Recommended Depth & Base Specifications for Horse Arena Gravel Sub-Base Calculator
Selecting the proper installation depth is the single most critical factor in preventing premature rutting, sinking, or weed breakthrough.
| Layer / Application | Recommended Depth | Stone Aggregate Type | Contractor Notes |
|---|---|---|---|
| Subgrade Preparation | 1-2% Slope | Laser Graded Clay/Loam | Crowned or single-sloped subsoil foundation with drainage ditches. |
| Compacted Base Aggregate | 4 to 6 Inches | Crusher Run / Road Base | Heavy roller-compacted to prevent horse hooves from breaking into soft subsoil. |
| Top Footing Layer | 2 to 3 Inches | Angular Sand / Polymer Mix | Provides traction, cushion, and energy return for horses. |
💡 Contractor Installation Pro Tips
- The base must be as hard and smooth as asphalt before applying top footing; any soft spots will cause severe tripping hazards for horses.
- Ensure a 1% slope across outdoor arenas to shed heavy rain without pooling on the base.
