Just about to start a decking project in my garden. I haven't built decking before, but I have spent some time planning my build out so I'm pretty much set. One question though. I've built good strong fences before and instead of concreting in the fence posts I have used metal spikes. I am wondering if something like this http://tinyurl.com/djf3l8 can be used to hold the posts that will support the raised decking instead of concreting in?
I guess my only concerns are that the spike once positioned and laden with weight from the decking and use of the decking, the spike could possibly be pushed deeper in to the earth and consequently allow areas of the decking to droop, if you know what I mean. Is this a valid concern or not?
Would be interested to learn if others have used the spikes for raised decking.
