Our irrigation and ventilation systems take all the difficulties connected to newly planted and mature trees in urban contexts into account


RootRain PRTG (cast aluminium) and PRCG (cast iron) systems offer architects and designers the option of integrating an irrigation and ventilation system in a tree grille itself.

RootRain PRTG/PRCG is designed for installation in a tree grille and includes a locking mechanism, ensuring a solid connection. The cast aluminium or cast iron cap has a “lift-and-turn” opening for easy irrigation. Read more about tree grilles in the chapter ’Protection’ or the special brochure ’MilPlus’.

Advantages of RootRain PRTG/PRCG
