Hi
I have an existing patio with balustrade round the perimeter attached to 900 mm square wooden posts.which appear bolted to breeze block base
The post is to be attached to a breeze block wall to extend the balustrade
The bolts have M12 written on them but I'm unsure if the M12 fixing used goes into a masonry plug or are concrete bolts which don't require a plug.
I have never attached to breeze block so unsure but wondered if these would do the trick.

Any advice would be appreciated
