Now that it’s clear why you must install a sub-base for your artificial lawn, you may find yourself wondering “What base do I need for artificial grass?” While only you can determine the best sub-base for artificial grass in your backyard, it’s important that you do your research to understand the different materials available. Artificial turf sub-base materials are broken down into three main categories:
- CMB – Made of recycled asphalt or concrete and a ¾” mixture of sand, gravel, or sand, a crushed miscellaneous base is an ideal option to lay between the ground and your artificial turf.
- Class II road base – Another option is Class II road base which goes through a rigorous testing process to ensure that it provides you with optimal consistency and durability. Because of this testing process, it often runs at a higher price point than CMB.
- DG – Decomposed granite is a sub-base composed of granite sand, gravel, and clay mixed together to create a stable and structurally sound layer for your synthetic lawn.
Of these three sub-base materials, CMB is the most commonly selected because of its cost-effectiveness and durability. While it’s the most popular, it necessarily doesn’t mean it’s the best choice for your backyard. Consult with an artificial grass lawn installation company before deciding on the best sub-base material for your project.
