VersiDrain® BST

What is VersiDrain® BST

VersiDrain® BST is an extensive green roof planting tray used to create biosolar flat roofs. The modular trays are made from UV-stabilised recycled polypropylene, which makes them lightweight and robust.

Wall extenders can be affixed on any of the four sides of each tray to accommodate deeper planting depths and the possibility of establishing a border around the green roof.

VersiDrain® BST creates a monolithic reservoir on the green roof, allowing maximum greenery and higher efficiency of solar energy generation.

Rainwater that falls onto the unsheltered tray filters through the planting media and is collected in the tray’s reservoir. As the rainwater levels out in the reservoir, excess water is distributed to adjacent trays sheltered by solar panels or roof structures. This ensures adequate irrigation for the entire green roof.

Modular Extensive BioSolar Tray Planting System

Self-Watering

QwickWick® conveys water to planting media, ensuring they are kept moist to promote plant growth, decreasing the need for frequent irrigation.

Modular Extensive BioSolar Tray Planting System

Fittings Around Obstacles

Trays can be connected with 50 mm pipe fixings to speed up water distribution among adjoining trays.

Modular Extensive BioSolar Tray Planting System

Linked Reservoirs

Rainwater collected from unsheltered trays is distributed evenly across the VersiDrain® BST system with proprietary Continuous Joiner.

Create Maintenance Paths & Walkways

Trays may be filled with gravel and joined with adjacent trays to form maintenance paths and walkways.

Modular Extensive BioSolar Tray Planting System

  • Vegetation and solar panels complement and do not compete for roof space
  • Rainwater collected from unsheltered trays is distributed to sheltered and obstructed trays
  • Configurable to spaces with solar panel installations
  • Optimised water supply from a single source compared to drip lines, where supplementary irrigation is required
