The Tree Outlines mark the growth location and form a neat yet solid edge to delineate and complete the street paving. These Outlines can be incorporated into street paving in one of several ways, e.g. flush or raised to hold back water containing gritting salt. It is possible to include groundspots in combination with the Tree Air® system. Various diameters can be produced on request. Available in unfinished carbon steel or thermogalvanised steel (powder coating on request). Streetlife can offer bespoke solutions and is happy to advise you in this respect.
