Advice required re digging channel into concrete

[Jules-and-Boo]

Hi - I am laying some pipes and need to cut a channel quite deep - maybe 40-60cm but only wide enough for a pipe.

What do I need?

I thought a grinder to cut the edges and then a hammer drill?

But I'm not sure the drill bit will be long enough.

So, I thought I'd ask the EDFers before I go and get things I don't need or won't do the job.

You will know, this is not my area or skillset.

I want to assess the difficulty and tools required before I decide if I need to get someone (other than boyfriend and his mate) in.

Thanks :-)

Hi,

I would use an angle grinder to make a channel each side of where the pipe is going then use a hammer drill with a chisel bit to remove the section of concrete you need.

You will find that it will come up easy with the hammer drill after you have made the channel

Or you can use a comb chisel and hammer
