The Most Important Part You’ll Never See
Whether you're building a patio, laying turf, installing a wall, or prepping for sod — everything rests on the base. The base material is what holds it all together, and if it’s wrong (or missing), your whole project can fail in months. Here’s why it matters, what we use, and how a proper base makes all the difference.
1. Base Material & What It Actually Does
1. Base Material & What It Actually Does
Compacted stone, gravel, or fines placed under patios, turf, or walls
Supports heavy loads and prevents settling
Improves drainage to reduce freeze-thaw damage
Provides a smooth, level surface for final layers
Protects against frost heave in cold climates
This is the #1 factor in whether a patio lasts 10+ years—or fails in 1.
2. Common Base Materials (Colorado Examples)
2. Common Base Materials (Colorado Examples)
Class 6 Road Base – crushed rock + sand + fines; compacts tightly; ideal for patios, driveways, and walls
Crusher Fines – tiny crushed rock particles; smooth finish; best for pathways or between pavers
Clean ¾” Gravel – excellent drainage; used under synthetic turf and French drains; not a surface layer
The wrong base leads to drainage issues, movement, and expensive repairs.
3. Recommended Base Depths by Project
3. Recommended Base Depths by Project
Paver patio – 4"–8" of Class 6 base + 1" of bedding sand
Retaining wall – 6"–12" of compacted base with a leveling pad
Synthetic turf – 3"–4" of clean ¾” gravel over a weed barrier
Driveway – 8"–12" of heavily compacted road base
Sod lawn – 2"–3" of nutrient-rich soil blend (not gravel)
Pro tip: Always compact in 2-inch layers (called "lifts") to avoid settling and shifting over time.
4. What Happens Without a Solid Base
4. What Happens Without a Solid Base
Pavers shift and settle, creating hazards
Turf ripples, holds water, or sinks over time
Walls lean or collapse from lack of support
Water pools where it shouldn’t
Materials wear unevenly or crack
We’ve replaced entire patios and turf installs due to shortcuts on base prep.
5. Watch for Price Cuts That Skip Base Prep
5. Watch for Price Cuts That Skip Base Prep
Some quotes skip base entirely or skimp on depth
Thin layers or poor-quality materials may be cheaper—but won’t last
Unwashed gravel and lack of compaction lead to future failures
We always itemize base prep because it’s not optional—it’s the foundation of the job.
