In this article, Vuba explores how resin bound surfacing and permeable base solutions can help local authorities manage surface water, improve accessibility and minimise disruption when delivering public realm and active travel schemes.
The article looks at the potential benefits of VubaMac and how these solutions can support the development of more sustainable, accessible public spaces.
Managing surface water, improving accessibility and reducing disruption are key considerations when local authorities specify public realm and active travel infrastructure. Resin bound surfacing, combined with a suitable permeable base, offers an option for footways, cycle routes, parks and community spaces.
Supporting surface water management
Resin bound surfacing combines natural aggregates with specialist resin to create a continuous, porous surface. Rainwater can pass through the finish into the underlying construction, supporting Sustainable Drainage Systems (SuDS) when the complete pavement and drainage arrangements are appropriately designed.
Vuba reports that testing by the University of Hull’s Flood Innovation Centre demonstrated permeability 19 times greater than block paving, with zero surface water runoff recorded under the test conditions. Vuba also publishes a drainage rate of approximately 2,200 litres per square metre per minute for its VubaMac system.
For local authority schemes, these results demonstrate drainage potential rather than a guaranteed site infiltration rate. Ground conditions, sub-base capacity, outfalls and ongoing maintenance remain essential parts of the design.
An alternative to conventional bases
VubaMac is a permeable binder course developed for use beneath resin bound surfacing, offering an alternative to asphalt or concrete bases. The system incorporates structural reinforcement mesh and bonds with the resin bound finish to form an integrated construction.
The finish can be installed on the same day as VubaMac, subject to conditions and application requirements. This can simplify sequencing and reduce the interval between base construction and completion useful where pedestrian access, neighbouring businesses or community facilities need to be considered.
Reducing excavation and disturbance
VubaMac can support reduced-dig construction and, where the project-specific design permits, no-dig solutions. Reducing excavation can mean less spoil to remove, fewer material movements and less disruption around the works.
These approaches may be particularly relevant to park paths and routes near established trees. Within root protection areas, the build-up must be agreed with the project engineer and arboriculturist, including any required cellular confinement or tree-protection system.
Specifying for public use
A continuous finish without loose aggregate can support the design of accessible routes, while colour choices allow surfaces to respond to their surroundings and distinguish different spaces.
For local authorities reviewing surfacing options, resin bound and VubaMac provide an additional approach to consider within the wider design of durable, accessible and water-sensitive public spaces.
