I just built a weight bench I keep in the driveway of a house I rent. I can only put the bench in this spot at the end of it as seen here: https://ift.tt/2TYQAYZ. As you can see, the ground Is very uneven, what can I add/do to make the bench level without pouring concrete since i'm only renting? via /r/DIY https://ift.tt/33lAwn6
