We're the experts when it comes to stormwater.


EcoBloc SMART is the most innovative stormwater detention and retention product available. 

Plastic storage systems have recently become a popular solution for stormwater detention and retention; however, GRAF Australia has been developing, producing and supplying stormwater products for over 20 years. 

Our current stormwater range, EcoBloc SMART is made entirely of recycled plastic, are durable and light, and easy to install. 

GRAF’s EcoBloc range requires very small amounts of space compared with gravel ditches or concrete drainage pipes and offer a large infiltration volume for a low weight. Other benefits of GRAF infiltration modules include their high load capacity and durability; and on the sustainability front, our modular system means we can transport 8 x more tanks per load – cutting emissions from transport.
