Anchoring a child`s swing in shallow ground (7" depth) Feasible?

[Paul Morrell]

Morning All, I have a child`s swing to anchor (metal tubular frame) for my granddaughter. Unfortunately, the potential site has only around 7” depth of earth with a concrete base / platform below. Could anyone please advise, is anchoring a swing feasible in such shallow ground? and what would be the best method / approach? Thanks in advance

If the legs come with a hook and length of rod - maybe you could drill into the concrete and put the rod in the hole and use a resin to fix . Otherwise you need to break out holes in the concrete and go down the use postfix concrete.

what is the concrete? An old shed floor? Or the covering over drains or something?

The one you can safely drill; the other you can't.

If you can drill it, I'd consider setting stainless steel studding into it, positioned so the feet of the swing will sit on top and be retained with a stainless nut (anything other than stainless will quickly rust, so it will be difficult to remove when redundant, and will lose its strength and safety.

Stainless studding can be be bought cut to your needs, and is not very expensive in small amounts. I use it for garden work like gates and fences, and to hold down my carport legs. You can get a special anti-seize lubricant for the threads.

+1 for stainless steel threaded bar. Can't ever have too much stainless steel in one's life. Peace of mind.
