What’s the Best Sub Base for Artificial Grass? A Comprehensive Guide

A few years ago, if you had you asked me, “Hey, what’s the best sub base for artificial grass?” my response would definitely have been one of those deer-in-the-headlights looks. (That’s not uncommon for me, but I digress.) Since then, I’ve received some expert synthetic turf schooling. So now I get to be the sub base sensei.

Identifying your ideal sub base material is crucial for turf’s longevity and performance. Artificial grass is a investment. You want to see some returns in the long run, right? So, for an accurate answer to this question, you need to understand why sub base is important. You need to know what types are available. And you need to understand the strengths and shortcomings of each. I’ve covered all of this, as well as a few important tips about installation and maintenance. Sub base school is now in session, grasshopper.

Best Sub Base for Artificial Grass, the Basics:

• • A well-prepared sub base is crucial for a long-lasting, even artificial lawn
  • The most common types are crushed stone, decomposed granite, and recycled aggregates
  • Each material has its strengths, making them more useful for different turf applications
  • Always consider your specific needs, budget, and local climate when choosing a sub base

So, why is sub base so dang important? Well, imagine you’ve just laid down your brand-spanking-new artificial turf. It looks like a million bucks. You enjoy it for a few wonderful weeks. Then you notice some funky wrinkles and puddles forming. What?! You poured cash and sweat into that thing. Why does it look so bad so quickly? That’s what happens when you skimp on the sub base, my friends.

The Importance of a Proper Sub Base for your Artificial Grass

A well-prepared sub base is the unsung hero of any successful artificial grass installation. It’s like the foundation of a house. If it’s not done right, the whole thing could come crumbling down. Do you begin to see why you want to choose the best sub base for your artificial grass, student?

Here’s what you can expect from a good sub base:

• • Stability: Keeps your turf looking smooth and even for years to come
  • Drainage: Prevents water from pooling and damaging your turf
  • Longevity: Extends the lifespan of your artificial grass

I know it can be tempting. But I’ve seen the results of corner-cutting here. One time a customer wanted to save a few bucks by using some gravel they had from a previous courtyard project. It won’t shock you to learn it didn’t go well. The turf was lumpy. The drainage was a mess. They ended up replacing their new artificial grass in a few seasons. Take it from me: always invest in a quality sub base.

Types of Sub Base Materials

Congratulations. You’ve taken the first sub base step. Let’s keep going, Neo. Here are a few of the most common materials you can choose from.

1. 1. Crushed Stone (for example: Class II Road Base)
      – A mix of gravel and sand
      – Provides excellent stability and drainage
      – Budget-friendly option
   2. Decomposed Granite
      – Consists of granite pieces, gravel, and sand
      – Ideal for putting greens due to its smooth finish
      – More expensive than crushed stone
   3. Recycled Aggregates
      – Made from recycled concrete and other materials
      – Eco-friendly option
      – Can be used in combination with other sub base materials

So, what’s the best sub base for artificial grass? Unfortunately, there’s no one-size-fits-all answer. There’s only a best for you. To answer that, ask yourself a few questions. What is your budget? What is the purpose of your turf? And what is your local climate?

For example, maybe you’re installing a putting green. Decomposed granite is the way to go for that silky-smooth finish. But what if you’re working with a tighter budget? Crushed stone like Class II road base is a solid choice that still provides excellent stability and drainage.

Preparing and Installing Sub Base

You’ve picked out your sub base material. Now it’s time to get your hands dirty (figuratively speaking, of course – we recommend wearing gloves). Here’s a quick rundown of the installation process:

1. 1. Excavate the area to a depth of 3-4 inches
   2. Compact the soil to create a stable foundation
   3. Install a weed barrier (optional but recommended)
   4. Spread your chosen sub base material evenly
   5. Compact the sub base using a plate compactor or hand tamper
   6. Test for stability and proper drainage

Now, I know what you’re thinking: “Mark, this sounds like a lot of work!” And you’re right, it is. It’s worth it in the long run. This is one of those “You get out of it what you put in” situations. In a big way. A properly installed sub base will save you a world of headaches down the line.
