Base Preparation
Preparing a base for artificial grass starts with removing 3-4 inches of dirt or sod, grading at 2% for drainage and laying wire mesh against gophers. Edging, 2.5-3 inches of compacted base rock, 1-1.5 inches of 3/4-inch decomposed granite and an optional weed barrier follow.
Prepare Your Artificial Grass Base
- Begin by removing 3-4 inches of existing dirt and/or sod. Clear off any obstructions from the work area such as sprinklers by either capping or moving them. Make sure that the base surface is clear and level, with a grade of 2% for drainage.
- Install wire mesh on top of your soil and before you add the base rock. This will ensure that your garden has a barrier so that gophers can’t get in and start digging up.
- It’s recommended to use bender board or metal edging so that you can frame and protect your turf from soil and loose debris.
- Lay 2 ½ -3 inches of base rock.
- Compact base rock to 90% by hosing down. Use the vibrating plate compactor to remove any remaining debris, creating a smooth surface.
- Lay 1-1 ½ inches of ¾” decomposed granite.
- Hose down and compact this second base layer to 90% as well.
- Install a weed barrier over the road base or decomposed granite. This weed fabric is recommended if weeds have been a recurring problem in the soil underneath the artificial grass.
