I'm building a 3.5M tall climbing frame / zip wire platform in the garden and want to make sure the legs are well secured particularly given the height and leverage.
I have a lot of very heavy concrete blocks from a demolished outbuilding, would it be practical to dig a larger hole, throw in a bunch of these around the post and pour concrete over the lot? My thinking was that the concrete would glue the whole heavy mass together and create more resistance with less concrete used than just filling the hole directly with it.
