New Thirsty Asphalt Soaks Up 4,000L Of Water In Minute

Topmix Permeable is a fast draining concrete pavement solution that rapidly directs stormwater off streets, parking surfaces, driveways and walkways. This minimises the cost and long-term maintenance for local authorities and developers of stormwater management.via: Tarmac

This solution provided a number of benefits to this project. It was installed by Tarmac’s Construction Solutions team meaning that expertise was on site to ensure the installation was successful.This new type of porous concrete can absorb up to 4,000 litres of water in minute.

Trafficking could take place within 7 days of application and the permeability rate is considerably higher than alternative permeable pavement solutions.


The project is substantially complete, with one phase remaining and has delivered on schedule, on budget and to the agreed design specification. Already, despite recent heavy seasonal rainfall the pavement has proven to be free-draining, staying dry and is delivering the water attenuation required by the designer.
