Hey guys, I have an aggregate patio that I want to build some wood patio steps for. I am thinking of using two step stringers (the 24inx7.5in variety at HD) and starting about 4 inches below the patio (ie landing NOT flush with the patio). Is drilling a 2x4 baseboard into aggregate is similar to doing so in concrete? What type of screws or anchors should I use? What are your thoughts overall? Thanks.
The aggregate is about 12in tall in this picture. As you can see, there has been some erosion away from the patio.
