What is VersiFlex®

VersiFlex® is an efficient drainage cell designed for use in planter boxes, roof gardens and retaining walls.

VersiFlex® offers architects and developers extensive design flexibility and has a wide range of applications in the landscape, building and construction industries.

VersiFlex® modules are 30 mm high and are easy to install, by interlocking in the same plane or by butting together without interlocking.

VersiFlex® can create a thermal insulation barrier.

VersiFlex® has a narrow-profile, open surface design and high internal void volume enabling the rapid capture and transport of high water volumes.

VersiFlex® stackable and nestable design halves on-site storage space requirements and transportation costs compared to competitive products.


VersiFlex® flexible drainage modules effectively drain water on:

  • Planter boxes
  • Roof gardens
  • Landscaped decks
  • Retaining/basement walls

VersiFlex® efficiently drains water in planter boxes and on roof garden and landscaped deck applications.

  • High compressive strength of approximately 70t/m²
  • High surface void area and internal void volume resulting in efficient water capture and discharge rates
  • Modules that may be interlocked in one plane or butted together
  • Resistance to biological attack and to a wide range of soil-borne chemicals
  • Stackable and nestable design halves on-site storage space requirements and transportation costs compared to competitive products

VersiFlex® modules interlock or maybe butted together without interlocking

VersiFlex® is flexible and conforms to uneven and curved surfaces

  • Lightweight modules that allow easy handling and installation
  • Approximately 2% of gravel aggregate weight for the same discharge capacity
  • More predictable drainage capacity than gravel
  • Narrow profile enables a greater soil depth to be utilised in planter beds, compared to gravel, allowing the use of a wider variety of landscape plants
  • Relief of hydrostatic pressure on retaining walls
  • Application on curved and irregular surfaces

VersiFlex® provides efficient drainage even on curved and irregular shaped basement and retaining walls

Large pre-assembled VersiFlex® panels are lightweight and easily installed in planter boxes and on landscaped deck areas.
