Permeable Paving & SuDS

An essential introductory guide to all aspects of permeable paving for designers, developers, planners, regulators and all those involved with development. This edition reflects the latest thinking based on experience from long-term usage and reviews recent innovations and developments.

Concrete block permeable paving provides ‘Cool Pavements’, helping to reduce the urban heat island effect, with evaporation of rainwater from the surface and within the paving. This enhances the high albedo – or heat reflectance – offered by concrete block or flag paving generally, compared with asphalt.

Multifunctional Sustainable Drainage

Concrete Block Permeable Paving is an essential sustainable drainage (SuDS) technique. It simply allows water to pass through joint filling material in gaps between concrete paving blocks or flags into the underlying permeable sub-base. Here, it is stored and released gradually to help prevent flooding. At the same time, many pollutants are substantially removed and treated within the pavement itself.

Key benefits include:

  • Reducing, attenuating and treating runoff near the surface
  • Direct infiltration or conveyance to the management train
  • Multi-functional SuDS meeting current guidelines
  • Established technology with proven performance
  • No additional land-take and lower whole-life costs
  • Safe, level, puddle-free, shared surfaces for all
  • A gradual supply of clean water for landscape, biodiversity and harvesting
