Hello,
I am moving into a new house soon with a large garden soon and will have a log cabin/garage put into the garden. I am planning to buy the cabin/garage from www.tuin.co.uk and will be having a (level) concrete base installed to accommodate it. Now Tuin doesn't supply a floor as standard as they advise that people in other countries spend a lot on their base and as such don't require wooden flooring. I will be using it as a gym with a weight rack and if I can get one big enough also to include a full size pool table I have. However I am not sure if I need a floor or not, I will be covering the floor in gym mats or similar but am not sure how this will work in regards to waterproofing? I understand the base should have a damp proof membrane installed but does anyone a cabin laying straight onto a concrete base?

One local company stated that they would use silicone around the outside of the cabin to make it waterproof without a floor but they didn't have great reviews (not necessarily because of the floors but other issues) so I would be interested if anyone has any actual experience with this? The floors available are 18/27mm so i'm not sure how these would cope with 150kg of weights on a rack? All the cabins by Tuin are provided with foundation beams if that makes any difference.

Any help appreciated.

Cheers.
 
Just remember that you weigh (very roughly) about 100 kg, so if a floor can cope with two of you then you'll be fine.
 
I installed a TUIN cabin earlier this year. I Bought their floor, it comes with I guess around 35mmx35mm bearers. They looked treated so I am sure they would work as a floor. Ours is also a gym.

Are you getting a full height or restricted height cabin? Ours is restricted and I am only just able to use the treadmill. If your buying restricted be careful on installing expecially if you use the special beam underneath that angles the water away!

My cabin is on a timber frame. Its made using 1.75"x10" carcass. Then its got a lot of extra beams crossing and noggin in effect. Under that is a DPM.
On top of the frame (inside cabin only) is a layer of OSB. Then I put the supplied bearers on top, filled the gaps with 35mm or so polystyrene, then their floorboards over the top, 27mm version

Its pretty darn solid as each stage is screwed down to the one below. There is a tiny amount of flex if you jump up and down, when running etc
 
I've got a cabin going directly to the concrete base. The base is 10mm shorter on all sides so rainfall doesn't hit the base.

The concrete base is epoxy finished with carpet tiles on top on half.
 
Interesting thread this. As I'm going to buy the Aistle 5 by 3m Tuin Log Cabin early next year and install on a concrete base. It will be a home office/part shed.
I was going to buy the 27mm flooring also. So I will watch this thread with vested interest.
 
Well I had some fun with the cabin yesterday. Had a call to say the roof was coming off!
When I got more detail, part of the felt had ripped off. Typical woman over drama

I drove home and found that about half of a strip was indeed off. It was fairly badly damaged as well, now also rain was due, plus it was V windy

So I checked out the felt and figured as a temp i could nail it back on. Luckily when I first put up the cabin we had afew leaks, managing to seep between the felt nails so I had bought a tub of a resin roof sealent.

I managed to nail down the felt, leaving a 1-2mm gap in places. A thick coat of that sealent and it seems to be watertight. Not sure how heavy the rain was last night but it looks to be holding.

I was planning to add a false roof with insulation next year anyway. Will just have to happen now as I wouldnt want to trust that felt in the future. Now I look at it, i probably didnt nail down the back well enough (where it failed) the othr 3 sides the felt is also held in place by the roof boards, but down the back where the water is supposed to run off there is a gap left so it wont rot the wood. Oh well you live and learn ;)
