How much postcrete per swing leg?

Eldi_Dos

Until we see the bottom of the swing legs it is open to interpretation as to method of installing.

But if you did want to concrete in ground screws it is not hard to do. Dig hole not too deep,insert ground screw, fill hole with concrete to suitable depth.

Whether it is a suitable method is open to debate though.

Thanks I have found a company who will do this but they said that they won't use the swing anchors but will use post crete and set that around the frame. But sounds like some others  have read on the comments not to do it that way?

I wouldn't go with that idea. The swing would be set down much lower, and would be harder to remove. 
I'd dig out he holes, set the swing in place and attach the anchors and concrete them in. Have the concrete low enough for the top of the anchor to be below ground level, so it can be covered with the lawn.

Thanks I was asking about this with the company and they said 

"Ground screws are not meant to be concreted in. Where are you reading this. I've been in building trade for 24 years. I build garden rooms, full structures and either the sub frame is concreted in or ground screws. Ground screws will never take to postcrete as someone would need to sit and hold it till the postcrete sets and also as it's so so small it would just come loose. So it would either be postcrete or the groundscrew. Also, the swing frame is an A-Frame for a reason. The wide footprint of the frame and the downwards force means the swing cannot move. If your wanting someone to install the groundscrews and concrete I'm afraid you'll need to get someone else as I can't sit and hold individual groundscrews in postcrete till it sets"

What are peoples thoughts ? 

They're right.  You wouldn't concrete in a ground screw.

Ground screws vary in length - From 500mm up to 2500mm (longer, available on request). Even a short one will have substantial holding power and doesn't need concrete. Indeed, using concrete defeats one reason for using ground screws - Namely being able to move them around.

You don't need to concrete ground screws, as they are designed not to need it.
However you need to concrete certain types of ground anchors. It depends what type you have.
The logical method is to dig out the holes, set up the swing with the anchors attached and then concrete them in. No need to hold the anchors in place.
Alternatively use ground screws.

I helped someone put in 4 groundscrews for a double swingset and playhouse with slide. Two went in fine but we couldn't get the other two in because we kept hitting builder's rubble just below the grass. Ended up digging big holes and burying the screws under the same rubble.
We realised they'd never screw out, but he's sold the house now, so we'll never know if or how it gets moved!

That swing looks like it could work without the legs being secured at all.  if it were me, I would erect it and try it out gently, to see how stable it is. 

I have not seen the ground anchors it comes with, but I expect that they are just intended to be hammered into the ground. I’d certainly try that before even thinking about concrete.

I don't see this (from the original link) working without the legs being fixed down in some way...

I wouldn't want my grandkids playing on that without it being well secured.
If you read the longer review, he says that he dug out the holes and concreted the anchors and frame in before a final tighten up when the concrete had set, as per instructions.
It seems like the anchors supplied are designed to be concreted in, although it's possible that ground screws could be used. It depends on the ground conditions and how long the screws are. Concreted in will always be stronger, but obviously doesn't allow for the swing to be moved so easily.

We had a similar but wider one than that, often with two kids playing on it at the same time. Just used the fixings supplied, and no concrete and never a problem.
Due to the substantial nature of the design with the wide A frame and the weight of the children, it hardly moved.

But security/stability will depend very much on how much concrete is used. A bucket full on each anchor isn't going to do much. A 500x500 pad, 100mm thick would be pretty solid and likely over the top. Personally, I'd go for ground screws as they would probably be cheaper than several bags of postcrete (quicker too - No waiting for concrete to set).

For the larger play equipment most companies seem to say 350mmx350mmx350mm hole size. Probably over the top, but nowadays they tend to be cautious. 
Postcrete is expensive compared to ordinary concrete, but does reach it's final set after 5 minutes compared to 24 hours, and hardens quicker, so the times not that much different. 
I'd use ordinary concrete and lock the kids up for a week.
