Client: RC Taylor Location: Crouch, Kent Product: Bodcell™ 220/200 Tree root protection Application: Vehicle access road over tree roots
The Problem: The access route to a new housing development required the construction of a roadway which crossed over an area where tree roots were close and at surface level. In order not to damage the roots, Bodcell™ was specified with the dual purpose of offering a strong stable base for the access routes whilst protecting tree roots from damage. The Solution: Boddingtons’ Bodcell™ cellular confinement system was used as it offered the perfect solution for tree root protection where a road of driveway is required whilst preventing soil compaction and protecting tree roots. Bodcell™ cellular confinement system ensured that downward forces by vehicles are spread laterally reducing loads on the underlying soils. Without the cellular system, the surface would have become compacted and rutted with the forces pushing downwards damaging the tree roots and possibly killing the trees.
Bodcell™ was installed onto the level surface on top of a geotextile. The cells were filled with a type 1 roadstone and compacted flat A geotextile and binding layer were installed on top of the cells and the surface finished with small angular gravel.
Conclusion: The permeable cells allowed natural drainage and stopped compaction from vehicle tyres. The cells confined the stone fill ensuring that any downward forces were spread laterally. Bodcell™ ensured that the access road caused no damage to the tree roots.
