Hydrorock tree pits control and attenuate surface water run off, minimising flood risk in urban environments. Hydrorock solutions can deal with high rainfall events without the need to connect to a sewage or drainage system, instead storing the water locally and releasing as trees require.
Hydrorock natural aquifer block tree pits are designed to suit site conditions, numbers, species and spacings of trees, local rainfall event requirements and many other criteria.
A typical configuration for stand-alone tree pits in an urban but non-vehicular load bearing location is shown below.
3- module array
In the each sub array, three or four BD 340 blocks were used at a depth of 1300mm, arranged to the side of the tree under the existing parking spaces, with a further block directly in front of the tree. The blocks were connected to ensure fast filling of the sub array.
Not only did the system cause minimal disruption during installation but it is also maintenance-free post installation.
Installation is very simple and quick with minimal disruption.
Blocks are pre-wrapped with filter membrane, so the excavation needs to be only as large as the system (no access is required to fit the membrane).
Projects can be undertaken with minimal disruption with sections of the road or paved areas being dealt with sequentially to maintain area usage and further minimise disruption.
The trees are generally located at intervals dictated by parking spaces or other existing infrastructure and the system is installed around these trees to avoid root disturbance. The installation process is relatively simple and often existing paving materials can be re-used post installation.
Where areas are not subject to heavy vehicular traffic, standard-density blocks can be used, but high density blocks are also available for solutions in trafficked areas.
