Run with me on this post...I have poured in a mix of gravel and soil to fill the grooves of the corro to make a flat surface, the reason is I am putting in (cutting out) an "ash drop" so i need to layout the oven bricks to see where to cut through the corro BEFORE laying the concrete, what i will be doing is creating a hole/slot at the oven entry so I need to know now where that entry point will be.
For this I have done a mock layout of bricks and my dome template.
i won't explain these images now as it will be explained once i have done it.
I'll be leaving the gravel there as the concrete will absorb into it anyway thus creating concrete !
