What is Crushed No Fines?
Crushed no fines is a single-sized aggregate without smaller particles or dust, creating an open-textured, free-draining material. This 40-80mm crushed stone provides structural support while allowing maximum water permeability. Loose tipped for bulk drainage projects.
What size is this material?
Graded 80-40 mm with no fines, creating large void spaces between stones. The single-size grading ensures consistent permeability throughout the layer. Large angular pieces provide structural stability while maintaining its drainage ability.
Where to use No Fines aggregate?
Essential for major drainage projects, soakaways, and attenuation tanks. Perfect behind retaining walls, under permeable surfaces, and in SUDS installations. This also helps by preventing hydrostatic pressure. Used in civil engineering drainage solutions.
Extra Information
The absence of fines maintains approximately 40% void space for excellent drainage. Must be laid on geotextile to prevent soil migration. Often used with perforated pipes for comprehensive drainage systems. Calculate increased volume due to void space when ordering.
