What should be the minimum thickness of limestone dust flooring for effective use?

The minimum thickness of limestone dust flooring should be between four to five inches for effective use. This thickness provides the necessary stability and durability required for flooring applications, particularly in environments where heavy equipment or consistent foot traffic is expected. A thickness of four to five inches allows for adequate compaction and support, helping to prevent cracking or settling over time.

Thinner layers, such as those falling below this range, may not provide sufficient strength or durability, leading to potential issues like uneven surfaces or increased wear and tear. Conversely, thicker layers, beyond five inches, may not be necessary for most applications and could result in wasted material and additional costs without providing significant benefits. Therefore, four to five inches is optimal for balancing effectiveness with practicality in limestone dust flooring.
