Installing a soil Pipe Through a half metre thick wall

[helenhismadwife]

Hi all

I am hoping that someone can give us some advice, we need to install a soil pipe and it has to go through a wall that is about half a metre thick

how do we drill through it, any advice on drilling through it would be greatly appreciated. We have been told that we will find it difficult to get someone in

to do such a small job

If wall is that thick, I assume that it is stone? If so, just use a hammer and chisel and/or a crow bar and prise the stones out one by one. The outer layer on each side is normally stuck together with anything but cement, so come out fairly easily - the layer between the two outside walls tends to be loose fill, so comes out very easily, as long as the stones are smaller than your hole.

You normally end up with a much biggerhole than you need, but trying to drill or cut the right size hole tends to break the stones and they fall out anyway.

Thats how it works here, anyway. Have just made about 20 such holes for the beams for our bathroom floor.

If it is solid stone as oppposed to stones laid together. Treat youself to an SDS drill and a decent bits and drill 6, 8 iir 12 holes round the circumference then link them up  with the SDS chissel. If it is stones work them out till you get the hole you need ideally chossing at place under a large stone to act as a lintle on both sides.
