Base for log cabin

[bunchofkeys]

Has anyone built their cabin upon the ProBase tiles?

I'm looking to do this when it gets a bit warmer, and these seem like an ideal solution; when filled with pea shingle.

There's no way I can pour a new concrete slab - no access to the garden, other than via the house, and so just too painful.

Have just got a quote for groundscrews from Stop Digging - which look like a relatively cost-effective (and reusable/environmentally friendly) option. They will install and laser-level, for £60 per screw.

Anyone got any experience with these?

Fair enough. Hope it all works out.

I'm sat in my office / shed set on these now. Been up for 18 months and I'm happy I made the right decision. I went for 20 to sit a 14ft x 11ft shed on. Could have got away with 16 though. The guys who built the shed for me really liked the screws and said they actually preferred it to a slab.

They had to do a little shimming as the U shape of the top of the screws obviously have to face the same way so potentially you will have some a 1/4 to 1/2 turn out of true. It wasn't really an issue though.

One guy put my 20 in in half a day for £800 - £40 a screw. I'm near Clacket Lane on the M25.

Awesome, that's really great to hear. Suspect I'm paying a central London premium, but they said 14 would be enough for me. Given I've just laid 2m deep foundations (ruddy neighbour's trees) for my rear extension/side return, I'm loathe to add more concrete to the garden.

Is the celotex exposed from underneath? If so,what is there to stop vermin eating into it and nesting underneath?

Good question - what do other people do? I was concerned about having the insulation open to the air (even though it's foil on both sides, and then solid foam).

Yup, I did exactly this four years ago and had no problems whatsoever. Office is in daily use and it works perfectly. Laying those was far easier than faffing around with laying concrete.

I've used these for my Tuin Cabin

I'm pretty sure its not an issue. I've seen that type of insulation stored outside and nothing bad happens to it.

I saw these, and thought they looked good (and also half the price of the Stop Digging screws). But I did worry about installing them on a London clay soil - I'm not sure they'll go deep enough into the ground for my purposes.

My cabin is a raised up one,it's raised by about 40cm. I used deeper floor joists ,then fixed battens at the bottom of each joist and laid cheap ply board in each gap before insulating.
