Strata Cell modules interlock to form an effective root management system for protecting and limiting damage to city pavements.
Pavements need to be engineered to endure static and cyclic vertical loads in accordance with relevant city planning laws.
Emergency vehicles need to access properties without causing disastrous destruction of the pavement. Tree pits must provide large amounts of uncompacted soil for root growth while supporting applied vertical loads.
Strata Cell modules from Arborgreen Landscape Products have been designed to support huge vertical loads, bringing tree roots closer to the surface. Tests have revealed an assembled Strata Cell matrix root management system can withstand up to 550kPa vertical load.
Strata Cell matrixes can support maximum traffic loads with only 300mm of granular pavement depth according to engineer calculations. Poured concrete slabs and lighter traffic loads may allow for the Strata Cell root management system matrix to be closer to the surface.
Apart from direct lateral loads, tree pits can feel the stress of significant lateral force, particularly tree pits behind kerbs and gutters. Repeated strain through heavy traffic can cause the base course to displace laterally into the tree pit void space and deteriorate road pavement adjacent to the tree pit.
Engineered space for tree root systems must be capable of withstanding this lateral force.
Strata Cell root management system units lock together to form a monolithic structure with excellent modular strength, both vertically and laterally.
The Strata Cell matrix provides an optimal growth zone for tree roots with it’s open, skeletal structure, in excess of 94% of the total volume is available for root growth.
These high soil-volume tree pits are more beneficial to trees as they make provision for the laws of nature.
