Hi there,
I have a wooden playground removed from a preschool I am restoring & wanting to put up in my yard for my children. It consists of 6 90x90mm posts, and two standing platforms that are 1.2m square it also has a steel ladder, large steel climbing tube (3m) & steel fence section with a steering wheel all of which form part of the stability for the structure. The posts are above ground & were bracketed in at the original location.
My question is can I use otter stirrup ground screws to secure to the ground, rather that a concrete & bracket solution? This is more attractive as long-term allows for easy removal/moving if ever required. NZ user so soil is softer in winter, silt mix. As an aside the house is on piles & didn’t require any additional depth piles etc on construction, the ground was deemed stable.
