Tarmac Laying Contractors in Kennington — what to expect

For homeowners across Kennington and the surrounding TN24 district, having a new tarmac driveway laid or an existing one refreshed is a job that calls for proper ground preparation and the right materials, and local contractors in Kent are well used to the clay-heavy soils that can shift if a sub-base is skimped on. A typical installation will start with excavating to the correct depth, then bringing in MOT Type 1 sub-base, which is spread and compacted in layers using a vibrating plate or a roller for larger areas, before any binder goes down. From there, an AC 20 binder course is laid to give the structure its strength, followed by an AC 10 surface course for that smooth, dark finish that drains well and stands up to our wet winters. For paths and private road surfacing, the same principles apply, though edge restraint kerbs are often set in concrete to keep the edges crisp and prevent the tarmac from feathering. If your existing driveway has sunk or cracked but the base is still sound, a plane and overlay can save time and money, though it’s worth checking the height against your damp-proof course and dropped kerbs. A tack coat is sprayed on before the new layer to ensure the old and new tarmac bond properly, and while tar and chip is a cheaper option for farm tracks, most Kennington residents prefer a clean tarmac finish. The key is getting the drainage right, especially near the pavement, so water doesn’t pool or run onto the road. It pays to have a look at a few local quotes to see what feels right for your project.
