Do I just use sand? The middle part of my yard sinks in a bit and water collects there especially after we get a bit of rain, it doesn’t help that the kids like to use a slip n slide during the summer but is there anything I can do to level it out? I feel like sand might help but that’s a big divot. Any advise? Originally by u/rickyrick0515 on Reddit: https://tinyurl.com/29edcg2d
