I've been clearing a raised slab area so that the ground can be levelled and existing slabbing extended. As I was doing this, I came across this pipe. At first, I thought it was copper because of the noise it made when tapped, how cold it felt and even the look of it.
I had inadvertently made a few holes prior to realising this was here.
So it turns out that it's the pipe for the waste water collected from the guttering on our garage, it comes down and goes from right to left and straight under the garage. It's right in the way of us maximising the slabbing area and I don't know why it was designed like this to come out from underneath and then go back under.
Within the holes I made, there are signs of fibres. They look to me much like glass fibres you get within coarse fibreglass (not the stuff in insulation).
So I want to lower the hole for the drainpipe so it's much closer to the level of the other slabs and also want to try and keep it out of the way if possible. What are your thoughts?
