What Do You Put Under Artificial Grass?

Artificial grass is a great option for homeowners who want a lush, green lawn that requires little maintenance. The top layer of artificial turf may be perfect, but what lies below is critical to the performance and longevity of your synthetic lawn. The base layer must be properly prepared to ensure good drainage, stability, and durability. Here is a complete guide to what you should put under artificial turf.

1. Sub-base Preparation


First, you will need to dig up the area where you intend to install artificial grass. This usually involves removing between 3 and 4 inches of soil in order to accommodate the sub-base material. This step is crucial to ensure that your lawn sits flush against the surrounding surfaces and has enough depth for sub-base and turf.

Weed Membrane

Install a weed membrane before laying down any material. This layer will prevent weeds from growing through your artificial grass. It will reduce maintenance and keep your lawn looking great.

2. Sub-base Materials

Gravel or Crushed Stone

It is important to have a solid foundation in order to ensure drainage and support the artificial turf. Create a stable base by using crushed stone or gravel. Use a plate compactor to compact a layer of 2-3 inches. This layer is stable and allows water to drain effectively, preventing puddles.


The crushed stone is followed by a layer sharp sand. This layer of sand, which is typically 1 inch thick and smooths the surface, provides a stable, even foundation for the grass. This layer also helps with drainage and secures the grass.

3. Geotextile Membrane

Secondary weed Barrier

Over the sand, you can add another layer of geotextile membrane. The second weed barrier ensures that weeds cannot penetrate to the surface.

4. Laying Artificial Grass

Final Preparation

Make sure the base layers of the artificial grass are compacted and leveled before laying it. Unevenness can have a negative impact on the performance and appearance of the turf. Roll the artificial turf over the base and make sure it is firmly seated.

Securing the grass

Landscape staples or adhesive can be used to secure the grass around the edge. Be sure to join the seams correctly in order to avoid visible lines.

Infill Material

The grass is then brushed with an infill such as rubber granules or silica sand. This step increases the weight of the turf and keeps the fibers in place. It also enhances the look and feel.


Under the surface lies the key to a beautiful, durable artificial lawn. All of these components are essential: proper excavation, high-quality sub-base, weed barriers, and careful installation. Follow these steps to enjoy a lush green lawn for many years.
