Artificial Grass Sub Base: Everything You Need to Know

Introduction

Hook with a Benefit: Imagine a lush, green lawn that requires no watering, mowing, or fertilizing. Artificial grass offers this and more, but to achieve a flawless look that stands the test of time, the secret lies beneath—the sub-base.

**** Many homeowners mistakenly believe that laying artificial grass is as simple as rolling out a carpet. This misconception can lead to uneven surfaces, poor drainage, and ultimately, a disappointing lawn that doesn't live up to its promise.

The solution is a well-prepared sub-base. This foundational layer ensures your artificial grass remains smooth, drains well, and lasts for years. In this guide, you'll learn everything you need about artificial grass sub-base, from the best materials to the precise amounts needed.

By the end of this article, you'll be well-equipped to install a durable and beautiful artificial lawn, with insights into the best types of sub-base materials, installation tips, and common pitfalls to avoid.

Step #1: Understanding the Importance of a Sub Base

Why Do You Need a Sub Base?

Your artificial grass isn’t just a surface; it’s part of a system designed to mimic the natural feel of grass while offering superior durability. The sub-base is crucial for:

  • Stability: It prevents the grass from shifting or developing wrinkles.
  • Drainage: Proper drainage prevents water pooling, which can lead to mold and damage.
  • Longevity: A well-laid sub-base extends the life of your artificial grass.

Real-World Example: Think of the sub-base as the foundation of a house. Without a solid foundation, everything built on top is at risk.

Step #2: Choosing the Right Sub Base Material

Best Types of Artificial Grass Sub Base

  1. Crushed Miscellaneous Base (CMB)

    • Composition: A mix of sand, gravel, and recycled concrete or asphalt.
    • Benefits: Cost-effective and compacts well.
    • Drawbacks: Non-porous; may struggle with drainage.

  2. Class II Road Base

    • Composition: Similar to CMB but undergoes rigorous testing for strength.
    • Use Case: Ideal for commercial applications like sports fields.
    • Cost: Higher than CMB, not typically necessary for residential lawns.

  3. Decomposed Granite or Limestone Chippings

    • Composition: Natural stone derivatives.
    • Benefits: Superior drainage and a smoother finish.
    • Cost: More expensive but worth it for long-term performance.

Case Study: A homeowner in Arizona opted for decomposed granite for their backyard. Despite the initial higher cost, the improved drainage and aesthetics led to lower maintenance costs and a more appealing lawn.

Step #3: Calculating the Amount of Sub Base Needed

How Much Sub Base Do You Need?

The amount of sub-base required depends on the area and type of material. Here’s a quick guide:

  • For 100 square feet:
    • CMB: 1 to 2 tons.
    • Decomposed Granite: 1 to 1.5 yards.

Pro Tip: Always consult with a local artificial grass company to get precise measurements and recommendations. They can also provide delivery services, saving you the hassle of managing heavy materials.

Step #4: Installing Your Artificial Grass Sub Base

Step-by-Step Installation Guide

  1. Prepare the Area:

    • Remove existing grass and debris.
    • Level the surface to create a flat area.

  2. Lay the Sub Base:

    • Spread the chosen sub-base material evenly.
    • Compact it using a plate compactor to ensure stability.

  3. Check for Drainage:

    • Ensure the area slopes slightly to direct water away.
    • Test with water to verify effective drainage.

  4. Add a Laying Course:

    • Optional but recommended for a smoother finish.
    • Use granite dust or sand.

Metaphor: Think of this process like baking a cake. The sub-base is your batter, which needs to be smooth and even before adding the icing (your artificial grass).

Tips and Reminders

  • Choose the Right Material: Consider your climate and drainage needs. In wetter climates, prioritize materials that offer better drainage.
  • Don’t Skip Compaction: A well-compacted sub-base is crucial for preventing future issues.
  • Consult Professionals: When in doubt, hire professionals. They bring expertise and equipment that can save time and prevent costly mistakes.
