Deck footings - sub base

[Scabutz]

Im building a small deck 4.5 x 3.8 m I plan on using those plastic adjustable footings to support the frame. The ground is soil, but been there for years and heavily compacted. Should I dig it out and put some hardcore down and compact it or will the footings be ok straight on the soil? Will lay weed membrane down first.

Yeah that’s a pain. Hardcore compacted down should be alright on its own but it’s not ideal.

Is postmix short on supply as well?

Yeah. Wicks, B&Q, Toolstation, all the builders yards, none of them local have any postcrete. Tell a lie one of the stores in Hitchin 40 miles away has 1 bag.

Looking again the drop from the patio door is quite far and I think posts probably are needed to raise the height a bit.

Bizarrely some builders merchants have bulk postmix in stock and even reduced. Just ordered 80 x 20kg bags for just over 300 notes delivered. Probably more than I need but can sell the rest and at a massive mark up.
