The RootRain Hydrogrille tree aeration system maintains long term soil health and fertility by facilitating high volumes of water and oxygen to reach the tree rooting area directly and allowing toxic gasses to escape – a critical tree welfare factor especially in the first few years of its life in a new tree pit. Soil under paved areas without a RootRain system will quickly become anaerobic due to lack of water and oxygen, this will result in tree mortality.

The Hydrogrille twist locks into GBU’s high-quality range of Ductile Iron Tree Surrounds for security and stability. The lift and swing lid is intended for easy access for cleaning and has the capacity to withstand heavy vehicular overrun, including from street sweepers in hardscape areas.
