Erosion Control Products

Angular recycled concrete aggregate is a cost-effective alternative to quarried rip rap for protecting disturbed slopes, channels, and drainage structures from erosion. Allied Recycled Aggregates carries multiple grades suited to different flow rates and slope conditions, available by the ton and delivered across the Front Range.

3" Recycled Concrete Rock

A versatile mid-size erosion control rock that performs well across a wide range of slope and flow conditions. Free-draining with significant mass — holds position on moderate slopes and resists wash-out in swales and drainage channels.

Best for: swales, mild embankments, erosion blanket underlayment, detention pond outfalls, and tracking pads.

Price: $17.05/ton — see full pricing

1-1/2" Recycled Concrete Rock

A clean, screened aggregate with near-zero fines for applications where drainage and surface stability matter equally. Works well as a surface layer over geotextile fabric on slopes or as liner material in shallow swales and perimeter ditches.

Best for: slope stabilization over filter fabric, shallow swales, perimeter drainage, and pipe outfall protection.

Price: $17.61/ton — see full pricing

1" Recycled Concrete Rock

A compact screened aggregate sized 1" × ¾" — versatile enough for both drainage and erosion control. The smaller particle size provides a stable, even surface on gentle slopes and fits tightly around drainage structures and pipe outfalls where larger rock would leave excessive voids.

Best for: gentle slope stabilization, pipe outfall protection, shallow drainage channels, and under-slab drainage.

Price: $19.58/ton — see full pricing
