Granular M or ⅝” minus is the product of choice for driveways, laneways and parking areas and our best seller. It has the right blend of crushed fines with a coarse aggregate that compacts and binds together. Granular A can also be used but is recommended for higher-traffic municipal roads. Granular A is a ⅞” minus product with larger particles that have a tendency to roll to the surface and do not mesh and pack as well as the finer Granular M. This results in issues with snow blowing and snow ploughing and is less desirable to walk on.
