Yes, landscape fabric is often used under artificial turf, but its primary purpose in this application is weed prevention. It is typically installed directly on top of the compacted soil subgrade, before the aggregate base layer for the turf is laid down.
Select a high-quality, permeable fabric that will not impede drainage, as water must be able to pass freely through the entire system. Always check the artificial turf manufacturer's specific installation guidelines, as some systems may recommend a different approach or no fabric at all.
