Hydromedia TM
Sustainable
urban drainage
Hydromedia is is a new fast draining
concrete pavement solution that
rapidly directs stormwater from off streets,
parking surfaces, driveways and
walkways. A cutting-edge development,
Hydromedia also minimizes minimises the cost
and long-term maintenance for local
authorities and developers of stormwater
management.
Its advanced, engineered design offers not only
best-in-class drainage and a surface resilient to wear
but also an industry-leading aesthetic appeal and
an increased ease of placement by contractors.
The key to this improved performance is an innovative
mix design developed by Lafarge’s world-class R&D
labs. Outperforming the benchmarks set by standard
permeable pavements, Hydromedia is a sustainable
solution that combines the durability of concrete with
advanced drainage technology.
