Can TRUEGRID Pavers Handle Steep Slopes?
TRUEGRID pavers are engineered to accommodate slopes with remarkable adaptability. The manufacturer specifies a maximum recommended slope percentage of up to 20 degrees, providing flexibility for challenging terrain installations.
Slope Performance Breakdown
| Slope Angle | Installation Requirements | Stability Factors |
|---|---|---|
| 0-8 degrees | No additional anchoring needed | Standard installation |
| 8-20 degrees | Potential anchoring required | Additional stabilization techniques |
What Preparation Ensures Successful Steep Driveway Installation?
Base Preparation Strategies
Successful TRUEGRID paver installation on steep drives depends on meticulous groundwork:
- Sub-base Material Selection
- Use crushed aggregate meeting ASTM No. 57 specifications
- Consider materials like crushed concrete, shale, or limerock
-
Ensure material porosity exceeds 0.32
-
Geotextile Fabric Implementation
- Install between subgrade and base material
- Provides weed barrier and separation layer
-
Enhances overall system stability
-
Compaction Techniques
- Compact base material in 6-inch lifts
- Achieve 95% Modified Proctor density
- Ensures uniform load distribution
How Do TRUEGRID Pavers Manage Water on Steep Surfaces?
TRUEGRID’s exceptional drainage capabilities make it ideal for sloped surfaces:
- Infiltration rates exceed 800 inches/hour
- Prevents surface water runoff
- Stores water in aggregate sub-base
- Allows gradual soil infiltration
What Load Capacities Can Steep Driveways Expect?
