What is permeable block paving and how does it work?
Permeable paving is an intelligent approach to rainwater management around the home. Whilst retaining the well respected aesthetics, utility and durability of concrete block paving, permeable block paving reduces the volume of surface water run off, slows down the rate at which rainwater enters the drainage system and will ultimately reduce flooding and pollution.
Permeable block paving has a dual role:
PROVIDING A HARD SURFACE FOR TRAFFICKING
PROVIDING THE DRAINAGE SYSTEM AS PERMEABLE PAVING ALLOWS RAINWATER TO FILTER THROUGH THE GAPS BETWEEN THE BLOCKS
Permeable Block Paving is availablein exactly the same comprehensive range of colours and styles:
The deeper, open-graded stone sub-base on which the blocks are laid has sufficient reservoir space to store the rainwater underground preventing rapid surface water run off. The stored water may gradually soak into the ground, be collected for irrigation or harvested for re-use around the home for car washing or even toilet flushing.

This is an example of the Total Infiltration System. This ‘Zero Drainage’ system requires no discharge into traditional drainage systems, removing the need for pipes and gulleys resulting in cost savings.
This is just one of the many different ways to deal with rain water run off including soakaways, gravel ditches and rainwater gardens. To disscuss the most suitable option for your needs contact Driveways By Design now and talk to our experts.
