Greenhouse base??
« on: February 18, 2007, 10:18 »
Got a couple of greenhouses given to me, not in very good condition, but was wondering what sort of base to use?  Was just gonna maybe put some paving slabs down then put them on that but any ideas for keeping them fastened down & secure??

                      Cheers.

I've seen a lot of greenhouses on paving slab bases where the slabs aren't laid properly. The result is that the slabs settle, the house goes out of true and then glass starts to get loose. Come a strong wind and the greenhouse is in trouble.

So, unless you can really get the slabs solid, I'd invest in some wood. Treated fence posts seem pretty adequate as long as you can get them fixed firmly. I've seen a very firm base where the posts were fixed to vertically sunk 2 foot posts so they couldn't sink etc.

It's worth spending the time and effort on the base as that is what will determine how well the house stands for the future.

another good base is 4 railway sleepers cut to the shape of the base, do this and it will give you extra head room aswel,expensive though if you buy them.

Could you elaborate a bit more John on the treated fence post idea, I'm not quite with you?  Do you mean laying the fence posts on the ground then the paving on top of that??

Hallo infowarrier - I made a wooden frame with 3by4 treated timber sized to fit the greenhouse base.  Wooden frame is anchored to the ground at the inside of each corner with metposts which each have a stumpy section of fencepost to which the frame has been screwed or bolted.  the greenhouse base has been screwed to the wooden frame which is at ground level.  Care required to get frame exactly level which involves a bit of fiddling about, but worth it 'cause both my greenhouses have been up a few years now and stood through all the recent tropical storms without damage.

I was supposed to be taking a pic for noshed but haven't quite managed it yet.  

You could then use the paving slabs inside the greenouse to make a path?

I think milkman has explained it better than I could.

Thanks

We've a base to lay....OK OH has base to lay for proposed greenhouse.  I have dug out the area (yes me not OH) and we plan to put down aggregate ie 40 to dust, sand and then slabs on top.

Will this be ok to fix a greenhouse to?

I don't want to go down the concrete raft route.

I'm using the Milkman method - slightly delayed by viruses and work but there may be pictures this weekend.

For my first greenhouse, I tamped the ground down well, levelled it and laid breezeblocks.   Finally, siliconed the frame to blocks.  No problems for the past year.  Had the blocks for free so cost me £1 for silicone - no maintenance necessary and rot proof!

Did you drill holes in the metpost socket to take the screws or bolts ?

Hi miker, the metpost will have holes already in them for nails/screws. :D

Thank you legendaryone . I still don't understand how if you use metposts and attach a wooden frame to very short posts in the metposts how the frame is at ground level ?

The frame wouldn't have to be fixed to the posts at ground level it could be fixed 6 inches higher for example, so the frame is resting on the ground but instead of fixing it to the post at ground level you just do it 6 inches higher. I hope i have explained it ok  :)
