Bolted Ground Anchors

[-Matt-]

Anyone had experience using these. I've only ever used concreted in ones in the past but won't be able to here, so its a bolt down one or nothing

It uses expanding bolts with bearing to prevent drilling to attach to the ground, but it seems like it might be quite easily to rip up with a crowbar or something perhaps

What I'm doing when I get the house I'm looking at with a garage is getting 5 or 6 D locks and sinking 3 of them close together to make 1 big ring concreted in. Then do a 2nd on the other side 2 ground anchors.

Those ones, I'd expect a drill to bust the bolts.

Landlord won't allowing any digging of holes or concreting

Will be ironic if this thing gets ripped up and damages the floor

The trouble with all this security, ground bolts etc is the thieves will likely damage your bike trying to get then unlocked, bikes dropped, steering columns damaged, I'd personally prefer it if they just nick it and then never see it again.

I know you will have the hassle of insurance etc etc, but also don't want the hassle of having to fix my bike.

I know they can deter some thieves just by looking, so that may be worth a little.

Yeah it is a bit of the gamble either way unfortunantely. If it was a cheaper bike i'd leave it be, its just the amount a claim for this [which i would have to claim on] will rocket up my insurance for the next few years will be quite severe I think. So i'd rather a slightly damaged, hopefully useable bike, than no bike/claims at the moment.

If I was living in the USA i'd just rig up some shotguns to the door but sadly I don't

i had a bolt down anchor a few years back used some massive rawl bolts / anchors with snap off nuts on the end (like below) the hex ends snap off at a set torque leaving just the dome'd end on so they cant be undone - seemed secure enough, and was an utter cnut to take out when i moved house so i think it would have stood up well if anyone tried to get it out

How did you manage to remove it out of interest Landlords happy for a small bolt in one to be left for future tenants/owners luckily, so I should save myself some trouble there. Just doesn't want any digging or concreteing done in case it cracks the floor/ garage wall its being placed alongside

[P.]

For us that only have TPO insurance because anything else is a royal rip off and bound by billions of rules tighter than a nuns fufu, I'd rather they didn't nick it in the first place.

Landlord should be worried about the fact it might get dug out when they realise the bolts are stuck firm rather than being a fairly large sunken piece of hardened metal that won't get pulled up, ever

Into solid concrete with four, M8 rowl bolts? Put it this way, If they came in a van and tried to pull your ground anchor up, you'd find the back axle of a van attached to it next morning.

I just got one of the bars off a fence panel from the local scrappy, bent a U shape in the middle of it and cut a couple of notches out of a slab and put it under there.

Mind you, I've probably used it twice in almost a year, and it would only need a gentle tug to remove that and the slab..... but I only intended it to be a visual deterrent anyway

I've got the smaller 2 bolt version in my garage. The bolts pull the anchor in towards the concrete as you tighten them, no way you can get a crow bar under them.

The quickest and easiest way to break one would be to use a grinder to cut through it. I don't think you could pull it away from the ground, it's totally solid.

If you are feeling paranoid, go for this one. It's sold secure rated for caravans, which is a higher level than bikes, and it's only a tenner more than the one you linked to

make sure you use a good 16mm chain with a ground anchor. They are effective as a visual deterrent, as well as being difficult to cut

Large heavy duty plant pot, fill with concrete/post ballast with U-lock or hoop of steel/whatever suitable thing you can find down the local scrappies poking out the top. Pretty flowers on top

The other thing you can do is drill the holes and then put some concrete resin in the hole and push the bolt into that, you will never get the thing undone again though unless you grind the top of the bolts off. With the resin you stand more chance of pulling the floor up than just getting the bolts up. It's quite expensive though but compared to the bike and insurance it's nothing, just pop into your local builders merchants they should have some.

My friend Aimee came and fitted my ground anchor (Civil engineer - Lovely girl).

Drilled a 20mm hole, about 200mm deep.

Filled it with some squirt in resin stuff (Two tubes, which come out of 1 nozzle)

Then pushed in this Hench threaded eyelet thing, screwed it around about 10 times, to fill all the threads in with resin.

Next morning, I am left with a 100mm dia, steel loop sticking up out of my garage floor, which aint coming back out easily.


Granted, an angle grinder would go through it eventually, so it can be 'removed'.

But in the event of theft, you'd get through the chains quicker than the anchor, so it's as tough as it needs to be.


My tool box is the most valuable thing in my garage (About £15k all in), so that's anchored down.
And then my angle grinder, is locked away INSIDE the tool box, for obvious reasons.

No problems mate, it's the same stuff binge is on about. Good luck with it, one piece of advice though if you use the resin wait until you have drilled all four holes and then use it, otherwise it will go off in the tube and you will be screwed.

Can't help but laugh at that

Short of using land-mines and firearms nothings safe it seems. I would like to think my bikes not desirable enough to attract that much effort.

Did he have an alarm anywhere on the shed out of interest - i'd imagine thats one of the few situation you really would benefit from having some warning whats going on Seems silly to goto that level of protection without some warning device to alert you whats going on, must of taken at least a bit of time to dismantle all that!
