This material can be installed on aggregate or on concrete. The material used for these greens is called polypropylene,just another word for plastic. The fibers do not have memory built into them and can not stand up by themselves. To get these fibers to stand upright you have to add between 7-12 pounds of fine silica sand to keep them in position. As you can appreciate, this amount of sand will blow, wash or shift and sand filled greens do require some maintenance.

The following maintenance will be needed for deep sand filled polypropylene greens:

You will need to broom the green vigorously 2 –3 times a month to stop the infill sand from clogging up and causing the green to turn hard and bouncy.
If you live in a rainy, dry or windy area you will need to re-sand your green with an eighth of an inch of sand, 3-4 times a year.
This material needs a ‘wear in’ period as the fibers have been lying down and will, after installation, still have some ‘grain’ to it. You will need to roll your green with a heavy roller, often, to keep the fibers from ‘standing up and forming grain.
