Can I Install New Artificial Grass Over Existing Turf?

Can I install new artificial grass over existing turf? Yes, installing new artificial grass over existing turf is possible in certain situations, but it requires careful consideration and preparation. Here’s what you need to know.

Installing new artificial grass over existing turf can be a practical and cost-effective solution for rejuvenating outdoor spaces. However, several factors need to be considered to ensure a successful installation process and optimal long-term performance. Let me explain the steps involved in installing artificial grass over existing turf, potential challenges, and frequently asked questions to help you make an informed decision.

Assessing the Feasibility

Before embarking on the installation process, it’s essential to assess the feasibility of installing new artificial grass over existing turf. Consider the following factors:

Condition of the Existing Turf

Evaluate the condition of the existing turf to determine if it is suitable for installation. Ensure that the turf is relatively flat, free of major damage, and has adequate drainage.

Compatibility of Materials

Ensure that the new artificial grass is compatible with the existing turf and suitable for installation over it. Some types of artificial grass may not adhere well to certain surfaces, so it’s essential to choose the right product.

Preparation Steps

Once you’ve determined the feasibility of installing artificial grass over existing turf, follow these preparation steps:

Clearing Debris

Thoroughly clean the existing turf to remove any debris, vegetation, or organic matter. Use a leaf blower, rake, or power broom to clear the turf effectively. It may be wise to add some sort of substrate to make it even and more sturdy when stood on. Using a compactor (Wacker plate) or a manual tamper to compact it and level it.

Addressing Drainage Issues

Check the drainage system of the existing turf to ensure that water can flow freely and efficiently. Make any necessary adjustments or improvements to the drainage system before proceeding with the installation.

Adding a Weed Barrier

To prevent weeds from growing through your new artificial grass, consider adding a weed suppressing membrane over the existing turf. You may want to use some sub-base as well. This will help suppress weed growth and provide a stable base for the artificial grass.

Installation Process

Once the preparation steps are complete, you can proceed with the installation process:

Laying Out the Artificial Grass

Carefully lay out the new artificial grass over the existing turf, ensuring that it is positioned evenly and securely, with the pile facing the property, ideally. Use adhesive or seaming tape to join the seams and secure the edges of the artificial grass.

Trimming and Shaping

Trim and shape the artificial grass as needed to fit the contours of the area. Use a sharp utility knife like a Stanley knife to cut the grass to size, ensuring clean and precise edges.

Securing the Edges

Secure the edges of the artificial grass with landscape staples or galvanised nails to a sturdy structure, like a treated timber frame, to prevent shifting or movement. Use a knee kicker if possible to stretch it out, to avoid creases. Ensure that the edges are securely anchored to the structure for a stable installation.

Considerations and Limitations

While installing new artificial grass over existing turf can be a convenient option, there are some limitations and considerations to keep in mind:

• Compatibility: Ensure that the backing of your new artificial grass is not too soft and bendy. Be aware that in hot seasons, the artificial grass turn to soften a bit, hence the need to use the substrates as a base.
• Surface Preparation: Proper surface preparation is essential for a successful installation. Neglecting to use the right substrate can result in problems with the artificial grass installation.
• Long-Term Performance: Consider the long-term performance and durability of the installation. Factors such as a sturdy base, (using MOT type 1 with sharp sand on top or granite dust), drainage, compaction, and stability may impact the lifespan of the artificial grass.
