- Transition Sand (middle layer) for Biofiltration system installations
- Drainage applications requiring a high-quality, durable free-draining washed sand
Benedict SmartMix®10 Biofiltration Transition Sand (NbS)
Benedict SmartMix® 10 Biofiltration Transition Sand (NbS) is manufactured to comply with CRC Adoption Guidelines for Stormwater Biofiltration Systems (July 2015) and Blacktown City Council – Bioretention Specification (Feb 2022), as the transition sand (middle layer). It is a medium to coarse washed sand with a targeted particle range to assure excellent hydraulic conductivity (that is higher than the biofiltration filter media that sits above it).
The biofiltration profile comprises of very specific layers with the necessary characteristics to enhance hydraulic conductivity and ensure optimal bridging. Our SmartMix® Biofiltration profile comprises of three individually manufactured layers that all work together:
SmartMix® 10 Biofiltration Transition Sand (NbS) is sold in conjunction with Benedict SmartMix® 9 Biofiltration Filter Media (NbS) and SmartMix®11 NoFines™ Drainage Gravel (NbS).
