Drainage Projects
#57 limestone is commonly used for certain drainage applications where an appropriately graded aggregate provides interconnected void spaces through which water can move.
Depending on the drainage system and project requirements, it may be considered for drainage trenches, areas around drainage structures, and other applications requiring larger aggregate.
The stone itself is only one part of a functioning drainage system. Surrounding soil, filtration or separation requirements, grade, drainage pathways, and an adequate outlet can all affect performance.
See our guide to best aggregate for Florida drainage projects for more on selecting aggregate under Florida conditions.
