Permeable concrete

Hydromedia is a water management system that rapidly absorbs rain water off streets, parking surfaces, driveways and walkways – reducing the risk of flooding. This permeable solution combines the properties of concrete and advanced drainage technology. 

Water is the world’s most vital resource and requires proper management in order to reap its benefits while avoiding its adverse effects. Hydromedia enables the ultra-rapid evacuation of water directly into the soil. This produces a natural aquifer recharge or enables the water to be recycled. The Hydromedia range is designed to cover all your possible needs, from street pavements to roofing solutions.

Hydromedia in action

Hydromedia used in Europe’s largest urban regeneration project

Hydromedia permeable concrete is being used in the Ellinikon – an urban regeneration project located outside Athens, Greece. Hydromedia will enable smart rain water management for the site that will be home to residential, office and retail buildings.

Drainage solution for a major tunnel in Croatia

The drainage channel of one of the Istrian Y motorway’s key tunnels was built using Hydromedia. Holcim provided an integrated solution for the tunnel to lower the project’s carbon footprint and improve the tunnel’s drainage during times of heavy rainfall.
