200L x 100W x 80D mm 50 units per m2
Quite possibly the hardest working paver in the world, as it does its best work in the pouring rain!
Firth FlowPave is part of the Firth EcoPave® Permeable Paving Range, which helps manage stormwater peak flows, and improves water quality by filtering harmful pollutants, helping to keep our waterways clean and healthy. Flowpave 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. Easy to maintain, simply sweep the surface of the paver as required.

EcoPave® Permeable Paving Benefits
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 stormwater 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)
