Hi all,
just after a bit of clarification/knowledge before I contact my BI (ha's not very approachable)
I need to lay new waste through the extension floor slab.
I am not sure how is best to do this.
Do I lay the pipes at correct fall rate on 100mm bed or pea gravel, box it all in, do the rest of the floor then fill over all pipes separately?
Do I lay all mot type 1 and sand then dig out for pipe and fill with mot1 and sand again?
Or is there another way I should be doing it?
Thank you in advanced
