New Features

aluminum 415x295


Aluminum is a great choice for bioretention. It is lightweight, adding less to the overall load. It is easier to deliver, assemble and complete installation. It’s also friendly on the environment, requiring less energy to deliver, build, and recycle.

Splash Box

Our Splash Box and Level Spreaders are accessories available for both GFRC and Aluminum Bioretention Planters. The Splash Box has been thoughtfully designed to be easy to install, able to be located anywhere in the planter, and has a removable tray for easy clean-out.

Level Spreader

Level up with this mini aqueduct, which has unique perforations along the spreader for even water distribution. The Level Spreader distributes rainwater evenly across the planter, slowing down the flow.

Bioretention Planters

Our Bioretention Planters are pre-built and installed on-site to collect stormwater from drain leads/downspouts. Plants and media filter water, removing organic and inorganic solids, and slowly release the water into the storm drains, reducing peak discharge rates.
