Frequently Asked Questions
When should I use 3/4 gravel instead of 3/8?
3/4 gravel is used for heavy structural elements like foundations, footings, and retaining walls. 3/8 is for lighter elements like slabs and columns. The structural engineer specifies the appropriate type per design.
Can 3/4 and 3/8 gravel be mixed together?
Yes, in some concrete designs both sizes are mixed to achieve an optimal gradation that increases concrete density and strength. The mix proportions specified by the engineer must be followed.
What is 3/4" gravel and when is it used?
The largest common gravel grade (19–25 mm), used in mass concrete, heavy backfill and road bases.
3/4" vs 3/8" gravel?
3/4" is larger — for big structural work and heavy backfill; 3/8" is the standard for regular reinforced concrete.
