Porous Lane & Glen Eira Council

Porous Lane is the new standard in permeable paving developed through extensive research at the University of Melbourne. What sets it apart is its exceptional permeability, achieving infiltration rates 8 to 10 times higher than industry benchmarks, dramatically reducing runoff, and offering a powerful tool for urban flood mitigation.

Its innovative composition incorporates up to 60% local NZ recycled tyre rubber, transforming a major waste stream into high-performance infrastructure. Unlike traditional permeable surfaces, Porous Lane delivers enhanced durability and flexibility.

It’s a safer, lower-maintenance, and more reliable option when selecting permeable surface. Porous Lane proves that infrastructure can be circular, sustainable and resilient. It’s a smart stormwater solution tailor made in and for Aotearoa.
