ENVIRA is an innovative concrete pervious to water.
It offers high added value to the construction of outdoor pavings, such as car parks,
as it allows rainwater to flow into the substrate.
This reduces the cost of building and maintaining drainage systems
to handle storm runoff and significantly helps to protect the environment
