Give me some of the, uh, uh, examples of why these things develop.

Yeah, there's, there's certainly many, um, and I think it's important for building owners to be aware that, you know, there are many different causes which relate to multiple different repair methods.

So understanding why the crack is occurring is important in repairing it so that you're not just repointing every single year, throwing money down the drain.

Um, one of the reasons, or one of the causes of cracks, um, as an example, could be related to building settlement, um, which is one of those where just repointing [laughs] is, is never going to, to solve the issue.

Particularly in our area, we have a lot of, um, expansive clays, marine clays, fatty clays, and, um, foundations sitting on those clays are subject to, to movement.

Um, so those cracks may actually open and close as the building moves with the expansion of the soil.

Similarly, um, if the building's founded on poorly compacted soils, you may have just continual differential settlement as the building moves down and those cracks continue to, to grow wider and wider.

But the real question is when should you be concerned about these cracks?
