Stormwater Control
PaveDrain - Stormwater's Arch Enemy

Structural and Environmental Benefits

The PaveDrain System combines modern day functionality and a structural concept used for centuries to create the revolutionary permeable paving solution. PaveDrain incorporates a patented arch design in the middle of an articulating concrete block to create an internal storage chamber that can be filled with stormwater runoff while simultaneously providing strength for heavy vehicular loads. The PaveDrain System is designed to be a critical component of Low Impact Development (LID) allowing for the infiltration of stormwater runoff … onsite. The PaveDrain System is a Permeable Articulating Concrete Block/Mat (P-ACB/M) that provides environmental benefits as a designated solution for compliance with local regulatory stormwater requirements. The durability and performance, in terms of life-cycle costs, make it the prudent alternative to all other paving surfaces. PaveDrain and its aggregate bedding stone is engineered to create a natural, vertical infiltration path, that recharges local groundwater all while using nature’s inherent ability to filter first flush pollutants. This allows for a reduction or elimination in stormwater infrastructure while minimizing the environmental impact. In addition to effectively managing stormwater runoff the PaveDrain System is also being developed using recycled materials which will make it one of the leading green technologies for stormwater management. PaveDrain works.


ASTM Standards & ADA Compliance

The PaveDrain System meets the requirements of ASTM 06684-04 and is recognized by the USEPA as a structural Best Management Practice (BMP) for stormwater infiltration. The Americans with Disabilities Act (ADA) Design Guidelines require that surface openings shall not exceed y, and shall be firm, stable, and slip resistant. The PaveDrain System easily exceeds all these requirements by incorporating a 3/8″ gap between individual PaveDrain blocks.

Infiltration Report

The PaveDrain System was tested and documented by American Excelsior Company’s ErosionLab to help better understand its infiltration capabilities. It was installed over two plots that contained an identical six inch aggregate bedding layer, but different underlying soils consisting of clay and sand. The plots were exposed to increasing simulated one hour duration rainfall events (i.e. 4″, 6″ and 8″) until runoff was measured.

Maintenance and Repair

The PaveDrain System is easy to maintain using industrial vacuuming equipment, if needed. If a significant amount of sediment accumulates in the aggregate bedding stone, PaveDrain is the only system that can be can be mechanically lifted out allowing for the subgrade to be cleaned and then the same mats re-installed. Repair of individual PaveDrain blocks can be accomplished without removing the (mat) cables.
