Base Options & Overview

Crushed Stone Base Construction

Base Options     

Concrete:
Requires minimum thickness (typically 4") for non-weight bearing loads per the standards of the geographic region. 2% slope is recommended. Broom finish is recommended.

Asphalt:
Requires minimum thickness (typically 2") for non-weight bearing loads per the standards of the geographic region. 2% slope is recommended.

Crushed Stone:
Quarry process, crushed limestone… such as is used under asphalt roads. A homogeneous mixture of fine and medium stone is applied in multiple layers and compacted using a mechanical compactor and/or roller to provide an even plane. The crushed stone base must be tightly compacted and smooth. A 2% slope is recommended.

• 95% Standard Proctor Compaction (as per ASTM Test) is of critical importance.
• Stone for the base must be crushed so it compacts to the above standard, and should be a homogeneous mix of sizes. Please contact us for a copy of the crushed stone specification.
• Minimum depth of crushed stone base should be 4".
• Crushed stone base must be fully contained.
• A filter fabric is necessary for crushed stone bases only when tiles are installed. It is not used with Poured-in-Place or TurfTop Systems.
