Those beams will be located exactly where your currently have your articulation break.

But from what I see, the extra cost will be cost for two extra edge beams along the patio perimeter (concrete and reo mostly).

Yes we have plain brick veneer with timber frame. I've discussed the dual slab idea with our builder and he estimates $10k plus engineering for the dual slab idea, does this sound accurate? I am concerned about movement of two relatively independent slabs although other alternatives such as paving may move as well. I never though it would be this hard Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Thanks for your help StructuralBIMGuy and alexp79, we really appreciate you guys taking the time to reply. Thanks for the insights, that makes perfect sense, and yeah, I will be leaning on the experience of the excavator operator entirely. 6 16325 Firstly the ableflex that has been installed needs (manufactures specification) a sealant cap over the top, preventing water draining down between the slab and the… 3 7871 If your patio is going to be 35 sqm then that's going to need Council Approval.
