Tarmac Laying Contractor in Trevescan

Tarmac Laying Contractors in Trevescan — what to expect

In Trevescan, as in much of West Cornwall, the combination of coastal weather and heavy farm traffic means that a well-constructed tarmac driveway, path, or private road is less of a luxury and more of a practical necessity. Local groundworkers typically begin with a firm sub-base of MOT Type 1 limestone, laid and levelled before being compacted with a vibrating plate or, for wider runs, a proper roller. From there, the standard approach is a two-layer system: a robust AC 20 binder course to take the structural load, followed by an AC 10 surface course for a smooth, dense finish. For existing but failing surfaces, a plane and overlay is often the more cost-effective route, provided the old base is sound; this involves milling off the top few centimetres, applying a tack coat to ensure the new layers bond, and re-laying fresh tarmac without disturbing the underlying ground. Edge restraint kerbs or haunching are usually set first to define the shape and keep the material locked in place, and any driveway drainage is considered early on to avoid standing water. Many Trevescan properties also require dropped kerbs where the drive meets the public highway, which involves a separate council application and a careful dig-down to the correct depth. For a lighter, more rural finish, some prefer a tar and chip dressing over a binder course, though full tarmac laying remains the most common choice for longevity. If you’re planning such work in the TR19 area, it is worth speaking to two or three local contractors to compare quotes and get a feel for their proposed method statements.
