When comparing resin driveway vs tarmac, the main differences come down to appearance, drainage, and long-term maintenance.
Resin driveways offer a much more refined finish. They are available in a range of natural stone colours and create a smooth, seamless surface. Tarmac, by comparison, has a more basic look and is usually limited to a dark, uniform finish.
From a drainage perspective, resin bound surfaces are permeable, meaning water drains through the surface. Tarmac is not permeable, so water runs off and requires proper drainage planning.
In terms of maintenance, tarmac can soften in hot weather and may develop marks or depressions over time, especially where vehicles are parked regularly. Resin surfaces, when installed correctly, tend to hold their shape better and require less ongoing repair.
