Hi all,

I've got some cracks I'd like to fill/fix and wanted to hear from you guys on the best product I could use that would be most beneficial.

It hasn't gone through to the other side of the wall - but it would be nice to just stop it spreading further, but also every time I see it (albeit it's at the back of the house) I want to fix it!




Thank you!

IMO that needs checking, that looks like subsidence

We had same on old house. Houses were fine, but all garden walls and garages had issues due to lack of underpinning when built. (they heavily underpinned the houses but didn't for everything else)

Thanks :)

I think what probably happened is someone hit the wall at some point - but you're right I probably should check for subsistence as well.



The red bit is "private" but public land, there's some commercial properties that have allocated parking there (where the silver car is on the left of the red line), but one of the neighbours used to bring his 7.5T truck home from time to time and park it there, and I'm sure he must have whacked it at some point. I can't prove it though - and he's since moved out.

To the right of the red line is our property (well the back / side of the house). The garage is used for my gym and storing some garden equipment so ideally I'd like it not to fall down! :D
 
Ah, funnily I was going to question had someone potentially driven into it.

If its that then its probably fine, you could always tie it together anyway although did you mention double skinned?

Its going to be a bitch to fix and not stand out.

Light brown silicon would be easiest but it wont look pretty.

Top job would be to replace the cracked bricks (one at a time) and remortar the lot where its cracked.
Spending some time with some sand and colour to match the mortar as close as you can.

It's public facing (i,e, I don't see them) so I don't really care about the aesthetics really. It's not cavity wall but yes double skinned - the cracks don't appear on the inside of the garage.

Ideally I'd like to just reinforce it and stop water getting in / freezing and so on.

Mortar will be tricky as gap so narrow
Silicon is slightly reinforcing
Could be worth looking into some chemical resin, will be semi structural and will fill in the variable width cracks fairly well (as well as silicon) eg
(it says not for cracked concrete but thats for it being used to mount things on as opposed to primarily filling the crack)
