I need to get two new water pipes into a basement room. Outside the room, there's a "chest" with a walkway/balcony on top, so it's not possible to dig it out.
There is an existing 40 mm PEM pipe through it.
I was wondering if it would be possible to "drill" through with a 110mm pipe if I use the existing PEM pipe as a "guide." The chest seems to mostly contain sand and smaller stones.
Do you think it's possible to get a thicker pipe in somehow?

Take an iron pipe (approx. 100mm diameter) and cut one end so you get 2-3 large "teeth", on the other end attach a crossbar as a handle then you should easily be able to drill/strike your way through the coffin.
