Grenada Gravel Concrete: Concrete Products

DO YOU KNOW THE STRENGTH OF YOUR BLOCKS?

Superior construction requires high-quality materials! Gravel and Concrete is the only block supplier with a laboratory to continually test and ensure consistency in quality.

Concrete blocks that are under the physical requirements of the Grenada Bureau of Standards can compromise the structure of your building.

Our mix design, developed by our Laboratory is used in the production of our 4", 6", 8" and 12" blocks and includes Admixtures to maximize strength and are cured for at least 14 days before selling to our clients.

The required strength by the Grenada Bureau of Standards compared with the strength of Gravel and Concrete blocks after curing for fourteen (14) days are:

Block Size Bureau of Standard
14 Day Strength 		Gravel & Concrete
14 Day Strength
4" 800-1000 PSI 1099 PSI
6" 800-1000 PSI 988 PSI
8" 500-700 PSI 769 PSI
So the next time you are purchasing blocks request the strength of the blocks from your Supplier and / or the certification from the Grenada Bureau of Standards.
