Wondering which grade of crushed limestone gravel is best for your driveway or household project? Check out the residential projects below and our guide to which types of Port Aggregate limestone aggregates are best-suited to your needs.
Driveways
Limestone Aggregate
A range of our crushed limestones works well in aggregate concrete mixtures as the top layer of concrete driveways.
Foundational Fillers
Beneath a top layer, various limestone grades form excellent driveway foundations.
- A large grade, like our #2 ½ OG fills the base;
- Next, pack on a layer of #57G;
- Then, finish off the driveway with a finer grade #8G limestone.
Loose-top Driveways
Whether used as an aesthetic choice or affordable one, there are several options in color and size.
- Grade #610S tan Calica stone and grey limestone (¾ of an inch) can serve independently as the top layer. A finer grade of one-half inch, Calica stone and grey limestone #57G, or, even finer 1/4 inch limestone #8G are also options for loose-top driveways. Both are attractive, decorative, and functional; however, be aware that the finer the grade, subsequently requires more driveway maintenance over time.
- A denser or larger grade like our crushed concrete and road gravel are more affordable, lower maintenance options for the top layer of leveled driveways. Additionally, up to 1 ½-inch grades are used for driveways.
Asphalt Driveways
Use crushed limestone #8G as an aggregate.
Landscaping and Pathways
Rip rap is a substantial enough grade that it is useful in forming low-lying walls to build planting areas or create dividing walls.
For garden or footpaths around your property, our pea gravel is finely crushed and feels pleasant underfoot. It comes in a soft blend of tan shades that make it a smart accent to an outdoor living space. We also recommend a larger grade of crushed limestone — #57G is a good option — as a base layer for walkways or landscaping filler around paving stones.
For accents around plants, trees, and landscaping features, crushed limestone #8G, a clean-crushed and washed stone, subsequently adds curb appeal.
Erosion Prevention
Our larger grade rip rap or crushed limestone, #1x4G, helps prevent erosion on pond banks, hills, and slopes. You can use one of our finer grades as bedding beneath the rip rap.
Also, crushed rip rap is typically installed over a textile. On steep slopes or in high drainage areas, a chain link fence or wire mesh is often added at the bottom of the slope to secure rip rap.
Drainage Systems
Crushed limestone #8G (3/8-1/2 inch) is ideal for channeling water runoff on your property. Several grades from 3/8-7/8 inches will do the job if the color and grade better suits the landscaping.
