What is artificial grass underlayment?
Artificial grass underlayment is the layer between your artificial grass and the ground. Yup, it’s really that simple. Underlayment is usually made out of rubber, cork, rubber cork, felt or foam.

What underlayment is Best for Carpet?
For artificial grass carpet, you will almost always use a foam or rubber carpet pad. These pads come in many different thickness options ranging in properties and pricing. Thicker pads will (typically) make your floor softer and more comfortable to walk on. We suggest using a foam carpet pad for broadloom carpet, and rubber for carpet tiles.
Make sure to pay attention to the properties of the carpet pad you’ re looking at, not just the price and thickness. While you can find some thicker options at lower price points, they make not do all the things you want them to do (like absorb sound), or at least they might not do them very well.
Make sure to check out those specs! The Carpet Cushion Council (yes, that’s a thing) recommends a minimum of 1/4 of padding under residential carpet, though most people buy a 1/2 artificial grass underlayment.

How to Install artificial grass underlayment
Installing artificial grass underlayment is a lot easier than most people think. In fact, I can outline the process in a few simple steps:
Start by rolling out the artificial grass underlayment one row at a time, perpendicular to the direction the flooring will be laid.
Tape or adhere rows at the connecting seams. Some artificial grass underlayments come with an adhesive strip.
Don’t overlap artificial grass underlayment unless the manufacturer recommends it.
That’s it! With a few tools and a little labor, your artificial grass underlayment is ready to go. Of course, it's always good to check with the manufacturer to see if your product has more specific directions.
