What to know before a permeable block drive in Cwmbran
Cwmbran is a sizeable town with a mix of semis, terraces and newer estates, and many drives here were first laid decades ago.
Hilly streets in much of Wales mean many drives slope, which shapes the falls, the edging and the water route.

What is included?
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.
- Grit laying course and permeable blocks with grit-filled joints
- Edge restraints and any overflow or outlet the design needs
- Ground check: how well the soil drains and how high the water table sits
- Open-graded crushed stone (no fines) laid and compacted in layers
- Geotextile layer where the design needs one
What we check on a Cwmbran survey
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
- The kerb: is it already dropped, and is it wide enough?
- Where an electric vehicle charger cable might run
- Ground conditions under the old surface and how deep the sub-base must be
- Edges against lawns, beds, walls and neighbours
Planning and kerb rules in Cwmbran
Cwmbran 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.
