What to Put Under Artificial Grass: A Complete Guide

Artificial turf has become a popular choice for homeowners and businesses looking to create low-maintenance green spaces. It has the look and feel of natural grass without the need for constant watering, mowing and fertilizing. However, a common question that arises when installing artificial turf is what to put underneath it to ensure proper installation and longevity. In this guide, we’ll explore the various options for what to put under artificial turf and the benefits of each option.

1. Base material:
   The substrate is an important component of artificial turf installation. It provides a stable foundation for the lawn and aids in drainage. The most common substrate choices include crushed stone, decomposed granite, and gravel. These materials provide excellent drainage and stability, ensuring the artificial turf remains level and puddle-free.

2. Weed Barrier:
   To prevent weeds from growing through artificial turf, a weed barrier is essential. This can be a geotextile or weed membrane placed on top of the substrate. Weed barriers help keep the area beneath artificial turf clear of unwanted vegetation, ensuring a clean and low-maintenance surface.

3. Shock absorbing pad:
   For areas that require safety, such as playgrounds or sports fields, shock-absorbing pads can be installed under artificial turf. Shock-absorbing pads provide cushioning and impact absorption, reducing the risk of injury from falls. It is particularly beneficial in areas where children play, providing a softer, safer surface.

4. Drainage system:
   Proper drainage is essential for artificial turf to prevent water from pooling on the surface. A perforated pipe drainage system can be installed under the substrate to ensure efficient drainage. This is especially important in areas that experience heavy rainfall, as it helps prevent waterlogging and keeps artificial turf dry and usable.

5. Sand filling:
   Infill is often used to reduce the weight of artificial grass and provide stability. Silica sand is often used as filler because it helps support lawn blades and maintain their shape. Additionally, sand infill improves the drainage of artificial grass, ensuring that water can easily pass through the turf and into the substrate.

In summary, there are many options for what to put under artificial turf, each with a specific purpose to ensure proper installation and functionality. Whether it provides a stable foundation, prevents weed growth, enhances security, improves drainage or adds supportive infill, the materials placed under artificial grass play a vital role in its performance and longevity. By carefully considering the specific needs of the area where your artificial turf will be installed and choosing the right materials to place underneath it, you can ensure that your artificial turf installation is successful and long-lasting.
