After a very long layoff over the Autumn and Winter I have finally made some progress on the saga of the shed. Over the last couple of weeks I've cast the last of the walls which define the outside of the workshop floor slab. Over the weekend I fitted and mortared in the 110mm pipes that will form ducts between the pit/machine room and the workshop proper and I glued 50mm thick polystyrene foam to the walls. On Tuesday I fitted a damp proof membrane, a
100mm layer of polystyrene foam and another damp proof membrane. Today, with the aid of a lorry mounted pump, I laid 6m^3 of fibre reinforced concrete. I have a floor for my workshop, 50 weeks and 3 days after I started work :-). It still needs one more going over with the power float to finish smoothing it off, but that'll be done tomorrow.Mark Rand RTFM
