CU Structural Tree Soil’s composition is a mixture of gap-graded crushed stone, clay loam and a hydrogel stabilizing agent which keeps the mixture from separating. It provides an integrated, root penetrable, high strength pavement system that shifts design away from unsustainable individual tree pits which are known to create long term damage to surface pavement systems through root heave which leave the tree under nourished and consequently reduces the urban trees lifespan.
CU Structural Tree Soil is an ideal combination of structural fill and tree rootzone material for use in urban greening construction projects. It is also more environmentally friendly compared to the other products on the market. CU Structural Tree Soil is 100% recyclable and uses natural materials in its construction, it will not deteriorate over time and it is the most financially competitive solution on the market.
CU Structural Tree Soil has a very important secondary application where it can be installed as a dual function option, to provide a healthy, load-bearing rooting medium for urban tree planting, as well as a rainwater attenuation system to help comply with SuDS obligations for an urban development project.
