Pre-formed geocellular sub-base replacement unit attention/ infiltration system. The ArborRaft System creates an artificial forest floor which prevents soil compaction and protects the hard landscape. It creates an air void which diverts root growth away from the surface. It works with the tree’s roots to guarantee delivery of essential water and nutrients yet also encouraging root growth that mirrors the tree’s canopy.
