Welcome to the Limestone section of National Site Materials – your premier supplier of high-quality limestone products for construction, agriculture, landscaping, industrial applications, and more. Limestone is one of the most widely used natural resources in the world, prized for its strength, versatility, and natural beauty.
What is Limestone?
Limestone is a sedimentary rock primarily composed of calcium carbonate (CaCO₃), formed over millions of years from the accumulated remains of marine organisms like shells and coral. It is durable, workable, and available in various forms including crushed stone, aggregates, powder, and dimension blocks.
Common Names for Limestone
Limestone is known by several alternative or related names, depending on its form, composition, or specific variety:
- Lime rock
- Calcium carbonate rock
- Chalk (a soft, fine-grained form)
- Marble (metamorphosed limestone)
- Travertine
- Tufa
- Dolomitic limestone (when it contains significant magnesium)
- Crushed limestone or aggregate
All the Many Usages of LimestoneLimestone’s unique properties make it indispensable across numerous industries. Here are some of its primary applications:
- Construction and Building Materials — Crushed limestone serves as aggregate in concrete and asphalt, base material for roads and driveways, railroad ballast, and dimension stone for walls, facades, flooring, veneer, monuments, and historic structures.
- Cement Production — A key ingredient in manufacturing Portland cement, the foundation of modern infrastructure.
- Agriculture — Agricultural lime (ag lime) neutralizes acidic soils, improves pH levels, enhances nutrient availability, and boosts crop yields.
- Steel Manufacturing — Used to remove impurities during the smelting process.
- Chemical and Industrial Uses — As a feedstock for producing lime (quicklime or hydrated lime), fillers in paints, plastics, paper, toothpaste, cleansers, and more.
- Environmental Applications — Water treatment and purification, flue gas desulfurization (to reduce emissions), and neutralizing acid mine drainage.
- Landscaping and Decorative — Crushed stone for pathways, rock gardens, stepping stones, and as a durable, attractive ground cover.
- Other Uses — Glass production, mining processes (e.g., pH regulation in gold extraction), animal feed supplements, and even pharmaceuticals or cosmetics.

Frequently Asked Questions (FAQs)
- What is the difference between limestone and dolomite?
Dolomite (or dolomitic limestone) contains significant magnesium carbonate, while regular limestone is primarily calcium carbonate. Both are used similarly, but dolomite is often harder and used in specific applications like certain aggregates. - How do I know if a rock is limestone?
The simplest test is the acid test: Apply a drop of vinegar or dilute hydrochloric acid—if it fizzes or bubbles due to carbon dioxide release, it’s likely limestone (containing calcium carbonate). - Is limestone suitable for outdoor landscaping?
Yes! It’s highly durable, weather-resistant, and won’t break down easily, making it ideal for pathways, driveways, rock gardens, and decorative features. - Can limestone be used to improve my garden soil?
Absolutely. Agricultural limestone raises soil pH, reduces acidity, and helps plants absorb nutrients more effectively, leading to healthier growth and higher yields. - What sizes of crushed limestone do you offer?
We provide a wide range, from fine powder and sand-sized particles to larger rip rap and dimension stone—perfect for everything from concrete mixes to erosion control. - Is limestone environmentally friendly?
Yes, it’s a naturally occurring material with low environmental impact when sourced responsibly. It’s also used in eco-friendly applications like water treatment and reducing industrial emissions. - How quickly can you deliver limestone to my location?
Delivery times vary by quantity and distance, but we ship nationwide and work to provide fast, reliable service—often within days for many regions.
