How to mount post supports (stirrups) on a concrete slab?

[hassall147]

Hello. I'm building a carport. I need to mount galvanised post supports (stirrups) on a brittle concrete slab. Normal procedure would be to use Dynabolts, but I'm worried they will but additional unnecessary stress through the slab and perhaps crack it. Can I instead use an adhesive to anchor bolts in place (sometimes referred to as a 'chemical anchor' ) ? If yes, what sort of adhesive would be recommended ? Many thanks.

Thanks Mitchell!

I really did get lucky that day as I seriously doubt my hand-mixed concrete is/was "32Mpa".

One advantage with the bolts I find is despite 12 years on - they can still be easily removed and re-inserted.

Cheers!
