I have a brand new home with a 14X30 attached and covered Patio. I want to add 30 inches on one end of the Patio from the house to the end of the patio. (This is where I intend to keep my grill and smoker.)
So, my new concrete will be 30inches by 14 feet. Do I need an expansion joint between 14 foot of existing patio and between the 30 inches and the house slab? And if so, what kind and size joint?
I intend to do this using approximately 20 bags of sakrete. (I plan to have extra, on hand.)
