Description

Permeblox is a versatile, robust, high performing rigid drainage board.


Manufactured from 100% recycled materials, the component ingredients have been heat bonded together in a unique patented process to create a drainage board with high flow characteristics on a macro level and storm water retention properties on a micro level.


The board can be installed over a variety of surfaces and overlaid with several construction materials and finishes. It has a high compressive strength, suitable for being used in load bearing areas with the correct design application.


Features and benefits:

  • The product has a high compressive strength suitable for use in load bearing areas with correct design application.
  • High environmental credentials and delivers direct Co2 (carbon negative) savings to all projects in use.
  • Manufactured using 100% post-use (end of life) recycled feedstock.
  • Can be continuously recycled by the manufacturer.
  • Can be trafficked during construction.
  • Can be installed over flat, pitched or vertical surfaces and overlaid with a wide range of construction materials and finishes.
  • Unsupported push through force 8997 N (0.917 tons over 200 mm unsupported span).
