Concreteing in a Ground Anchor

[Brick_Top]

Easy guys,

I've just purchased an "AutoXtreme" ground anchor off eGay.

It has a box section, with a crosspin and a swivel head.

It's got to go in my front garden (mud/shingle).

Can anyone link me to a comprehensive guide on doing this? I don't watch ground force, and I've never done anything like this before.

I'm hoping it's a case of buying some ready mixed concrete, digging a fuck off hole, pouring the concrete into the hole and resting the ground anchor in it until it's set.

Cheers,

Con

That's exactly it.

Dig hole.

Buy readymix.

Mix with water.

Shovel into hole, add ground anchor to taste.

Make the hole narrow and deep rather than wide and shallow, it will be much harder to pull out. If your ground anchor is 4 inches square dig a 12-inch-square hole. Don't use too much water when you mix it you want it to be able to support itself like a giant elephants turd not slump down like gravy. Don't stuff bricks/rocks down the sides it will be much weaker.

if you are even more lazy you can get a lorry come up to your door with premix and just dig the hole and wheel barrow it infor you about £200 last time but then I was laying a gigantic house foundation.

You could also use postmix which is the stuff used to secure fence posts. The difference is you don't add any water. Simply pour the dry mixture into the hole, stick in your ground anchor and leave. The mix will draw all the moisture it needs direct from the surrounding soil and will dry rock hard.

I'd bang some steel rods into the round to give the concrete something to cling to, should make it stronger as well.

Or you could put cellotape round the anchor?

As mentioned before, don't go mental with the spade action. There are often utility supplies (water, gas, electricity, phone line sewerage etc) that run underground at the front of your property.

9 times out of 10 your fine, but if you take your time you'll spot anything untoward before it gets serious.

B&Q or Wickes sell the post-fix bags. I would buy 2 of these (£3-4 each) and use as instructed. You usually pour half a bag in, water, wait, add rest of bag, wait. All done in a couple of mins and will be hard overnight, but full strength usually takes a few days.

It will also help if you have a length of 2"x2" to tamper (whack!) the mixture to ensure it has settled all around the anchor properly.

I have concreted a couple of ground anchors in in the last couple of years.

1) don't dig an enormous hole, as you will need about 7 bags of stuff to fill it, and that is a lot of work.
2) have an old pole and some bricks to hand, then you can hold the anchor through the chain eye, and keep it in the exact perfect position while the concrete goes off.
3) If you find some old metal shelf brackets, scaffolding pole, or dexion shelving to bash deep into the ground radially deep down so your concrete binds them in, then your anchor will be impossible to lever out without a 10 ton crane.
4) have some half house bricks to hand and if you are running out of concrete mix, you can push some in to raise the level of your wet mix. Builders call this using plums!

I used bags of ballast and cement which I mixed with a shovel, about 4 to 1 ballast to cement. But fence post suff should be just as good. Although I would use more than one bag, probably 2 or 3.

I got various lengths of strong chain, locked them up with old padlocks I didn't require, dropped padlocked ends in a deep hole, and filled with concrete. Tapped a couple of nails into the wooden gate post, and rested the other ends of the chain there whilst the cement dried.

stinkwheel Well I just had my hands up a pigs fanny. Which makes your concerns pale into insignificance.

[muddycoffee]

I can assure you that the oxford terraforce ones are sold secure, and they are also on the discount list on ebike insurance.
I bought my second one from ebay for just £16

So I now have one installed at my own house as well as my girlfriend's house.

Remember to wrap a rag soaked in grease around the anchor.
That way whenever you move house it's just a deft flick of the wrist and hey presto you have your anchor for the new house.

And since you've already fitted one. It will be a piss case to put that in.


Warning:
Be carefull if you're moving to a flat though.
You will need planning permission.

why make it easier to get out?
that defies the whole point of a gound anchor.. you may aswell tie your bike up with string instead of chains

After 4 hours of solid drilling with an 850W 110V industrial drill I managed to drill ONE 90mm deep, 16mm wide hole into the poured concrete and stone floor of my Garage.

Here's the hole (and the bolt on the left), the pair of drills (my own 500 W and the big hire drill and the anchor (ready to go in).

It took far too long to drill as the floor seems to be made out of Basalt rather than concrete . Actually it was a poured concrete/crushed brick/sand mix and I ended up having to use one of the 16mm masonry bits as an impromptu chisel. Basicly I shoved it into the hole and smacked it as hard as possible with a steel mallet (thanks be to the kind neighbours ) until sparks flew to break up the REALLY tough stuff I seemed to hit at about 70mm down.

I got the thing in and set it into the hole using the extracted dust and a bit of water as a mortar mix. Ok, it's only in by one of the 4 bolts but it'll be impossible to drill another hole without a motorised chisel and a whopping big drill to tidy the hole up.

To summise, Don't drill into a solid floor when you have the option of pouring concrete instead and setting the anchor in whilst wet.

Did you have that 850 m/c set on Hammer?
It should have went through that like hot pish through packed snow.
Was it a borrowed m/c?
Maybe the percussion mechanism is gubbed.

But what a nice hole you got boy.
