Hi All
Can anyone suggest the best way to fix the shed I am constructing to the concrete slab?
Thanks in anticipation.

Frame fixing is as good as anything.

If I get you right, surely the weight of the shed will be sufficient to stay in place on the slabs.

I've seen bigger things than a garden shed take off in a storm.

It's not just their taking off, it's what they crash into too.

Yeh possibly. However once his shed is stored it would need to be some storm.

If the concrete is good stuff, you could use frame fixers, like these
Drill a hole and screw it in. No marking, moving, drilling, plugging, moving back, lining up...

Just drill a hole, and screw it straight in.

Thanks for all your replies.
I should have explained more clearly I have laid a concrete slab 4 inch thick and built a frame to the dimensions of the slab. I want to attach the shed frame directly to the concrete slab. I intend to have the concrete slab as the shed floor(there will not be a wooden floor) as I want to store a ride on mower in the shed.
I have been recommended thunderbolts. Does anyone have experience of these. I think they seem fairly similar to frame fixings.
The dimensions of shed are 22 x 10 ft.

Don't forget to put some form of DPC between the timber and the concrete. I personally would also lay a row of bricks around the perimeter to site the shed onto. Its not essential, but it may help to prevent any potential water/rot problems later on.



I once had a two bay oak framed garage slid backwards in one severe storm. It move approx 600mm!! I had thought that my labourer had fixed it down, and he said that he thought that I had. It took a bloody lot of effort to get it back into position!
