I'm raising and levelling a 4 metre square sloping site (16m sq) using chalk excavated from another area of my garden. (its waste chalk I would otherwise have to find a home for)
The chalk fill will increase from approx 0.4 metre at the top of the slope, to around 1 metre at the bottom of the slope, and the long term plan is to patio it.
I know I need to consolidate the fill, but by how much? Do I need to layer it approx 15cm deep and compact it and then repeat? Or do I just heap it up, walk about on it a bit and then compact the top layer?
I would hire a wacker plate but I want to layer it in stages as we are still digging out the other part of the garden, which means buying would probably be cheaper, plus its a long term thing that I suspect we'll be doing for several weeks. But at £250, are cheap wackers any good? Petrol or electric? I have a punner (heavy square foot on a pole) that I can use to compact it, would a cheap wacker be much faster/more effective or should I just stick with the punner?
