Has anyone done this successfully? I’ve seen a few recommendations to use chemical resin like Vinylester, but wondering if there was a better way …

Yeh I’ve used them in my garage for lots of things. Trying to drill a nice clean hole isn’t easy but the anchors are solid once in.

@Gary_M did you just use regular expanding bolts?

Resin all the way. No expansion force so the block won’t crack

I’ve got a few anchors in my garage, just regular expanding metal ones. Hold fine, there not coming off in a hurry. IME you need the good metal expanders cos the holes end up being oversized, regular plugs not as secure.

Just put them in the right way round… 😳

Resin + 2

Fischer do them.

Yes just regular ones prezet. They work perfectly fine. What are you putting on the wall?

I want to put a wall anchor in to chain my vertically hung bike to. But it’s a new build house and the walls in the garage are thermolite blocks with a plasterboard skin.

If I went the resin route, would I drill the hole, fill with resin and then what do I use then?

I want to put a wall anchor in to chain my vertically hung bike to

I have almax wall anchors and 19mm almax chains hanging from mine and I could probably swing on it. It’s solid.

I had little success with the glass vial type anchors as there just didn’t seem to be enough resin in them to hold the fixing in place. I’ve got a cartridge thing at home to have another go when i get around to it.

I’m not sure that I’d bother putting a wall anchor onto a wall that can be cut with a handsaw

My Gun safe is fitted into Thermolite blocks with Resin and Stainless threaded rod.
Police seemed happy with that method of fixing.

Is your friend here!

I also found some Fischer fixings that had 4 large flanges off the body in a screw pattern (1 turn in 75mm). I had to drill out the center of the plug width, then hammer home and they were able to compress the thermalite block sufficiently to ‘screw’ themselves in. The police deemed that acceptable on my gun safe.

@timba To be honest I’m just trying to stop an opportunist scrote. If someone REALLY wants to steel something they will. I’m fairly sure they wouldn’t be able to cut through the wall with a handsaw. It’s also an internal garage so they’d probably make a fair amount of noise and wake the dog 😀

My thoughts were to use a more suitable adjacent surface, e.g. the floor. It probably wouldn’t be as neat (with a longer chain?) but more secure
Anything that works is fine in my book 🙂

Prezet, thermolite blocks are extremely easy to cut with handsaws.

Sorry guys, Builder here, I would put the anchor in the concrete floor you’d be able to pull it out of a thermolite block with a reasonable sized lever, and fairly quietly I would imagine.

Earlier this week I needed to trim a Thermalite block & didn’t have a saw. I used the corner of a metal scraper and easily scored 1/3 of the way through the block across its length in 10 min or so.
If you do go ahead, Fischer FIS-V resin, make sure you scabble our the inside of the hole & then brush out/suck the dust out with a hoover.
Pump hole at least 1/3 full of resin, withdrawing nozzle as you go then put anchor in using a slow twist motion. You should have some resin coming out of the hole. If there’s not enough you can remove the anchor then out more in if you do it immediately.

Does anyone else’s insurance stipulate d-locks? Doesn’t say what it has to be locked to though so I was thinking of just running some security chain between ground anchors and locking to that. Bikes stored vertically are wall mounted on a stud wall so there’s nothing to lock them too otherwise.

Thanks for the advice guys. Looks like using the concrete floor and a longer chain is the way to go then.

depends how far you want to go.

You could remove a thermite block or two from the wall (easy, they are soft)

insert big metal plate with anchor bolted to it.

bit of rebar and some shuttering

mix some concrete and fill the hole.

Then if they did lever the lot out of the wall, they would have bikes attached to a big heavy concrete block.

more likely they will just use your angle grinder to cut the chain…..

What a terrible idea for security. If I was pinching things, I’d just use a plasterboard saw and cut around the anchor and take that bit of block with me.

Yes it really is that easy.

My house is thermalite. To hang small things on the wall I knock nails in. It takes one knock with the hammer.

There’s no way I’d bother with wall anchors – far too soft. You have to remember that when you are testing things for load in your garage you are being careful, because you don’t to break it. Well, scrotes DO want to break it, and when you watch videos of stuff being nicked you realise how much force you can put into something you really want to destroy.

My bikes are stored vertically, I used a longer chain and an anchor in the floor. Took me most of two battery charges to drill the hole, rather than a few of taps with a hammer.
