Compaction

Crushed limestone will settle and compact when rolled or tamped. Adding 15-20% extra material ensures you reach your target depth after compaction.

Density Variation

Crushed limestone typically weighs 2,500–3,000 lbs per cubic yard. This calculator uses 2,700 lbs/yd³ as a reasonable average. Density varies with moisture content, stone size, and compaction. Always verify with your supplier or add 10% margin for safety.

Stone Sizes

#57 is common for drainage and driveways. #411 (crusher run) is best for compactable bases under pavers or concrete.

What is Limestone?

Limestone is a crushed rock product used for construction, landscaping, agriculture, and road base. It provides drainage, stability, and aesthetic appeal in landscaping projects.

Limestone is sold by weight (pounds/tons) or volume (cubic yards). Density varies by grade: crushed limestone typically weighs 1.3-1.5 tons per cubic yard. Knowing your project area and depth helps determine quantity needed.

How to Calculate Limestone Needed

  1. Measure the length and width of your project area
  2. Determine desired depth (typically 2-4 inches)
  3. This calculator converts to cubic yards and tons
  4. Order limestone in tons or cubic yards based on supplier availability

Example: Driveway Base

Driveway: 24 feet long, 12 feet wide, 4 inches deep

Area: 288 sq ft

Result: ~0.36 cubic yards ≈ 0.5 tons (round up to 1 ton)

Frequently Asked Questions

How deep should limestone be?

Depends on use. Driveways: 4-6". Landscaping: 2-3". Base layer: 4-6". Check local guidelines.

How much does limestone weigh?

Crushed limestone: ~1.3-1.5 tons/cubic yard. Dust: lighter. Check with supplier for exact weight.

Do I need to compact limestone?

Yes, for driveways and roads. Rolling compacts limestone and improves stability. Landscaping may not require compaction.

How long does limestone last?

Weathering breaks down limestone over 5-10 years. Reapply as needed. Compacted bases last longer.

Can I mix limestone with other materials?

Yes. Limestone is often combined with gravel or asphalt base for better stability.

Where do I buy limestone?

Landscaping suppliers, quarries, home improvement stores, or bulk material dealers. Compare prices per ton.

What if I order too much or too little?

Order slightly extra (10-15%) to account for settling and spillage. Extra can be returned or stored.

Is limestone environmentally friendly?

Yes, it's a natural material. Quarrying does have environmental impact, but limestone is recyclable and widely available.

Disclaimer: Limestone calculations are estimates based on typical density (1.3-1.5 tons/cubic yard). Actual weight varies by grade, moisture, and supplier. Density affects settling and compaction. Order slightly extra (10-15%) to account for settling, spillage, and spreading. Always verify with your supplier for exact weights and availability. This calculator is for planning purposes only.
