Artificial turf has emerged as a popular landscaping solution for Aussie homeowners seeking a low-maintenance, drought-proof option. The process of laying fake grass on soil is a straightforward DIY job that can transform your yard into a lush green haven, empowering you to take control without the hassle. 

This guide has step-by-step instructions and expert tips for installing artificial grass on dirt, ensuring the success of your job.

Disclaimer: We always recommend hiring a professional landscape construction expert (like us) to ensure your turf is laid in the best way possible, ensuring longevity and safety. DIY installation can save on labour costs, but it’s important to note that improper installation can lead to issues such as poor drainage, uneven surfaces, and premature wear and tear.

Pre-Installation Considerations for Fake Grass on Dirt

Before starting the installation process, consider a few key factors to ensure the success and longevity of your artificial turf installation. 

Here’s what you need to keep in mind:

Preparing the Area

Before you start laying your fake grass, proper ground preparation is key to getting the best results and longevity of your new lawn. For a comprehensive guide on how to install fake grass, including essential preparation and planning steps, make sure to measure the area and consider potential landscaping features.

Remove Existing Grass and Weeds

First remove the top layer of grass and soil to a depth of 7-10cm using a turf cutter or spade. This will give you a level base for your artificial turf. To get rid of any existing weeds, spray the area with a glyphosate based weed killer at least 2 weeks before installation. This will stop weeds from growing through your new synthetic lawn and ensure a smooth surface to install artificial turf.

Level and Compact the Soil

Once you’ve removed the grass and weeds, use a rake or spade to level out any bumps or dips in the soil. A level surface is critical to prevent water pooling and for your fake grass to look smooth and even. After levelling, compact the soil using a vibrating plate compactor or hand tamper. This will give you a stable base that will stop the turf from shifting or sinking over time, which is essential when installing artificial grass.

Install a Sub-Base

To improve drainage and prevent future settling, add a 7-10cm layer of crushed rock or road base to the compacted soil. Spread the material evenly and compact it down using a plate compactor. Then add a 1-2cm layer of bedding sand over the compacted sub-base and level it out using a screed. The bedding sand will give you a smooth surface for installing artificial turf.

Lay a Weed Barrier (Optional)

If you want extra protection against future weed growth, consider laying a geotextile weed mat over the levelled area. This permeable fabric allows water to drain through while preventing weeds from growing. Secure the mat in place with landscaping pins.

Installing the Artificial Grass

Now the ground is prepared, you can lay artificial grass and secure your synthetic turf for a beautiful low maintenance lawn.

Unroll and Position the Grass

Unroll the fake grass rolls onto the prepared surface and let them settle for a few hours. This will help reduce creasing from the packaging. When positioning the turf, make sure all rolls are laid in the same direction to maintain a uniform look.

Trim the Edges

Using a utility knife, cut the turf around any edges or obstacles, such as garden beds or paths. Leave a small gap (3-5mm) between the turf and hard surfaces for expansion and contraction due to temperature changes.

Secure the Turf

To stop your artificial grass from shifting, secure the edges every 20-30cm using 15-20cm galvanized nails or landscaping pins. For larger areas, place additional pins throughout the centre of the turf every 50-100cm.

Join Multiple Pieces (If Applicable)

If your lawn requires multiple pieces of artificial turf, lay them together with the edges touching. Use outdoor tape and adhesive or seaming tape to join the pieces together. Follow the manufacturers instructions for best results.

Finishing Touches

Now you’ve completed the installation of your artificial lawn. Here are the final steps to get a polished look.

Brush the Grass Blades

Using a stiff broom or power broom, brush the grass blades against the grain. This will make the blades stand upright, just like natural grass.

Infill

To weigh down the turf, support the grass blades and give it a more realistic feel, spread silica sand infill evenly across the artificial grass at 6-8kg per square meter. Use a broom or rake to brush the infill into the grass blades, evenly.

Maintenance and Care for Fake Grass on Soil

Artificial grass requires minimal maintenance compared to natural lawns but regular care will keep it looking great for years to come.

Key Takeaways

• Prepare the ground by removing grass, levelling the soil, installing a sub-base and laying a weed barrier
• Unroll and position the grass, all rolls in the same direction
• Trim edges, secure with pins and join multiple pieces if needed
• Brush the grass blades and apply silica sand infill for a natural look and feel
• Maintain your artificial lawn with regular cleaning and care
