Trees are perhaps more valued in an urban landscape than in any other. However there can be a tension, their growth can disturb paving and there is often a requirement to plant them into areas that are heavily trafficked.
A solution to the needs of clients for a clean integrated surface and the requirements of the tree, is a suitably specified ‘tree pit’ surface.
There are several options available to the landscape architect or planner these are dependent on cost and design criteria. They include porous resin bound aggregates and more flexible rubber systems. The advantage for newly planted trees is that when properly installed resin systems are durable and virtually maintenance free.
Other tree surrounds and tree pit bases use self-binding gravels, although less clean that the resin bound materials these may be easier to install when applying to large exiting tree stock.
