Update 4 - Concrete!

Concrete pours are always stressful and this was no exception, although we got a nice technical rep. in to support us with the Self Compacting Concrete (ie self-levelling - magic!) as a promotional freebie, the lorry was late and almost got stuck the wrong side of a parked car... But once cured the concrete will form a solid, flood resisting floor that will add to the thermal mass of the building, smoothing temperature fluctuations. The concrete came with steel fibre reinforcement (chopped up wires) that meant we didn't need a reinforcing steel mesh, saving time, money and aggravation (and injuries!).
