Bolting post support into brick pier

[ColBatGuano]

I've got a sandstone paver covered brick pier that I need to bolt a T-blade onto (for a verandah post).

Are dynabolts ok, or should I use something like Chemset to glue bolts in?

Are you anchoring to the paver or the brick pier under?

If your worried that the brick pier might crack due to the expanding anchor (Dynabolt) then use the chemset. factors that would affect splitting the brick would be its dimenions of the pier and the size of the bolt- i assume u would use a 8mm diameter bolt. a larger bolt means more potential to crack the brick when tightening - or you could still use it, just do not tighten it excessively.

the technical manuals might help you... Ramset Australia (http://www.ramset.com.au/Product/Detail/82/DynaBolt-Plus-Sleeve-Anchors)

I generally would go for the chemset when dealing with existing structures because it is a safer bet. :U

It's a brick pier with a sandstone veneer. The brick will be holding the piece down - and 8mm sounds like it would be the way to go (if chemset isn't too expensive!). Off to bunnings to check on prices!

or use ankascrews which used to plan work well, but place less strain on the masonry - unlike expanding dynabolts which can be over-expanded accidentally so cracking the masonry.

Ended up using Chemset - dead easy to use and it came up a treat.
You feel like you can't go wrong compared to dynabolts.

Thanks for the help and advice!
