Water Permeable Concrete
Hydromedia is an ideal solution for surface water and stormwater management. This fast-draining concrete pavement channels runoff from streets, car parks, driveways and walkways into the ground, reducing ponding and flood risk.
With an engineered sub-base and interconnected void structure, Hydromedia promotes natural aquifer recharge or can be configured for on-site capture and reuse. By reducing reliance on conventional drainage, it can lower whole-of-life stormwater costs and maintenance for councils and developers.
Beyond effective water management, Hydromedia contributes to creating safer, more resilient urban environments. Its advanced porous composition allows rainfall to pass directly through the pavement, reducing surface runoff and the strain on traditional stormwater systems. This helps prevent flooding during heavy rain events and supports healthier ecosystems by replenishing groundwater and mitigating soil sealing. Hydromedia’s innovative design demonstrates how performance and sustainability can work together.
Hydromedia permeable concrete rapidly absorbs rainwater from streets, parking surfaces, driveways, and walkways - thus reducing the risk of flooding.
Key Benefits
Hydromedia brings nature into cities and helps cool urban spaces. In Aubervilliers, France, Holcim’s permeable concrete enabled Fieldwork Architecture to create a green public space where trees thrive through natural rainwater infiltration.
