Advantages of Granite Crushed Stone over Limestone

Is granite worth the extra cost, or can you get by with limestone? Let's find out why saving at the start can lead to enormous expenses in the future.

Why Is Granite More Expensive?

Granite crushed stone is produced from hard igneous rocks. Its extraction and processing require powerful equipment.

Limestone is a soft sedimentary rock that's easier to crush. Hence the price difference.

Durability and Strength

Granite crushed stone (grade M1200-M1400) is two to three times stronger than limestone (grade M400-M800).

In harsh climate conditions, limestone begins to deteriorate after just a few freeze-thaw cycles. Granite serves for decades.

Strength comparison:

• Granite: M1200-M1400, service life 50+ years
• Limestone: M400-M800, service life 5-10 years

Frost Resistance

Granite's frost resistance (F300-F400) allows it to withstand hundreds of freeze-thaw cycles.

Limestone actively absorbs water. When water freezes, it expands and destroys the stone from within.

In Kazakhstan's climate conditions, granite crushed stone is the only correct choice for permanent construction.

Economic Analysis

Yes, granite costs more at the purchasing stage. But factoring in replacement and repair costs, the savings are obvious.

A foundation on limestone crushed stone will need repairs in 10 years. On granite — it will last half a century.

Conclusion

For any critical structures, choose granite crushed stone grade M1200 or higher.

It's an investment in reliability and peace of mind for years to come.
