Hi all Built a SB a few years back - with a bit of help from some of the good folks here ... :-) Psyching myself up for another one and revisiting many of the thoughts/notes compiled last time round. I used rammed tyres and railway sleepers as a foundation last time. Recently I had cause to hire a small digger to get a polytunnel project started and I was impressed with the hire rate/work achievable with it. In short I reckon a digger/trench/rubble foundation could well knock the rammed tyre foundation into a cocked hat wrt time. I don't live in an earth-quake zone Coupled with a compressor/sprayer for mortar application on the walls it seems the 2 main time consumers could be dramatically reduced. Anyone have experience of rubble and tyres? Got a comparison? I presume sleepers could still fit between rubble/stone and straw? Would this be a good insulator?
