Hi All,
Any know why this Foam strip is used between the joint of two wall?

I can see this in multiple places where there is a corner joint. There is no Mortar/Cement used to connect them. If we remove the foam, we can see thru the hole. Will it be close later or left like that?

Thanks

I would say check your engineering drawing. If that's not an expansion join I expect to mortar in there.

It's Abel Flex , used in between structures so if the concrete expands doesn't affect the other structure. I haven't seen it being used in between bricks thou.

here is more about it.

Its actually very common for brickwork expansion joint. They just seal it with color matching sealant so most times you don't see it.

The Engineering plan doesn't have anything mentioned about Bricklayer. The plan has details about Slab, Structural Steel and Site BAS/BOS Plan.

I hope its the same thing you mentioned. I already have questions to ask list. Will ask my SA next time I meet him.

Thanks

Your engineering plan would mention where the expansion joints will be.

Anyway, 2 possibilities, it will either be covered up with mortar (for corners) or sealant. (sealant is definite for expansion joint).

Definitely they won't leave it like that.

May be that's why I haven't seen them in between the bricks.

That's all OK, in terms of contemporary Australian building practice. It's an articulation joint at a wall offset where there is no lateral restraint requirement in the design.

You don't want to think too much about why it is OK in terms of building practice. It's all to do with lighter-weight footings and foundations and a desire that movement in those elements not cause significant cracks in a building's visible masonry.

There may be a lot more happening around that joint that you just won't see as a customer, things like flexible brick ties and slip-joint devices. Enjoy.

It will be silaflexed if say

They will use mastik or ableflex to fill the joint. Its an expansion joint so needs to be flexible and will look neat
