Tarmac Laying Contractors in Chippenham — what to expect

Whether you’re refreshing a tired front garden in Chippenham or laying a new private road on the outskirts towards Corsham, the tarmac work here is all about getting the ground right before anything else. A proper job starts with excavating to a solid depth, then bringing in MOT Type 1 sub-base, which is spread and compacted in layers using a vibrating plate or, for larger areas, a roller, so you don’t get dips appearing a year down the line. For the asphalt itself, local contractors typically run an AC 20 binder course first, followed by an AC 10 surface course, and they’ll always roll it while the material is still warm to lock the aggregate in place. If you already have a sound base but the surface is cracked or uneven, a plane and overlay is a common approach in the SN15 area—they’ll mill off the old top layer, brush down, apply a tack coat to help the new tarmac bond, and then lay fresh asphalt without disturbing the sub-base. Edge restraint kerbs are worth agreeing on before work starts, because they hold the tarmac together and keep the edges clean, and if you’re connecting to the highway, the dropped kerb and any drainage runs need sorting with the council first. Some homeowners prefer a tar and chip finish for a more rustic drive, but for most paths and drives around Wiltshire, a smooth tarmac overlay is still the practical choice. It’s always sensible to have a couple of Chippenham firms look at your ground conditions and quote on the same specification, just so you can compare like for like before committing.
