Hello everyone, this is my first post in this forum. I have somewhat of a big project this weekend and need some advice. I am pouring a 15' X 30' patio slab 4" thick along the back of my house. Between the house and the slab I will be installing a fiber expansion joint since the house is still brand new and it still needs to settle correctly. But not only am I pouring a slab, I am also pouring a 2 level concrete step on the slab going to the house. my question is, do I also install fiber expansion joint between the step and the house or not? And if so, any recommendations on how to install since the fiber board is only 4" tall and obviously the steps are going to be 18" tall in total. Anything would be greatly appreciated. Thanks everyone and anyone!
