fixing a greenhouse to its base

(1/2) > >>

baz621:
Hi everyone, i was given a 8 x 6 greenhouse which is not glazed by a very nice neighbour at the allotment. I made a base of concrete footing and solid concrete blocks levelled and laid on their side on top of the footings. We moved the greenhouse onto said base, it was built up and ready to be fixed to the base and glazed. I didn't have time to fix it to the base, and in the mean time a storm has done some damage to it, but its repairable. I was going to fix treated baton to the concrete blocks and screw the greenhouse to the baton. I know the dimensions are 1928mm x 2568mm of the greenhouse, but do i need to allow any extra room to the dimensions or should the outer dimensions of the baton the same as the greenhouse (1928 x 2568) as the greenhouse will sit on it?
Does that make sense to anyone!!!!! :happy7:
Thank you for your help and advice

Personally I would forget the timber and screw the base directly onto the concrete base.

What will happen over time is as water run off impregnates the timber even if the timber is treated it will eventually rot, whereas the concrete blocks won't.

If levelling up is a bit of a problem have a few washers at the ready to act as shims.

An alternative to this to to lay a thin layer of mortar on the blocks sit the greenhouse on it then screw the base down before the mortar sets.

If you go the mortar route, don't do it if Frost is forecast.

saddad:
Check the bottom rail, most aluminium ones have a lip that needs to overlap the base, timber or concrete, so check before you make the wooden base... if the timber is treated you should get upto a decade from it and it's more forgiving if you get the measurements slightly wrong! (Easier to alter!)

ACE:
Don't use cheap  screws they will rust out in no time. Have you thought about using imitation wood, extruded timber I think they call it. I have a garden bench made out of it, no maintenance needed at all and no rot even after about 15 years

ancellsfarmer:
I would:
Ensure you have sufficient headroom; its easy to build up more internal height at this stage.
Drill the aluminium to make fixings optimum, ie miss joints.
Leave all screws loose (hand tight!) until glass is in; squareness is negotiable!
Agree with shims and positioning on outer edges. Silicone seal twixt base and frame will discourage insects (ants/woodlice etc) and hold from creep.
Consider the fall to the ends where you can place butt(s)
Dont climb over glass! Use opening vent as access to ridge.
Keep a few spare sheets of glass for emergengies.
Good luck.
