Available now from Green Roof Technologies , the VersiDrain 25P water retention and drainage tray facilitates the construction of extensive green roofs to reduce radiant heat from hard roof surfaces.

The VersiDrain 25P water retention and drainage tray is a lightweight, cost-effective drainage system comprised of a number of cells that work to both store and drain water in landscape applications.

Manufactured from UV-stabilised high density polyethylene, VersiDrain 25P water retention and drainage trays promote the growth of healthier plants and reduce irrigation frequency.

The unique design of these drainage systems allow excess water to be efficiently drained away, while at the same time water is being stored in a network of mini reservoirs across the entire irrigated area. In dry periods the water soluble nutrients stored in the cells of the VersiDrain 25P water retention and drainage tray are returned to the soil.

The cells in the VersiDrain 25P water retention and drainage tray are interconnected by channels that allow water to flow between the cells, whilst holes in the channels ensure fail-safe drainage under extreme conditions.

The high compressive strength of the VersiDrain 25P water retention and drainage tray protects the waterproofing membrane and effectively supports the weight of the growing media and plants.

Key advantages of VersiDrain 25P water retention and drainage trays include:

  • healthier plants
  • reduced irrigation frequency
  • resistance to ground chemicals and biological attack
  • root-impenetrable
  • improved protection of waterproofing membrane.
Typical applications for these water retention and drainage trays include extensive green roofs, intenseive landscape roof decks, and planter boxes.
