Aquaflow Permeable Paving and Stormwater Source Control System. All of the Aquaflow blocks and slabs provide drainage through vertical channels and will allow water through the surface at a rate of approximately 9000mm per hour (9000 litres per m2 per hour). Aquaflow paving system delivers immediate environmental benefits and financial savings, when compared to traditional drainage. The system can also be used to harvest and reuse all water that falls on hard surfaces such as roofs and car parks, representing additional environmental benefits and cost savings.

Over the past 15 years the ‘Hanson Formpave Aquaflow’ system has become the Flagship design for permeable paving. The unique sub-base cleans pollutants from run-off, creating a safe, PH neutral water for storage and re-use within the sub-base. Water can be captured from all impermeable areas; roofs, paths and driveways.

It can be further stored in a tank and then pumped out for all exterior uses; gardens and car washing. Inca Concrete Products hold the block design and methodology rights to Aquaflow Permeable Paving and Sustainable Urban Drainage Systems (SUDS) in the Western Cape.Hanson’s Formpave offer is an affordable solution to the challenges of storm water disposal and treatment and water conservation, re cycling and reuse. The entire Aquaflow Range can be made from special aggregates , and with special colours surface finishes all to special order.
