Slag #8

#8 slag is a clean, graded aggregate typically sized between 3/8 inch and 1/2 inch. Made from processed steel slag, this angular material provides excellent drainage while maintaining strong interlock and stability. Smaller than #2 slag, it is well suited for applications where a durable, free-draining stone is required without heavy compaction.

Its hardness and resistance to wear make it a dependable option in both structural and drainage-focused construction projects.

Common applications for #8 slag

• Concrete and asphalt mixes
• Drainage layers and trench backfill
• Pipe bedding and utility work
• Decorative and functional stone surfaces
