Thanks so much both, Makes things much clearer now. Re. The ‘foam wrap’ - do you recommend a particular thing to use for this? Many thanks,

Hi Russell, Many thanks for your response. Fully understand your points re. bedding the rest bend and pipe in with concrete (was aware of this). I may not have explained my point clearly but what I was asking was once all of the bends and pipes are concreted in, when the solid floor build up is being installed (type 1, sand, cement, insulation, screed) … what is the process around the remaining neck of the rest bend and pipe? Do you build the floor up as normal around it or does it need to be shuttered off? Many thanks

Evening All, I just had a quick question regarding some underground 110mm drainage I am installing in my property. Currently I have excavated the entire ground floor in preparation for a 450mm insulated solid floor build up. As part of a full property renovation, I am laying new 110mm underground drainage. My question is regarding the back filling aspect for the rest bends of the drainage. The rest bends are 300mm in height. I understand the back filling element of the pipe runs needs to be in pea shingle as coverage, but what about the fill up to the crown of the rest bend? Is it a case of building the floor up as normal around the rest bend (type 1, sand, concrete etc) or should a full depth of pea shingle be used as backfill up the entire height of the rest bend (compacted) with a screed finish? Many thanks in advance
