Tarmac Laying Contractor in Coldharbour

Tarmac Laying Contractors in Coldharbour — what to expect

For homeowners across Coldharbour and the wider GL15 area, getting a new tarmac driveway laid, or having an existing one refreshed, is a job best left to local contractors who understand the Gloucestershire clay and the wear and tear of rural access. A typical full installation begins with excavating the old surface, then bringing in MOT Type 1 sub-base, which is spread and compacted in layers using a wacker plate or, for larger private roads, a proper roller to ensure a stable foundation that won’t sink or shift over time. The main body of the work usually involves an AC 20 binder course, laid to a depth that suits the expected vehicle weight, followed by an AC 10 surface course for that smooth, dark finish. Where a drive is already in reasonable shape but showing its age, many locals opt for a plane and overlay, which simply removes the top few millimetres and lays a fresh surface course on top, often with a tack coat to guarantee a strong bond. Edge restraint kerbs are set before the tarmac goes down to keep the edges crisp, and if you’re thinking of extending your drive onto the pavement, you’ll need to factor in dropped kerbs, which require council approval but are handled by most contractors as part of the job. Drainage is another consideration, with falls built into the surface to channel water away from your property, while a tar and chip finish can add grip on steeper Coldharbour lanes. Rather than rush into any decision, it’s worth taking your time to compare a few quotes from local firms, just to see what feels right for your budget and your particular stretch of tarmac.
