Planning a block paving sealing job in Carmarthen
Carmarthen is a smaller town, and many of its homes have more frontage to work with than city houses, which leaves room for borders and planting.
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 sealing service
Sealing only works on paving that has been cleaned and re-sanded first and is completely dry, so it is usually part of a clean, re-sand and seal package. It is not permanent: most sealers need renewing every three to seven years as they wear in the wheel tracks, and new paving should be left for a few months before sealing so moisture and any white efflorescence can clear.
- Edges, walls and doors protected
- Drying time and a date when cars can return
- Check that the paving is clean, re-sanded and dry
- Second coat where the product requires it
- Sealer applied evenly by roller or low-pressure sprayer
