Crushed StonesRip Rap 3
IDOT-certified Rip Rap 3 is a large-format 9"x6" crushed stone engineered for heavy-duty erosion control, shoreline protection, and high-flow drainage applications. Built to hold its ground where it matters most.
Rip Rap 3 (IDOT Certified #022RR03) is a substantial, angular crushed stone sized at 9" x 6", purpose-built for applications where water flow, erosion, and structural integrity demand a serious solution. Its large mass and jagged profile allow it to resist displacement even under significant hydraulic forces, making it the material of choice for protecting vulnerable areas from the relentless effects of moving water.
Rip Rap 3 excels at stabilizing drainage ditches, culverts, and pipe outlets — areas where concentrated water flow can quickly erode unprotected surfaces. Along pond edges, lake shorelines, and retaining walls, its bulk and interlocking shape create a durable, long-lasting armor layer that shields the underlying soil from wave action, runoff, and undercutting. Whether managing stormwater infrastructure or protecting a natural water feature, Rip Rap 3 provides the heavy-duty erosion control performance that engineers and contractors rely on.
IDOT-certified for quality and consistency, Rip Rap 3 is a proven material for civil, municipal, and land management projects of all scales.
Common Uses: Drainage and ditches, culverts and pipe outlets, retaining walls, pond and lake edges, and erosion control.
