Project Design Calculators
For preliminary base calculations with criteria base on American Society of Civil Engineers 58-16: Structural Design of Interlock Concrete Pavement for Municipal Streets and Roadways.
Calculate the base, subbase and rainwater harvest capacity based on rainfall amounts per hour.
Infiltration Rate OnSite
Perform on site tests to calculate the current infiltration rate of your pavers. This data is in accordance with ASTM C1781.
Infiltration Rate Design
Calculate the infiltration of water or stormwater though the Unilock Permeable Paver used in your design based on rainfall intensity in your area.
