i used mathoid as a packer an also made sure every stump had at least one on there as it is also a dampcourse, i was helped with a mate that is a re stumper an that is what they use in the trade, as for larger packers i was told to use different thickness of cement sheet, the new guy inspector wasnt to keen an wanted a structal engneer report i called a few an they all said it was fine to use but they would of recomened sum plastic cant remember what type it was but isnt a cheap plastic, so thats what is what sits on top of my stumps is mathoid ant caps then cement sheet packers where required,
