I'm reworking some of the pool plumbing in the backyard and I've noticed that it's buried in a fairly shallow ditch, averaging 6-8 inches deep.

Since I'm doing the work myself, I was thinking I might cover up the plumbing with a hard surface.....maybe tile? or bricks? .....something that wouldn't rust, or deteriorate.

Any suggestions on what to use? I want to roll sod out onto this area, and I just know that someone is going to decide it's a beautiful place to jam an umbrellla pole or volleyball fence into the ground, at some point in the future.

Thanks
