What to know before a replacement block drive in Dartford
In Dartford, many front gardens have already been paved once, so new paving often starts with breaking out the old surface.
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 does a replacement block drive involve?
Sometimes the old base can be kept: a thick, sound concrete or well-compacted hardcore layer may only need trimming and topping up. Often it cannot, because it was too thin, has sunk or sits too high against the house. The survey checks levels against the damp-proof course and the existing base before the quote is written, so the price reflects the real dig.
- Levels set below the damp-proof course with falls away from the house
- New edging, sub-base where needed, and the block drive
- Drainage added where the old drive sent water to the house or road
- Assessment of the old base: keep, top up or replace
- Break-out of the old surface with waste removal and skip or grab lorry
What the survey covers
- The kerb: is it already dropped, and is it wide enough?
- Ground conditions under the old surface and how deep the sub-base must be
- Steps, thresholds and door heights
- Where an electric vehicle charger cable might run
- Access for a mini-digger, skip or grab lorry
Rules for front drives in Dartford
Dartford is in England, so these rules apply:
In England, paving in front of the house that covers more than 5 m² needs planning permission unless it is permeable or drains to a lawn, border or soakaway inside your boundary. Permeable block paving, or standard blocks laid to fall onto a planted strip, avoid the need for permission in most cases.
Flats and maisonettes, listed buildings, and homes covered by an Article 4 direction can have tighter rules, and conservation areas, National Parks and National Landscapes restrict some permitted development.
A dropped kerb needs your local highway authority's approval (usually the county, unitary, metropolitan or London borough council), and a new access onto an A, B or C classified road also needs planning permission.
General guidance, not legal advice. Your survey confirms what applies to your home. See the planning guide.
