Artificial grass installations, as the name suggests, replace natural sod or bare ground with a synthetic turf surface made from materials such as polyethylene or nylon. Artificial grass is becoming popular because it requires low maintenance, including no mowing, weeding, fertilizing, or regular watering.
Additionally, artificial grass can withstand heavy foot traffic, chemicals, and pets while staying green year-round, and it is not associated with allergies to natural grass pollen.
Have you been thinking about artificial grass installations but don’t know where to start? You are in the right place. In this artificial grass installation guide, we will outline the step-by-step process for installing artificial grass safely.
Step 1: Remove Existing Grass with Effective Pruning
The process of installing artificial grass begins with preparing the ground surface, including pruning and removing the existing grass. To remove the existing grass, use a shovel or sod cutter to dig down 2 to 3 inches, or up to 4 to 6 inches, depending on your base level of soil removal, to remove the grass, roots, and topsoil.
Effective pruning removes specific plant parts, such as branches, buds, and leaves, to free up space, control size, and benefit artificial grass installations. Locate and identify all irrigation or sprinkler lines and valve boxes to prevent underground water leaks. Apply a pre-emergent or broad-spectrum weed killer to the excavated soil to prevent future weed growth.
Step 2: Build and Compact the Aggregate Base
Once you have prepared the surface for artificial grass installation, the next step is to build and compact the aggregate base. Begin by laying a porous weed barrier fabric, overlapping it by at least 6 inches, and securing it with landscape staples. Then add a 2- to 3-inch layer of crushed stone aggregate, such as quarter-minus or decomposed granite.
Rake the aggregate to create a smooth surface with a slight 1% to 2% slope, about a 1-inch drop per 5 to 10 feet away from structures, for drainage. Finally, compact the base by lightly dampening the stone with water and compacting it firmly with a motorized plate compactor or tamper until solid.
Step 3: Roll Out and Fit the Turf
After creating an aggregate base, you can now roll out and install the turf at your site. Roll out the artificial turf and let it rest in the sun so the seams relax. Ensure all pieces face with the grain of the grass running in the same direction toward your primary viewing angle, such as when facing the house.
Cut the turf slightly larger than the space from the back side with a sharp utility knife or box cutter, then use a separate stretcher or turf grabber to pull the turf taut and eliminate air pockets or ripples. Additionally, anchor the perimeter with 5- to 6-inch galvanized nails or turf spikes spaced about 6 inches apart.
Step 4: Add Infill and Brush
This is the final step in your artificial grass installation. Spread the infill, such as silica sand or specialized infill, evenly across the surface using a drop spreader or broadcaster. Follow the manufacturer’s guidelines and add 2 to 4 pounds (4 to 5 kilograms) of infill per square foot or meter.
Use a stiff-bristled push broom or a mechanical power brush to work the sand into the roots, helping the turf blades stand upright and appear natural.
Bottom Line
Have you been struggling to install artificial grass in your home or commercial space? The guidelines above can help you install it effectively. However, it is recommended to consult a professional when looking for artificial grass installation services.
