Every year, many properties and millions of dollars worth of assets are destroyed from rising rivers backflowing into suburban stormwater systems.
This is preventable with a backflow prevention device. Polynex manufactures a range of HDPE flood flap gates, which can be fitted to stormwater outlets flowing into rivers or the ocean.
The backflow device can be customised to be rectangular or circular, large or small, and a full elastomer seal is available if required.
Maintenance-free durability is at the core of design; the HDPE material gives the flap gate the toughness and integrity demanded from the harshest of conditions.
