newbie with first question. Great site btw.
Just coming to the final stage of making the base for new oak frame garage. Foundations and block/brick work completed leaving huge hole (6m x 5m x 500mm deep) to fill before oversite. Is there an approx calculation for the weight to volume for hardcore? It's sold by the tonne but I only know the volume I have to fill. Also is it better to use crushed concrete rather than hardcore? Any help much appreciated.
