We utilize concrete donuts on all heads installed adjacent to driveways and streets to protect them from vehicle traffic. They help stabilize the heads and gives them a chance against cars. The donuts are available locally here in the Houston area from wholesale irrigation suppliers and come in different sizes for different type heads. I've seen plastic "protectors" sold at the big box stores, but they are essentially worthless and provide no protection.

All Wet,

Thanks for your response; really do appreciate it. I can definitely see their use along driveways. I have a long one that has subtle curves in it and I have seen time and time again where friends, Fed-Ex, UPS, et al, have had a tough time backing up ... many times going over the edges onto the lawn areas ... not bad, but I cringe as I think about the sprinklers. To be fair to my builder, he did ask us "Are you sure you want a driveway with subtle curves?". Well, my wife and I too like the look, but I now know what the builder was probably thinking. LOL! Surprising though, none of those sprinklers got mashed. Just lucky I guess!

I haven't been able to find anything at our local big box stores, meaning HD and/or Lowes. I called a few local plumbing/piping supply places, i.e., Apex (now owned by HD), but that turned out to be a "no-go" as well. LOL! While I described the item in reasonable detail (so I think), none of them carried them ... now I can "talk the talk" ... "concrete donuts" so I can be more specific in my searches and/or discussions with folks on the phone.

Again, thanks so very much.

Orbitonline.com has two. Plastic. Called Sprinkler Guard Donut and Sprinkler Spray Guard.
Another unique one is at Sprinklerbuddy.com

Generally, they are called spray guards or donuts. You can find some on Amazon and possibly eBay.
