straw bale project at Joes slide show on Flickr
The yard is full of gravel so we are using that for footers and the soil has a lot of clay so we are using that for cob.
The Straw bales are spiked with rebar down in to the gravel footer, then sewn together with bailing wire to bond the whole structure together. All the gaps and seams are packed with chips of straw or loose straw.
Core form of straw bales is anchored and sewn together ready for cob.
