About this file
This is a sole source justification letter from K.B. Industries, Inc. submitted to Sarasota County, Florida, for the renewal of procurement for KBI FLEXI-PAVE, a proprietary porous pavement material. The product is manufactured from recycled passenger tires combined with stone aggregate and a proprietary binder, mixed on-site and available for use within 24 hours of application. KBI FLEXI-PAVE is designed for installation over various substrates, primarily natural earth, and can accommodate slopes up to 30 percent. The material is suitable for high-traffic pedestrian areas including foot, bicycle, wheelchair, and rollerblading use, as well as light vehicular traffic not exceeding 35 miles per hour. The material is available in multiple color options and provides impact absorption, flexibility to substrate movement, sound absorption, and slip resistance meeting ADA compliance standards. Installation is performed only by certified KBI installers who warrant the material meets all specified characteristics.
The sole source justification is based on KBI FLEXI-PAVE's unique combination of testing compliance and performance characteristics that distinguish it from competing products in the porous pavement technology market. The material must meet rigorous ASTM and industry-specific testing standards including freeze-thaw resistance through 300 cycles, permeability testing per ASTM 565, slip resistance requirements, accelerated weathering, Hamburg loaded wheel testing, creep testing, resilient modulus testing, and sound absorption testing. The material maintains a dynamic flexible void capacity of 18 to 22 percent for precipitation permeability and demonstrates resistance to transmission fluids, hydraulic fluids, brake fluids, gasoline, diesel, saltwater, oil, chlorine, ozone, bromine, and muriatic acid. Sarasota County reserves the right to cancel this sole source procurement and conduct a competitive solicitation if respondents demonstrate the ability to supply the same or substantially similar products or services.
