Fixing greenhouse to slabs

cubegame

Good morning.

We finished putting up and glazing a new greenhouse yesterday. It's in a sheltered spot but I still want to fix the base down to the slabs on which it is on.

Any ideas which fixings I should use? I am concerned about the potential for an expanding fixing cracking the slabs.

I drilled the bottom bars on mine and got some big screws / bolts to screw into the concrete.
Unfortunately i didn't do it until after we'd had a windy day and woke up one morning to find it the other side of the garden.

I think that greenhouse was mine ...

Just like other jobs in this house the greenhouse was not put
together perfectly and therefore is not square. It sits on a concrete base and I don't believe it is fixed to it (could be wrong though). Maybe it is stuck to the concrete somehow? It's in a good spot for the sun BUT, when it rains it is full of water - like today.

I am having a rant as today is a bad day in this house and I always think that if a job is worth doing etc... but they never are. Sorry to butt in.

Drill the middle of a slab, big washer or spreader plate on the underneath and bolt running up through. Hole in the greenhouse frame, drop it over the bolt, washer, nylock nut.

Really needs to be done before you put the lot together, doing it into slabs afterwards could be an issue, as you can't get a washer and the head of a bolt underneath.
