Hi I'm going to install rails on the front porch. It's 4" concrete slab and I'm not sure what's underneath the slab.
The post for the rail requires 3/8" concrete screws to secure the bottom plate. What screw length would work for this? Is 3" too deep for 4" concrete slab and eventually it will crack the concrete?
