Everything You Need to Know About Riprap
Size and Grading
- Size
- 4 inches to 12 inches and up
- Type
- Large, heavy stone
Muskeg and permafrost can make runoff control especially important around cabin and shop pads, gravel roads, and drainage routes. During breakup season, soft unsurfaced ground may carry water across areas that are already difficult to keep stable. RipRap supplies heavy stone cover where moving water can work into exposed soil along banks, slopes, shorelines, drainage channels, and culvert outlets.
Use RipRap on the surface that receives the water, carrying the protected cover across the exposed route instead of leaving bare ground at a bank or outlet. Its weight helps it remain where smaller aggregate could be carried away. For work that calls for smaller erosion-control stone or a heavy base layer, compare the material to those needs rather than treating it as general driveway aggregate.
