Attaching metal post to brick wall

Attaching metal post to brick wall



there is 7 x 3.5 m pergola - one side attached to the brick wall and the other side resting on 2 poles.


Tradesman has finished the job but the metal post that is attached to the brick wall has not been fixed properly. 7m length sitting on 3 dyna bolts, and 3 holes on metal post as seen on the pic (without any screw / bolt). I feel concerned that pegola may not be able to withstand rain / storm. 


Can you pls guide - what size screw / bolt should I use to complete this unfinished job?


Many thanks,

Re: attaching metal post to brick wall

Hi @diy_ujjaval,


It would be helpful for our members if you could let us know the thickness of the beam. You'll need to use Dynabolts, and I would believe something like the Ramset 10 x 100mm DynaBolt Plus Hex Nut Bolt would be sufficient. If the current holes are less than 10mm in diameter, you'll need to enlarge them or select a thinner Dynabolt.


Please let me know if you need further information or had questions.
