Block paving sealing in Dartford: the local picture
Dartford is a sizeable town with a mix of semis, terraces and newer estates, and many drives here were first laid decades ago.
Chalk, clay and sandy ground all occur across the South East, so the dig and sub-base depth are set on the survey rather than assumed.

What you get with our sealing service
Sealing block paving means applying a clear liquid sealer to clean, dry paving. A good sealer soaks into the blocks and the jointing sand, binding the sand so it does not wash out, reducing staining and making the surface easier to keep clean. Some sealers also deepen the colour or leave a light sheen.
