You can get someone to concrete it in either. I read an article about these in Superbike. Some come with a ball bearing to smash into the bolts thus rounding them off so they can’t be removed.
I’ve got an Oxford one, cant remember the model :ermm:. Bolts in about 3 inches into the ground, was fairly simple to drill the holes (fitted into a concrete slab) And then with the ball bearings to smash into the bolt heads, doesn’t look like its coming out anytime soon (fingers crossed)
When I bought my anchor (PJB Red Alert), I found it rather randomly on a site called Hygiene Supplies Direct. I’m not connected in any way,but did get it for 28 quid instead of 40 odd at other places.
That model comes with expansion bolts and ball bearings, you just need a massive drill bit to fit.
I have a Y anchor fitted into 60kgs of concrete. It would be better if I could have fitted this into a concreted area, but I only had a grass area to fit it in.
Think about the size of chain your going to use, the largest security chains now go up to 19.85mm. The larger Ground anchors cost around the same so if you fit a larger one you can “future proof” yourself should you want to upgrade later onand in the meantime you could allways fit two chains through them.
Once fitted give your insurance a prod as you might get some discount especially if the Ground anchor is sold secure or thatcham approved.
No link to the company, its the ground anchor that came with my almax - i bought it all as a package deal
Took me a while to drill a fat hole in the concrete floor of my garage but it makes me feel happier knowing that lifting the bike from my garage is going to be a lot of effort and noise. The fitting itself was easy, the drilling was a mission due to all the pebbles in the concrete. Had to break them up with a hammer and screwdriver
