#67 Gravel is a crushed blue-gray granite that is dry-screened to measure roughly 3/4″, meaning the actual size of any particular piece will be from 1/2″ to 1″ long. Stone dust and pea gravel are screened out, giving you an attractive landscaping material with superb drainage qualities. This landscaping stone is pleasing to the eye. Many businesses and homeowners lay this or similar stone around their buildings to keep those areas clean, well drained and easy to maintain.
This loose, angular gravel is commonly used for backfilling drainage ditches such as French drains around buildings, and as one of the base layers under brick, stone or concrete pavers (beneath the sand layer). It provides excellent erosion control at the base of retaining walls, and is typically laid down in trenches before large pipe or culvert is placed in them.
Roads & Driveways
It is common practice to spread a few inches of #67 Gravel top of Crusher Run Gravel or ABC previously laid down on roads, driveways and parking lots. The dust-filled Crusher Run Gravel or ABC layer packs in dense and hard to resist erosion from weather and traffic while the top layer of #67 Gravel sits clean and pretty on the surface, letting the water through to the tougher layer of Crusher Run Gravel underneath.
#67 Gravel will not do as well when placed directly on soil or when spread on steep areas. It will gradually sink into dirt, especially under traffic. On a steep slope it will move in the direction of rainwater and traffic, exposing whatever is underneath. For steep ground, Crusher Run Gravel is the better choice. Even on level ground, a moisture resistant base of ABC Crusher Run Gravel or even plastic mulch is recommended to keep this chunky stone sitting pretty for many years.
