Firth's EcoPave system also preserves water quality and permits rainwater to be absorbed by the pavement. The greywacke aggregate sub-base has the ability to filter contaminants such as Zinc and Copper delivering a cleaner water back into the ground or stormwater system.
Advantages of the Firth EcoPave System:
- Reduces rainfall runoff from hard surfaces decreasing demand on drainage systems.
- Reduces the need for retention structures such as ground sumps.
- Recharges natural groundwater and aquifers.
- Improves hydrological management of stormwater peak flow by releasing in a controlled manner.
- Heavy metals such as zinc and copper may be filtered by cationic exchange using greywacke base course drainage aggregates.
