I walked the exhibitor floor at the National Green Building Conference & Expo in Salt Lake City and found a few interesting products like this dRain Joint by Arvis Eco. This is a rainwater management product — specifically, an inserted drainage channel — for pour-in-place surfaces in driveways and parking lots.
The ADA-compliant product is made with aluminum and gives storm water a path to a sub-surface drainage bed. From there, water can be collected or left to seep back into the ground.
dRain Joint is sold by Indiana-based Arvis Eco and can be delivered in 2-4 weeks. The product processes about two gallons of water per minute per linear foot and installs at the same time as the surface installation.
