Asphalt bolts to secure shed to driveway

[sjws1888]

Hi.

I'm thinking about buying a steel bike shed which I would be putting on the driveway which is tarmac.
I've just been looking at how I would bolt it down since I know that concrete fixings won't work on tarmac.
I've found these asphalt bolts at toolstation (I'm sure other places do them too):

Just wondering if anyone has used these or anything similar of for this type of job and if so are they any good?

Cheers

Are you expecting them to be secure or just to stop it blowing away in the wind? Really you need some chunks of concrete under the tarmac and cast some studs into them, then tarmac over with the studs protruding. Or just bolt into the concrete after you've relayed your tarmac over them.

Just make the shed a dead weight.
If there's enough room inside, bolt a concrete fence spur to each corner.
Or you could do something externally, less pretty.
Saves mucking about with your drive.

Thanks both for your replies. So I take it from freddiemercurystwin's comment that those asphalt bolts would be easy to pull out of the ground? i.e. someone could pull the shed upwards and the bolts would come away from the ground? I don't really want to damage the tarmac by digging it up, and I dont think the shed will work if I bolt concrete spurs into the corner, but thanks Deluks for the idea.

I'm wondering if it would work if I just lay some concrete pavers down to create a base and then sit the shed on there and bolt it down to the concrete pavers. Would that work?
