Porous, fast draining car park surface for college campus

This large college needed to increase parking capacity for students and staff and commissioned a new 5,500m2 car park. Local planning guidelines encouraged a sustainable approach to drainage to avoid excessive run-off into the local catchment. It would be used throughout the year, so there was also a requirement to avoid standing water during heavy rain. As it would be in frequent use by large numbers of staff and students, the chosen surfacing needed to provide long term durability with minimal maintenance requirement.

After discussions with the main contractor, Tarmac’s experienced team recommended ULTIPOROUS, their specialist porous asphalt car park surface. Using a modified binder and open aggregate structure, ULTIPOROUS combines excellent drainage characteristics with long term durability. It reduces direct surface water run-off to help meet planning requirements. It also eliminates the problem of both standing water after heavy rain and ice patches that can occur in cold weather conditions.
