Tar and chip for private roads, shared drives and estate roads
Short answer: tar and chip is one of the most practical surfaces for a private road, a shared drive or a residents' access road. It is the same basic method councils use to resurface country lanes, it costs far less per square metre than resin or block paving over a large area, and a long road can be done in sections.
Who looks after a private road?
If a road has not been adopted by the highway authority (Hampshire County Council, Surrey County Council or West Sussex County Council across most of the area we cover), the council does not maintain it. Responsibility usually sits with the owners of the road or of the properties along it, often through a residents' association or a management company. The title deeds or the transfer for each property often set out who pays what, so they are the place to start if you are not sure.
Why tar and chip suits longer roads
- Cost over a large area: on a road that is 100 metres or more long, the difference per square metre between tar and chip and other surfaces adds up quickly.
- Grip: the chipped texture gives good traction for cars, delivery vans and people on foot, including on slopes and in the wet.
- Looks right in the country: a golden or natural stone chip sits well alongside hedges, verges and older buildings. See colours and finishes.
- Can go over an existing surface: if an old tarmac road is sound but worn, a new dressing can often be laid on top. See tar and chip over an existing driveway.
Surface dressing for management companies
For an estate road or shared access that is structurally sound but tired, a surface dressing is often the most cost-effective option. The existing surface is cleaned, potholes and broken edges are repaired, then a new layer of binder and chippings is laid. It seals the surface against water, which is what breaks roads up over winter. Doing the repairs and the dressing as one planned job, rather than patching potholes one at a time, usually gives a better result for the money.
What to sort out before work starts
- Agreement from everyone who shares the road, including how the cost is split and when access will be restricted.
- Drainage: water standing on a road or running down it is the main cause of failure, so falls, gullies and soakaways should be checked as part of the quote.
- Access during the work: doing the road in sections lets residents still get in and out.
- Timing: the binder needs warm, dry weather. See the best time of year.
What does it cost?
Most tar and chip work falls between about £15 and £30 per square metre, depending on the condition of the existing base and how much preparation is needed. A large, sound road tends to sit towards the lower end; one that needs a new sub-base costs more. See the full cost guide.
