Why Compaction Is Critical When Installing Artificial Turf

Artificial turf has become a popular solution for homeowners across Metro Atlanta who want a lush, low-maintenance lawn that looks great year-round. But what most people don’t see is the crucial work that happens before the turf ever goes down—especially when it comes to the gravel base.
One of the most important steps in the entire installation process is proper compaction of the 4-inch gravel base. Skipping or rushing this part can lead to serious issues that are expensive to fix later.
What Is the 4" Gravel Base?
Before artificial turf is installed, the existing soil is excavated and replaced with a 4-inch layer of crushed stone or gravel. This layer is the foundation of the turf system and provides:
Drainage
Stability
A smooth, level surface
But simply dumping gravel in place isn’t enough. That gravel must be compacted properly in multiple passes using professional equipment.
Why Compaction Matters
1. Prevents Settling and Sinkholes
If the gravel isn't tightly compacted, it will shift and settle over time, especially after rain. This leads to dips, soft spots, or even sinkholes beneath your turf.
2. Keeps Your Turf Flat and Smooth
A poorly compacted base will show through the turf—causing bumps, ripples, or uneven areas that ruin the look and feel of your lawn.
3. Improves Drainage
A well-compacted gravel base allows water to flow evenly through the turf and drain properly. Loose gravel traps water, which can cause odors, bacteria, and mold.
4. Extends the Life of Your Turf
Turf installed over a solid, compacted base holds its shape longer, resists movement, and reduces the chances of needing costly repairs down the road.

It takes time, but it’s the only way to ensure a durable, long-lasting result.
