What is the minimum aggregate base thickness required for installing concrete pavers for driveways?

The minimum aggregate base thickness required for installing concrete pavers for driveways is generally recommended to be 6 inches. This thickness provides a solid support structure that can withstand the weight of vehicles, ensuring proper load distribution and reducing the risk of settling or shifting over time.

An aggregate base of this thickness allows for adequate drainage, which is critical in preventing water accumulation beneath the pavers. Proper drainage helps to reduce the risk of frost heave in colder climates and prevents the base from becoming saturated, which could lead to instability. Additionally, a 6-inch base creates a strong foundation that enhances the durability and longevity of the paver installation, allowing it to handle the stresses of traffic without cracking or shifting.

While some other thickness options might be proposed, they may not align with standard practices for driveway installations, which prioritize both stability and drainage in their recommendations.
