Mined Rocks
*Crushed Stone: Produced by blasting solid rock formations (like limestone, granite, or trap rock) from quarries and feeding them through heavy mechanical crushers. The resulting stones have sharp, angular edges that interlock tightly, making them the industry standard for stable construction bases (such as #57 gravel).
*Naturally Rounded Aggregates: Harvested from ancient, dry riverbeds or glacial deposits where water naturally eroded and smoothed the stones over thousands of years. These are screened by size and are highly prized for decorative ground covers (such as Colorado Rainbow River Rock or TexMex Blend).
*Rip Rap & Cobble: Chunky, heavy-duty stones mined from quarry faces to be used as erosion barriers on steep hillsides, drainage ditches, and shorelines (such as limestone rip rap).
River Rocks
Naturally occurring, water-worn stones that have been smoothly rounded by the continuous abrasive action of moving water over thousands of years. They are harvested from active or ancient riverbeds, beaches, and glacial deposits, making them one of the most popular premium choices for decorative landscaping and drainage projects.
*Smooth, Rounded Texture: Continuous water flow and friction tumble the rocks together, naturally grinding away all sharp, fractured edges.
*Diverse Color Palette: Depending on the region where they are mined, they feature rich blends of natural earth tones—such as browns, tans, creams, greys, and muted reds—that become exceptionally vibrant when wet.
*Varied Geologic Composition: A single batch of river rock is rarely made of just one mineral type. It typically contains a heavy mix of durable rocks like granite, quartz, basalt, and limestone.
Sand
The vast majority of natural construction sand is harvested from alluvial floodplains, modern riverbanks, or ancient, dry river corridors where water has naturally accumulated massive mineral sediments over millions of years. Large industrial excavators scoop out bank sand, or massive hydraulic dredges pump raw, wet sediment directly from the pit floor.
These multi-acre plants house the heavy machinery needed to refine raw earth, including multi-tier vibrating sorting decks, automated hydro-cyclones, and large hydraulic sand wash screws.
Bedrock walls of limestone, granite, or trap rock are blasted out with explosives and hauled to giant mechanical jaw and cone crushers. The machinery pulverizes the solid rock into a highly angular, sharp-edged sand matrix known as M-sand (manufactured sand).
