Starting a limestone project might seem a bit overwhelming. There are several grades of limestone to choose from, depending on the size rocks you need. We’re here to explain your options when it comes to choosing a limestone grade.
At Port Aggregates, we use top-quality white limestone that has the same durability as gray limestone, but weighs 10% less. This allows for less material to cover more space, saving you money. You will also get to choose your size range, which is where limestone gradations come into play.
We offer the following varieties that range for ¼” to 2”:
- #57 Calica (¾ – 1”)
- #89 Calica (¼ – ⅜”)
- #458 Calica (⅝ – 2”)
- #610 Calica (Powder – 1 ½”)
- #689 Calica (½ – ⅝”)
- #1×4 Kentucky (1 – 4”)
- #4 Kentucky (2 – 2 ½”)
- #7 Kentucky (⅜”)
- #8 Kentucky (¼”)
- #57 Kentucky (¾ – 1”)
- #610 Kentucky (1 – ½”)
- #610 Crushed Concrete (Powder – 1 ½”)
- 10lb Rip Rap
- 30lb Rip Rap
- 55lb Rip Rap
When mixed with aggregate concrete mixtures, crushed limestone is great to use as the top layer of a concrete driveway. Underneath the top layer, certain large grades like our #2 ½ OG is a great filler, and can be layered with #57G and topped with a finer grade like #8G limestone. #8G crushed limestone is also perfect when used as an aggregate for asphalt driveways, a drainage system to run water off of your property (⅜ – ½ inch), or as an accent around plants and other natural elements.
What are you using it for?
If you desire a loose-top driveway, a larger, denser grade (up to 1 ½ inches) like our road gravel or crushed concrete is what you’re looking for. This is a good low-maintenance choice for the top of a leveled driveway.
If your goal is to prevent erosion on a hill, slope, or pond bank, our larger grade rip rap (crushed limestone) #1x4G is ideal for this purpose, and is typically installed over a textile. A finer grade can be used beneath this as bedding. Rip rap can also be used to form low-lying or dividing walls for plants.
A pea gravel is typically used for footpaths or gardens, due to its finely crushed texture. Larger grades of crushed limestone like #57G are typically used to make base layers for these walkways, or as a landscaping filler to surround paving stones. Whatever your limestone project may be, we have just the grade you need. Request a quote today to get started!
