Want to put some kind of protective material under a kid's swing set.
I remember reading about, a long time ago, a rubberized material, sold
as pellets or chunks,that is suitable for outdoor use.
Probably many different types and kinds available.
Can't remember any of the details, though.
Might someone please point me in the right direction
for this ?
What are they called, who mfg's., etc. ?
And, any to stay away from ?
Any thoughts on what to put underneath for protection would be most
