Crack in breeze block outbuilding

[Tetrapanax]

This garage/shed was built about 15 years ago. The crack appeared shortly afterwards and as far as I can tell hasn't changed since.

It is just used for storage etvc.

I'm currently at the stage where I need to spend money to repair roof so want to know best way to handle this. Do you think it is ok to patch it somehow? What would be the best way to do this?

Something more subtle than dynamite. A big sledge hammer or an excavator would do it. Give it a decent funeral.

PS. That’s not a crack, it’s the poor or zero foundations subsiding.

Terrible build!!! As above, dynamite it...

I think a small sledge hammer would do the job on that one

I feel for you esp if you personally commissioned it and you've also got a roof job to do - I know that one! given the price of materials and depending on how much time you have on your hands, is it worth disassembling it (not necessarily with TNT etc) de-mortaring the blocks, make an appropriate base then rebuild it from the salvage stuff I wonder. Anyone know what the economics would be?

Its stood for 15 years so its solid enough, just a general point up required

This was my thinking but seems to be the minority view here! This was built on top of very old foundations, to replace a triple garage that was no longer structurally sound (from I would guess the 1950s). Is the consensus that this is not safe to keep using - any other opinions?

It’s totally knackered!

Well 1 metre of foundation has failed but totally knackered is a bit OTT

My money’s on “totally knackered” over “just a point up required” but each to their own…

The blockwork has been built with sand and the foundations are highly suspect. How long would you go on polishing a turd?

Another 15 years? , it appears to be strong enough sand to hold the blocks together except where tension forces come into play due to settlement

No it appears like it looks - rubbish. Even the masonry that is sheltered from the weather (directly below the roof) is looking poor. The paint is the only saving grace for some of that mortar.
