West Chester Natural Curb is a heavy duty edge restraint that has stood the test of time. You can still see this type of curbing on the city streets of Philadelphia and New York City. Our typical curb is 4″ – 5″ and snapped or guillotined to 12″. Lengths are random and go from 18″ to 48″. This product can be done in custom sizes and also used as decorative driveway aprons and parking areas.
