Xflo Rectangular Permeable Paving


Suitable for all pavements from light duty pedestrian to heavy duty traffic.


A range of permeable paving blocks designed to provide a 'source control' sustainable urban drainage system (SuDS) in combination with a sub-base specification.

Surface water flows through the joints and is absorbed into the underlying voided sub-base where the water is treated, stored and slowly released into the ground (infiltration) or the surface water drainage system (attenuation).

Features and benefits:

  • Designed to allow an initial surface infiltration in the order of 2000 L/s/ha.
  • Manufactured from locally sourced high grade aggregates with a fine textured finish to give a distinctive colour.
  • The standard 200 x 100 mm module size and colour range are compatible with rectangular paving.
  • The enlarged spacers on the sides of the block create 6 mm wide joints which allow surface water to pass through the paving.
