Hi I am working on a project right now that requires a wooden nailer to be anchored around the roof perimeter of a building, however, I cant find any literature or specs on depth of the bolt into a concrete slab. The only information that I can find deals with anchoring into concrete masonry units (CMU) which requires an 8 inch bolt depth spaced at 4 feet spacing, but the concrete slab is much stronger and I only have a 5 to 6 inch thick slab so 8 inches would not work for my particular application. If anyone has a tip or where I could go to find the information I need, it would be greatly appreciated.
