• Bleurgh... Was there last night dropping off some stuff. It's not concrete out the back, it's square paving slabs. I'm assuming if I stick an SDS drill into one of those it'll shatter it immediately.

    Any other options to secure it to a paving slab??

  • You can drill slabs with a core bit on non hammer mode, but I wouldn’t bother as THEY could just break the slab to “borrow” the rack.
    You could remove a slab dig down and replace it with a concrete pad and then bolt to that? If you push some rebar into the ground around the hole and down to spread the load you won’t need to dig down too deep.

  • If you put rebar into the ground, wouldn't it be an entry point for rust? Or did you mean put rebar into the hole, but have it fully encased by the concrete?
