleeve will protect the water line going through the block. Use hydro. cement to seal the block.

Make your hole larger than needed. Especially if you're crossing an area you expect to backfill. Then, use a piece of schedule 40 pipe from the inside of the wall to virgin soil, and seal it with quik set mix. Pass your water line through it, and seal it with expansion foam. If the soil settles in later years, your water line won't pinch off and break, and you'll have a ready hole in the block if you need to work on it at a later date.

Is the block still hollow or has it been filled with cement? The easiest and best way to make a hole would be to use a hammer drill with a 1" masonary bit. Be careful if you are going to use a hammer. If the wall is hollow you can end up with a hole big enough to put your arm through.

Masonry hammer drill would be my second choice, you just have to be careful once you penetrate into the block cell, you could hit a cell wall too, you will know quickly, masonry bits punch through block or concrete masonry units (CMU) very easily unless its high strength cmu.

Not too long ago I had to re-route a sump pump discharge line for my neighbor, through a hollow CMU foundation wall, a good friend who is a hvac/plumber, had a core bit set in his truck, I borrowed that and over sized the hole for a pvc sleeve and sent the sump discharge line through that, core bits do provide a neater hole, the masonry hammer bit could fracture or spall the opposite side, either will work, one may require a little patching. For larger holes, in CMU or concrete core bits are commonly used.

Star drills are in the same class of tool as burlap condoms.
