Artificial grass has become a popular choice for many homeowners and landscapers, offering the lush appearance of natural grass without the intensive maintenance. Laying artificial grass over soil is a feasible task, but it requires careful preparation and execution.
Laying Artificial Grass on Soil
Laying artificial grass on soil is a process that involves several key steps to ensure a successful and long-lasting installation. Here’s a comprehensive guide on how to lay artificial grass on soil:
Clear the Area: Begin by removing any existing natural grass, weeds, and debris from the area where you want to install the artificial grass. This can be done using a sod cutter, shovel, or any other suitable tool. Ensure that the area is completely cleared and free from organic material.
Prepare the Base: Once the area is cleared, the next step is to create a stable base. This involves levelling the soil to prevent any uneven surfaces under the artificial grass. Use a rake or similar tool to level the ground. After levelling, compact the soil to create a solid base. This can be done with a roller or a vibrating plate compactor.
Install a Weed Barrier: Laying down a weed barrier is an optional but recommended step. This fabric layer helps prevent weeds from growing through the artificial grass. Roll out the weed barrier fabric over the compacted soil and secure it with landscape staples.
Apply a Layer of Aggregate: On top of the soil or weed barrier, add a layer of aggregate material, such as crushed rock or gravel, about 2-3 inches deep. This layer is crucial for drainage and provides a firm foundation for the artificial grass. Spread the aggregate evenly and then compact it to ensure a flat and stable surface.
Install a Layer of Sharp Sand: Over the aggregate layer, add a thin layer of sharp sand. This helps to level out the surface further and provides a smooth base for the artificial grass. Compact and level the sand layer as well.
Roll Out the Artificial Grass: Unroll the artificial grass over the prepared base. Allow some time for the grass to settle and flatten out, especially if it was tightly rolled up during transport. Make sure the grass is positioned correctly and covers the entire area.
Trim and Join (if necessary): If your installation involves multiple pieces of artificial grass, they need to be joined together. Trim the edges of the grass to fit the area and use joining tape and adhesive to connect the pieces securely. Make sure the fibres of the grass are not caught in the adhesive.
Secure the Edges: Use landscape staples or ground pins to secure the edges of the artificial grass to the ground. This prevents the turf from shifting or lifting.
Add Infill (if required): Some types of artificial grass require an infill to help keep the fibres upright and add extra cushioning. Spread the infill evenly over the grass and then brush the grass fibres to distribute the infill and help them stand upright.
Final Brush and Clean: Once the grass is installed and secured, use a stiff brush to lift the fibres and give the grass a more natural look. Clean off any debris or leftover material from the installation process.
By following these steps, you can successfully install artificial grass over soil, creating a durable and aesthetically pleasing outdoor space.
Creating the Best Base for Artificial Grass
After preparing and compacting the soil, it’s important to create a suitable base for the artificial grass. A common approach is to use a layer of crushed rock or gravel, about 2-3 inches deep. This layer aids in drainage and provides a firm foundation. It’s important to ensure that this layer is also levelled and compacted. Over the gravel, a layer of sharp sand is spread and compacted. This sand layer helps in fine-tuning the level and provides a smooth surface for laying the artificial grass.
The Role of Underlay in Artificial Grass Installation
The question of whether an underlay is needed for artificial grass often arises. While not always necessary, an underlay can provide several benefits, especially when laying artificial grass over soil. It can aid in drainage, provide a layer of cushioning, and help with levelling. For gardens or play areas, a shock-absorbent underlay might be considered to provide additional safety. However, it’s important to ensure that the underlay does not impede drainage, as proper water runoff is crucial for the longevity of the artificial turf.
Best Time of Year to Lay Artificial Turf
Choosing the right time of year to lay artificial grass can impact the ease of installation and the initial appearance of the turf. Generally, mild weather conditions – typically in late spring or early autumn – are ideal. During these periods, the ground is neither too hard nor too soft, which facilitates easier soil preparation and base laying. Extreme temperatures, whether hot or cold, can make the installation process more challenging.
Longevity of Artificial Grass
The lifespan of artificial grass is a significant consideration, and fortunately, it is known for its durability. High-quality artificial grass can last anywhere from 10 to 20 years, depending on the level of foot traffic and the quality of the installation. Factors such as UV resistance and the material’s quality play a role in determining how long the grass will retain its color and integrity. Regular maintenance, although minimal compared to natural grass, is still important. This includes occasional brushing to keep the blades upright and rinsing to remove dust and debris.
In summary, laying artificial grass over soil is a feasible project that can transform your outdoor space with a low-maintenance, aesthetically pleasing lawn. The key steps involve preparing the soil, creating a solid base with appropriate materials, considering the use of an underlay for additional benefits, and choosing the right time of year for installation. With proper installation and minimal maintenance, artificial grass can offer a long-lasting, green solution for your garden or landscape. By following these guidelines, homeowners can enjoy the lush appearance of natural turf with significantly reduced upkeep, making artificial grass a practical and attractive option for many outdoor spaces.
