Resin-bound gravel combines natural stone with tough synthetic resins, creating a hard-wearing surface that's perfect for British driveways and paths.

The UV-stable resin, commonly epoxy or polyurethane, bonds well with various stones – from standard gravel to decorative aggregates you'd find at any UK builders' merchant. Most installers use stones sized between 1-3mm and 2-5mm, about the size of a small pea, which gives the best balance of strength and looks. This surface is also highly customizable with different colors and textures to suit your aesthetic preferences. Additionally, selecting the right stones based on their material properties can enhance durability and performance.

The process is straightforward: a two-part resin gets mixed with your chosen stones until every piece is properly coated, rather like mixing cake ingredients. This thorough mixing is crucial – it's what ensures your surface will stay solid and smart-looking through typical British weather. Think of it as making a very tough concrete, but with a much more attractive finish.
