How to fix cracked bricks?

[otnimus1]

Hi community, my question isn't particularly related to garage but it happens that I'm replacing garage door.

I will get my garage door replaced and I just noticed that there are some cracks on the brick where the door is attached to. I hope the installer will make the right judgement on what to do but I would like to get your opinion for my own education.

As shown in the photo, there are some cracks on the bricks as marked in red. I know the bracket will be replaced but I don't know if any of existing hole will be used. Regardless the bolt will be attached on new hole or existing hole, do I need to do something about the cracks? If so, what should I do?

Would it do any good/difference if I patch/fill the hole with Ramset UltraFix? Or is there any other products that is more suitable for this? Thank you.

Hi @otnimus1,

Thanks for the photos and we can see there are no structural issues but... I am still dumfounded by the amount of brickwork damage likely caused by  very aggressive masonry drilling. Good idea by @R4addZ to possibly use chem anchors.

Hopefully it will all work out OK.

Cheers

Hi @R4addZ can you please elaborate what those chemical anchors are? Just so I know when I discuss it with them. Thank you.

Hi @otnimus1 

Most physical anchors are inserted into the brickwork and work by expanding outwards as the bolt or screw is driven into it. Some work slightly differently in that the bolt is pulled outwards expanding a sheath. Both of these put an outwards pressure on the surrounding brick.

Chemical anchors are effectively a cartridge containing a structurally rated glue and the anchor is driven into the cartridge breaking it and releasing the glue to fix the bolt in place (some use an adhesive injected into which the bolt is positioned) This means the outward forces are not present on the surrounding brickwork, just the force of the load of the garage door which is an outward from the wall and downwards force. This shouldn't crack the bricks.

Hope this helps

Yeah me too. Unfortunately I can't tell since when the cracks were there. I didn't notice or regularly checked, until we need to replace the garage door.

Thanks @R4addZ So I was in the right direction by thinking of applying Ramset UltraFix.

@otnimus1  Not if you were thinking of using it to fix the brickwork. The current brickwork is compromised and as such should be fixed properly considering the load it will have to take. That said, be advised by your installer as at the end of the day, if he says it will be ok then he is accepting liability if it fails.
