Drainage Applications
Recycled #57 concrete may be appropriate for certain drainage applications when the supplied product's gradation, fines content, and other characteristics meet the requirements of the drainage system.
The #57 classification describes an aggregate size or gradation rather than every piece being one exact dimension. For drainage work, the actual material characteristics still matter because water movement depends on the void structure within the aggregate layer and how the complete drainage system is designed.
See our guide to best aggregate for Florida drainage projects for more on choosing aggregate under Florida conditions.
