How to Choose Crushed Stone for Construction: Complete Guide

Crushed stone is one of the most important construction materials. Proper selection directly impacts the durability of any structure.

Why Selection Matters

Many beginners think crushed stone is just "rocks." However, each fraction and strength grade has its purpose.

Using the wrong material can lead to foundation cracks or rapid road deterioration.

Strength Grades

The strength grade is the key quality indicator. It's marked with M followed by a number indicating compression strength.

• M200-M400 — low strength, suitable for temporary roads.
• M1000-M1200 — high strength, ideal for foundations and concrete.

Conclusion

When choosing crushed stone, always consider the strength grade and fraction. For permanent structures, we recommend granite crushed stone with a grade of at least M1200.
