Quite possibly the hardest working paver in the world, as it does it's best work in the pouring rain!
Firth FlowPave is one of the paver options in the Firth EcoPave™ System. The paver has enlarged nibs on all four sides which creates wider than usual gaps around each paver. This space allows water to filter through to the underlying drainage medium.
FlowPave is ideal for light to medium residential traffic areas including car parks. Nib spacers on the paver create wide gaps around paver to allow water drainage.

Reduces rainfall runoff from hard surfaces, decreasing the demand on drainage systems.
Reduces the need for retention structures (e.g. ground sumps, ponds or dams) and maximises land use by retaining water within the Permeable Paving System.
Recharges natural groundwater and aquifers.
Improves hydrological response of storm water peak flow by holding and releasing in a controlled manner.
Filters run off water by removing heavy metals such as zinc and copper through cationic exchange when using greywacke sub base drainage aggregates.
This product is one of the solutions for storm water management in the proposed unitary plan (Auckland only)
