When we install a driveway, drainage is one of the first things we look at. A standard impermeable surface, such as solid tarmac, concrete, or porcelain slabs laid on a full bed, pushes rainwater sideways. If that water runs onto the public highway, you may need planning permission before the work can go ahead.
We use permeable driveway systems to help avoid that issue wherever possible. Resin-bound and gravel surfaces allow water to drain through the material, while permeable block paving directs water through the joints and into the prepared sub-base below. When water stays within your property instead of running onto the road, planning permission is not usually required for most front garden driveways.
This is where SUDS, or Sustainable Drainage Systems, matters. We install permeable surfaces that help reduce surface water entering local drains during heavy rain, which is increasingly important for many Kent properties.
Three Permeable Options We Install
Resin-bound driveways
We mix natural aggregates with clear resin on-site, then hand-lay the material in a seamless layer over a prepared base. This creates a smooth, hard-wearing surface with no loose stones. Water drains through the surface naturally.
Curing time is usually around 4 to 6 hours, with foot traffic possible within 24 hours and vehicles within 48 hours. With the right base preparation and occasional maintenance, a well-laid resin-bound driveway can last 15–25 years. We also discuss colour and aggregate options during the free site survey.
Gravel driveways
We install gravel driveways as a naturally permeable and cost-effective option.We excavate to the correct depth, lay a suitable compacted sub-base for the site, install a heavy-duty breathable membrane to help limit weed growth while preserving drainage, and finish with angular decorative aggregate at 40–50mm depth.
We use angular gravel because it locks together better than rounded stone and helps reduce scatter under tyres. The finished surface remains naturally porous, with no additional drainage engineering needed for most front gardens.
Permeable block paving
We install permeable block paving by specifying the joint spacing and drainage bed correctly from the start. We excavate to the required depth, lay a suitable open-graded permeable sub-base, then bed and lay the blocks with permeable jointing or infill to allow water to drain down into the base below.
We can create the same visual styles as standard block paving, including herringbone, basketweave, linear, and custom layouts. We also like this option because individual blocks can be replaced later if one shifts or stains.
