I used this in a parking lot at a local farmers market to block people from hitting an AC unit. I think it will work fine for a while but will most likely get damaged eventually. They are thinner than expected and completely sealed so you can't fill with concrete unless you cut the top off. Customer was on a budget and they are happy with it because they had nothing there before. If you want to stop drunk drivers from running into your corner store at 2am I would go with something stronger. Also, for install I buried these about a foot down in a hole with about 100lbs on concrete.
