What does a permeable block drive involve?
Permeable block paving is block paving built so that rainwater drains down through the joints into a deep, open-graded stone sub-base, where it is stored and soaks away slowly into the ground or is piped off. The blocks have small spacers or wider joints filled with fine grit instead of sand.
- Geotextile layer where the design needs one
- Edge restraints and any overflow or outlet the design needs
- Ground check: how well the soil drains and how high the water table sits
- Grit laying course and permeable blocks with grit-filled joints
- Deeper dig-out for the open-graded sub-base
What we check on a Barry survey
- Existing manhole and inspection covers, and whether to recess them
- Trees and roots near the drive
- Steps, thresholds and door heights
- Block range, thickness, colour and pattern to suit the house
- The kerb: is it already dropped, and is it wide enough?
Rules for front drives in Barry
Barry is in Wales, so these rules apply:
In Wales, any new or replacement hard surface at the front of a house should be permeable or drain to a permeable area within the property to avoid needing planning permission. Unlike England, there is no 5 m² allowance for new paving; only repairs of up to 5 m² of existing surface are exempt.
Since January 2019, construction work covering 100 m² or more with drainage implications, including drives and patios, needs approval from the local SuDS Approving Body (SAB) before work starts, even where planning permission is not needed.
A dropped kerb needs your council's approval as highway authority, and a new access onto a classified road needs planning permission.
General guidance, not legal advice. Your survey confirms what applies to your home. See the planning guide.
