Thanks to Covid-19, I started to build my own Home Gym. In my garage, I have concrete flooring so I built a lifting platform on top of that to prevent any damage. I have 2 layers of 5/8" OSB with another layer of rubber flooring that is glued on top. I am trying to bolt down my Squat Rack with concrete anchors, but when I get towards the end of fastening the anchors, it begins to lift up the wood below. I drilled thru through the lifting platform and into the concrete. What is causing this issue? Do I need to drill further into the concrete or keep fastening it? via /r/DIY https://ift.tt/2WQXelQ
