I need to finish the foundations for my dwarf-walled Victorian conservatory (measures approx 2.5m x 2.5m) by laying 100mm of concrete and would like some advice as I want as smooth a finish as I can get. I have already put down 150mm hardcore, 30mm sand blinding, a layer of visqueen, insulation and now just need to get the concrete sorted.
For various reasons the conservatory has already been built around the base, which I know wasn’t the best order in which to do things but I’m unsure about how to finish it off as all the walls are already up. Do I still need to use shuttering to contain the concrete? How do I tamp it given the conservatory base is like a hexagon, 2.5m deep and the walls are up so I can’t walk around the outside? What’s the best way of smoothing it off?
I’d really like to get this right first time so would very much appreciate any advice on how to go about doing this! Thanks
