Spiked post socket?

I've just read up on those, will I be able to drive that into tarmac do you think?

Probably. Just hope there aren't any large hard rocks underneath.

Thank you so much :) I'll try it!

I would have thought that the flanged type of socket would have been better - such as

In concrete yes, but I doubt that tarmac would hold together for long. Obviously it depends on the thickness of the tarmac and the nature of whatever is underneath it.

I suppose if depends on the quality of the anchorage - my experience is that tarmac comes up quite easily as soon as anything starts levering it so if it were me I would look for a solid concrete anchor beneath the tarmac.

How about starting off by trying to drill a deep hole with a masonry bit directly beneath the where the post will stand? That will tell you what sort of substrate you've got beneath the drive - solid concrete? soft earth? If it's very solid, then you could probably fit a flanged socket, using long bolts and a builder's resin I'd suggest. If it's pretty soft, then you could drill a few more holes immediately next to the original hole (still within the footprint of the post) and this will break up the tarmac surface sufficently to bash a spiked socket through.

Try drilling in the intended location of the post with a long masonary drill first.
