Frequently Asked Questions

Why is silt content important in river sand?

How is Black River Sand measured for bulk delivery?

River sand is usually measured in Brass (1 Brass = 100 Cubic Feet / approximately 4.25 Metric Tonnes depending on moisture content).

What GST rate applies to natural river sand?

Natural building sand carries a standard GST rate of 5% in India.
