Weeding, watering, cutting and fertilizing grass is both time-consuming and costly. This is why artificial grass installation has become increasingly popular in Toronto and the rest of the Greater Toronto Area (GTA). Artificial turf offers low maintenance requirements and great durability, making it a wise investment for those who want a low-effort backyard. Regardless of whether you are using artificial grass for your dogs or for landscaping, proper base preparation is crucial to its performance. The aggregate layer beneath the surface of your grass is a key foundational element that often goes unnoticed. Here is a breakdown of the importance of the aggregate layer beneath your grass.

What Is The Aggregate Layer?

artificial grass installationThe “aggregate layer” is the high-performance bedding that sits beneath your artificial grass in Toronto. This material is a crushed stone or gravel mixture. It is the bottommost layer upon which the weed barrier, padding, infill and of course, your turf sits. 

What Purpose Does the Aggregate Layer Serve?

The aggregate layer is an extremely critical component of artificial grass installation in Toronto and serves multiple purposes, including:

  • Supporting Proper Drainage: The crushed nature of aggregate allows water to flow through efficiently, preventing any kind of muddiness or water pooling when it rains.
  • Creates Stability: The aggregate layer helps give your artificial turf in Toronto some much-needed stability. It helps prevent shifting during seasonal changes and helps support foot traffic.
  • Enhances Turf Longevity: The aggregate layer beneath your turf reduces wear and tear on the synthetic grass backing. Overall, it contributes greatly to the longevity of your artificial grass, which is especially important if you own pet turf.
  • Supports Proper Installation of Other Layers: The aggregate layer is not the only one that sits beneath the surface of your artificial turf. Aggregate sits at the very bottom and helps support the other layers like the weed barrier and infill. 

How is The Aggregate Layer Installed?

Before artificial grass installation, your backyard or the designated area will be excavated so that 3-4 inches of the high-performance aggregate layer can be installed below the turf. This material is always compacted during installation to prevent shifting and to provide support to your turf. During the installation process, our team will perform multiple leveling checks to ensure that your turf is completely even and free of any dips once installed. Once this is complete, the other layers can be installed right before the turf.

Invest in Quality Artificial Grass With High-Performance Bedding

Ultimately, the performance and lifespan of artificial turf come down to what’s happening beneath the surface. A properly installed aggregate layer ensures strong drainage, a level finish, and long-term stability, helping your lawn look great and function properly year-round. Skipping or rushing this step can lead to uneven surfaces, poor water flow, and premature wear.
