Ground Anchor Recommendation

[chickenstrip]

I'm having a shed installed for the bikes soon. Size is 10' x 8', to hold both bikes but with room to work on one if the other is pushed outside (hopefully - I don't really have room for anything bigger). It will be on a concrete base, and I want to have ground anchors installed. I was thinking maybe something that won't protrude above floor level, just to make things a bit easier? Anything about that fits this description? Or if not, what ground anchor set-up can you recommend? Ta.

You're thinking of something like a Yanchor.

Retractable anchors exist.

I was just going to ask this

By concrete base do you mean the shed will be mounted on a concrete base but have a standard flimsy wooden floor? Or there will be no floor and just the concrete base?

Not sure how it would work if you have a wooden floor without cutting a hole in it?

This is what I was thinking, so I may not be able to go with a flush fit anchor after all. So, any other anchor recommendations that will do the job? Should I go for two anchors, or use one chain to secure both bikes (as the main security - will also use disc locks etc)? I see lots of anchors available, just wondered if anyone could suggest any particularly good ones, any general thoughts and ideas of the best way to go.[/quote]

there are other anchors, I only gave an example.

If you are setting the concrete yourself you could go crazy and bury some 68mm plastic gutter down pipe 150mm below the surface with two 45 degree bends to bring it up the the surface in a U type shape.

\ \__/ /
\____/

In the 150mm put some thick metal rebar rods, crisscrossed, bent so they extend further down into the concrete etc.
To get the anchor out you then have to pull out or cut through 6" (or more) of reinforced concrete.

Obviously check that the chain fits through the pipe before you concrete it, and that the chain's going to be long enough.
For drainage purposes you could (actually should) recreate the Y pipe, with a simple hole drilled in the bottom and a bit of down pipe gaffer taped in place (it won't go anywhere once the concrete around it sets).

Cheaper than and I'd guess as strong as most surface fit ground anchors.

I'd be very surprised if they go beyond 4" base + hardcore below. I wouldn't be surprised if it was less.
For a shed, I don't suppose they'll be putting in any DPM, with a timber floor above with ventilation between the concrete and the floor it won't be necessary, and it's just a shed. On the other hand a DPM sheet is what, £8?, and bringing it up to tie into the shed structure isn't that big a deal. Definitely overspec for a shed though (I always seem to go a bit over the top on simple structures).
My suggestion for the sunken anchor would need a deeper hole dug in that one spot, and if was me, taking that route, I would do that first. Dig the hole, bit of hardcore then some gravel at the bottom, then knock up a bit of form work around the top to get the levels right to where the shed base will ultimately be. Mix up in a 'barrow and create your sunken anchor.
They can do the rest of the shed base after, working to the level of the anchor.

It would probably be easier to get an above surface anchor and just create a concrete recess for it to sit in. Effectively dig the same hole as before, and make your formwork up to below the final shed base level. Then when it's gone off gaffa tape something the right thickness on top of your little block of concrete (polystyrene foam for example) and they then do the rest of the concrete base to the level of the top of your foam. Once it's all set, you pull the foam out (break it up if necessary) and voila, a recessed anchor, that you can cover over to have a flat surface if you want.


I can measure my almax and report back later in the week, but they are big feckers.

Edit: Pictures above, I won't bother measuring!

Go to your local metal merchant with the chain you want to use, find some thickwall box section your chain fits inside. Weld up a T or Y shape, weld some rod into the the base of the T/Y, concretre in. Estimated cost: £5 in metal from the scrap bin and a crate of your pet welder's favourite beers.

Surely you can screw bits of wood together.

Dug hole, concreted in a mooring ring..assembled shed.
Could've done with help putting the roof on but manageable.

If it comes with felt then specify they use the thickest available or double layer it.

Even if it's pressure treated timber get some nasty nasty stuff from wickes and slap it on.

I don't have the confidence to build a 10'x8' shed myself with a dodgy arm and shoulder. Yep, will be weatherproofing it - any suggestions as to the best stuff? It comes with a base coat, was thinking of having a mosey around B&Q for something suitable. I'll ask them about the roof felt (storm Des tore off some from the small shed that's currently in place).

How much is it costing you for the shed and the base? I'm looking at getting a 16' x 10' one (roughly £1k for a decent one) and sitting it on paving slabs, but I am considering putting a concrete base down if it's not too expensive.

I really wish I'd bought a flat / flush anchor than the toe stubbing bastard that I went with
