What Do You Put Under Artificial Grass?
Artificial grass has become a popular choice for homeowners, businesses, and sports facilities due to its low maintenance and aesthetic appeal. However, to ensure your artificial turf looks great and performs well over time, it's crucial to prepare the ground properly before installation. The materials you put under artificial grass plays a vital role in its longevity, drainage, and overall appearance. Here’s a comprehensive guide on what you should put under artificial grass to achieve a beautiful, low-maintenance lawn.
1. Clearing and Excavating the Area

The first step in preparing your area for artificial grass is to clear the existing vegetation, rocks, and debris. This process involves removing any grass, plants, and roots to create a clean slate. Use a shovel or a sod cutter for larger areas to make the job easier.
Excavating the area to a depth of about 2-3 inches is essential. This depth allows enough room for the layers needed to support and stabilize the artificial grass. Proper excavation ensures that your artificial lawn will have a stable base and adequate drainage.
2. Weed Barrier Fabric

To prevent weeds from growing through your artificial grass, lay a weed barrier fabric. This permeable fabric allows water to pass through while blocking sunlight, which is essential for preventing weed growth. Using a high-quality weed barrier fabric ensures that your artificial grass remains weed-free for years to come.
Lay the weed barrier fabric evenly over the excavated area. Overlap the edges of the fabric by a few inches to ensure there are no gaps where weeds could penetrate. Secure the fabric with landscape staples or garden pins to keep it in place.
3. Base Layer: Crushed Stone or Decomposed Granite
The base layer is critical for proper drainage and stability. Crushed stone or decomposed granite is commonly used as a base material. These materials provide a solid foundation that allows water to drain through the artificial grass, preventing puddles and waterlogging.
Spread a layer of crushed stone or decomposed granite about 2-3 inches thick across the entire area. This base layer should then be compacted using a plate compactor to create a firm and stable surface. Proper compaction is essential to prevent the artificial grass from shifting or settling over time.
4. Sand Layer

A thin layer of sand is often added on top of the crushed stone or decomposed granite base. The sand helps to further stabilize the base and create a smooth surface for the artificial grass. This layer also aids in leveling the ground, ensuring an even installation.
Spread a layer of sand about 1/2 to 1 inch thick over the compacted base layer. Use a rake to distribute the sand evenly, then compact it with a plate compactor. Make sure the surface is level and smooth to avoid any bumps or depressions in the artificial grass.
5. Geotextile Fabric

For additional stability and separation between the base layer and the artificial grass, a layer of geotextile fabric can be applied. This fabric helps prevent the base materials from mixing with the artificial turf, which can improve the longevity and appearance of your lawn.
Geotextile fabric is also useful for enhancing drainage and preventing erosion. Lay the fabric evenly over the sand layer, overlapping the edges by a few inches. Secure the fabric with landscape staples or garden pins to keep it in place.
6. Edging Materials

Installing edging materials around the perimeter of your artificial grass area helps to keep the base materials in place and provides a clean, finished look. Edging can be made from various materials, including plastic, metal, or wood. Proper edging ensures that your artificial grass remains securely in place and prevents any shifting of the base layers.
Choose an edging material that complements your landscape design. Install the edging around the perimeter of the prepared area, securing it with stakes or nails. The edging should be flush with the ground surface to prevent tripping hazards and ensure a seamless transition between the artificial grass and surrounding areas.
7. Shock Absorption Layer (Optional)

In areas where children will be playing or for added comfort, an optional shock absorption layer can be installed beneath the artificial grass. This layer is typically made from foam or rubber padding and provides extra cushioning, making the surface safer and more comfortable.
A shock absorption layer can also reduce the impact on joints and muscles, making it ideal for sports fields and playgrounds. Install the padding over the geotextile fabric, ensuring it covers the entire area. Secure it with adhesive or staples to prevent movement.
8. Artificial Grass Installation
Once all the base layers are in place, the artificial grass can be rolled out over the prepared area.
Here’s a step-by-step guide to ensure a professional artificial grass installation:
1. Roll Out the Turf: Lay the artificial grass over the area, allowing it to acclimate for a few hours. This helps to reduce wrinkles and creases.
2. Trim the Edges: Use a utility knife to trim the edges of the artificial grass to fit the space. Ensure the cuts are clean and straight for a seamless look.
3. Join the Seams: If your installation requires multiple pieces of artificial grass, join the seams using seam tape and adhesive. Place the tape under the seams and apply the adhesive, pressing the edges together firmly.
4. Secure the Edges: Secure the edges of the artificial grass with landscape nails or staples, spacing them every 6-8 inches. This prevents the grass from lifting and shifting.
5. Brush the Grass Fibers: Use a stiff bristle brush to brush the grass fibers upright. This helps to create a natural look and feel.
6. Infill the Turf: Apply infill material, such as silica sand or crumb rubber, to the artificial grass. Infill helps to weigh down the turf, support the grass fibers, and improve drainage. Spread the infill evenly using a drop spreader, then brush the grass again to distribute the infill.
Conclusion
Proper preparation and layering are key to a successful artificial grass installation. By using a combination of weed barrier fabric, crushed stone or decomposed granite, sand, and optional geotextile and shock absorption layers, you can create a durable and aesthetically pleasing artificial grass lawn. Each layer plays a crucial role in ensuring proper drainage, stability, and longevity of your artificial grass, giving you a beautiful, low-maintenance lawn for years to come.
