from the most damaging roads. On any trafficked surface, concrete block permeable paving offers a real opportunity to address this major problem by trapping vehicle pollution.
Permeable paving can provide a completely level, well-drained, firm and slip-resistant surface accessible to all, without the need for cross-falls, channels, gulleys or other interruptions. Rainwater ‘ponding’ is eliminated, reducing the risk of ice forming on the surface and preventing splashing from standing water.
But it also allows water to reach tree and shrub roots, despite providing a hard surface above: in fact, the Code of Practice for accessibility in the external environment, BS 8300-1:2018, calls for permeable paving instead of tree grilles. And it can also help reduce ‘urban heat island’ effects, i.e. evaporation of rainwater within the paving. This is in addition to the high albedo – or heat reflectance – offered by modular concrete paving.
Retrofitted permeable paving Bringing these issues together, an award- winning, exemplary SuDS scheme near Australia Road, London, demonstrates the

multifunctional benefits of retrofitting permeable paving in place of conventional surfaces. Its design, by Robert Bray Associates, introduces the concept of concrete block permeable paving as a thin overlay to existing streets, removing rainwater straight from the surface without gullies and providing some water attenuation and treatment before discharging to adjacent, well-planted SuDS basins. This innovative concept opens up wider possibilities for all hard surfaces. Modular concrete paving offers designers the potential to create safe, attractive and comfortable urban spaces for the post- pandemic environment, with maximum flexibility to meet future challenges and minimal interventions with retrofit, while reducing flooding, pollution and urban heating.
Chris Hodson is a consultant to Interpave Paving gone for a Burton? Not with Resiblock!
Following the successful use of Resiblock at the world-famous FA Academy at St Georges Park, Staffordshire Borough Council did not have to look far for the solution of sealing Station Street, Burton. The Station Street Project saw the
installation of a mixture of new textured concrete block and slab paving to help define pedestrianised spaces from delivery vehicle routes. Resiblock and the ‘22’ A.F product ensured Asset Protection by matching the key client request of providing a sustainable solution which would ensure low future maintenance costs.
mail@resiblock.com Weatherproof your paving
As temperatures get lower, puddles and ponded water freeze, having the potential to not only damage your paving but also poses a serious risk of falling and injury. Weatherproof your paving and stay safe this winter with permeable paving
solutions from UltraScape. UltraScape perma-bed bedding mortar has been specifically designed with permeability in mind. This innovative bedding mortar is proven to reduce water related pavement failures as any rainwater will drain away naturally, rather than sit on top of the stone, or worse, stay within the joint, freeze, expand and then break out – allowing you to enjoy your paving for years to come.
