Crushed limestone is one of the most versatile materials on the planet, and its unlimited advantages have made it quite the hot commodity among contractors of all industries.
Limestone is a very common stone that’s readily available and affordable. The possibilities are endless, and it can be used to complete almost any outdoor project. These are just a few of the many ways limestone can be used:
1. To create driveways
One of the most common uses of crushed limestone is in laying driveways. While similar to gravel in its size and texture, limestone offers a larger variety of colors to choose from and is extremely durable.
2. To regulate soil pH
Crushed limestone can be used to create aglime, an agricultural lime used to regulate soil pH by reducing its acidity. Contractors will sometimes spread it throughout newly constructed properties before sod is laid down to improve the lawn appearance. Farmers also use aglime to enhance their crop growing conditions.
3. As a road base
The bases of highways and roads must be filled with a reliable aggregate before they’re strong enough to endure the weight of traffic. This is where crushed limestone comes into play. Because of its size, strength, and affordability, it’s one of the top choices for creating a smooth and level road.
4. For pipe bedding
Did you know that crushed limestone is often used for underground pipe bedding? It’s one of the top materials for this task because it levels, supports, and protects the integrity of the pipeline. It’s also a great insulator and will not expand or contract due to environmental factors.
5. To make concrete
Concrete is made out of crushed aggregate (like limestone), water, cement, and sand. Concrete made out of limestone is extremely durable and eye-catching.
6. To prevent erosion
Crushed limestone can be used as rip rap to prevent shore erosion. Its affordability and reliability make it the ideal choice for protecting streambeds, pilings, shorelines, and bridges from ice and water damage.
7. As a railroad ballast
Railroad ballast allows water to flow away from train tracks and supports rail ties. The material chosen for these ballasts needs to be strong and angular, which is why crushed limestone is a great choice.
8. To coat roofs
When limestone is ground into a fine powder, it’s often used as a roofing and shingle coating to protect the roof and deflect heat.
9. To fill underneath slabs
Unfortunately, concrete can’t be laid down directly on the ground. It requires a layer of crushed stone, like limestone, to fill the area between the slab and the ground in order to remain level. This layer of rock also helps prevent cracking and allows for proper drainage.
