Fixing to rocky ground

49801

Hi folks,
I must knock up a log storage shed.
Similar to but will be free standing (not against other building) and little bigger.

Thing is how to make sure it's secure to ground as it gets windy here.
The ground is fierce rocky and would have been jackhammered originally and only a thin layer of blinding there now.
Thought of concrete footing ain't appealing with how rocky it is.

My thinking is to use an L bracket, drill ground and fasten with a concrete bolt like https://www.screwfix.ie/p/easyfix-yellow-zinc-plated-carbon-steel-concrete-bolts-m10-x-120mm-10-pack/8215p

Is there a better plan or solution? Also thought of hammer in or chemical options

Not sure about the rest, but I can tell you this won't work.

Those things only work with the right sized hole with the right material. They really are designed for concrete and even with softer bricks you can easily blow out the hole without that much tightening. It's got no chance on in ground, no matter how compact.

Won't the weight of the firewood hold it down?

Ok not those so.

Weight of firewood will vary... so not confident in that alone.

Try suitable hilti anchors with injectable chemical

Design it with gaps for for wind to get through, like hit and miss fencing, to reduce wind load.

Wood doesn't need to be completely dry to season properly - the drying is from the inside out. Obvs if there is surface wetness it's harder to get lit, but I usually keep a stock indoors for immediate use.

Make a weighted base, and attach the shed to it.
Make it so base heavy it cant move.
