Instructions
The imix Eco Pave Pervious Calculator is provided to help you estimate three key pieces of engineering information.
Step 1: The total water capacity of Eco Pave with your specifications.
Step 2: The time needed for water at capacity to infiltrate the soil.
Step 3: This is a design calculator to determine the depth and tonnage of aggregate needed to hold your specification of water. It also calculates the time needed for water, at capacity, to infiltrate the ground.
In each calculation, the imix Eco Pave Calculator is meant to be a general design guide and should not supersede any engineer’s report regarding your specific project.

Recommendations
We recommend that imix Eco Pave be placed at the following depths based on usage.
Foot traffic only – 4 inches
Light vehicle traffic (no trucks) - 6 inches
Heavy vehicle traffic – 8+ inches.
Aggregate depth is calculated on a 1:1 concrete to subbase profile in this application. Greater depths may be needed in your particular application. To contact an IMI representative, click here.
