Permeable block paving in Carmarthen: the local picture
In and around Carmarthen, village-style frontages sit alongside newer cul-de-sacs, so the right block often depends on the age of the house.
Wales is wetter than most of England, and new front paving has to be permeable or drain within the property, so drainage is designed in from the start.

What you get with our permeable paving service
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
- Open-graded crushed stone (no fines) laid and compacted in layers
- Edge restraints and any overflow or outlet the design needs
- Ground check: how well the soil drains and how high the water table sits
- Geotextile layer where the design needs one
Before we price your permeable block drive
- Access for a mini-digger, skip or grab lorry
- Levels against the damp-proof course (the finished paving must sit at least 150 mm below it)
- Block range, thickness, colour and pattern to suit the house
- Where an electric vehicle charger cable might run
- The kerb: is it already dropped, and is it wide enough?
Planning and kerb rules in Carmarthen
Carmarthen 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.
