Fortress Tree Grille

Product Code: 170UR3220-pro

The gt Fortress Tree Grille is a stylish and practical tree grille with the urban setting in mind. The design allows paving to be continued almost up to the tree trunk, protecting the trees root system from urban traffic and soil compaction but also allowing rainwater through to maximise irrigation and urban drainage. To ensure the maintenance of the tree, a Mona Irrigation Unit can be fitted seamlessly into the grille and paving scheme. As a standard item, the gt Fortress Tree Grille is ideal for use with block paving, but dimensions of the inner trays can be altered to suit other paving styles. As with all gt tree grilles, the inner trays or grille sections are fastened with security fixings and are fully removable allowing the tree to be removed and replaced if required.

Fixing and installation

  • The two halves of the outer frame are bolted together and fixed directly to a level concrete pad foundation around the tree pit. To avoid trip-hazard set pad foundation so that grille is flush with finished paving level (ragged legs can be added if required).
  • The inner trays can then be installed and fastened into place using the fixing fillets, through-fixed to a captive nut in the outer frame braces.
  • These fillets can then be used as lifting brackets if the inner tray needs removing at a later date.
  • Outer frame can be supplied toe in or toe out depending on site needs, although toe out is a better structural unit.
