Crushed Stone

Size: 3/4" - 1"

Angular, mechanically crushed rock that compacts well and provides excellent stability. The sharp edges lock together, creating a solid base for heavy-duty applications.

Key Features:

  • Angular shape for compaction

  • Durable and long-lasting
  • Minimal migration

Best For:

Driveways, parking areas, road construction, concrete aggregate, French drains, and heavy equipment access

River Rock

Size: 1" - 3"

Large, smooth stones naturally shaped by water erosion. These attractive rocks add visual interest and texture to landscapes while providing excellent drainage.

Key Features:

  • Natural, polished appearance
  • Various color options
  • Large size prevents weed growth
  • Weather resistant
  • Low maintenance

Best For:

Landscaping accents, dry creek beds, water features, decorative borders, erosion control, and mulch alternative

Decomposed Granite

Size: 1/4" and finer

Naturally weathered granite that compacts into a firm, stable surface. Popular in New Mexico for its natural appearance and ability to blend with the desert landscape.

Key Features:

  • Natural desert aesthetic
  • Compacts firmly when wet
  • Permeable surface
  • Earthy colors (tan, brown, red)
  • Cost-effective option

Best For:

Pathways, patios, xeriscaping, natural landscapes, trails, and sustainable drainage solutions

Road Base

Size: Mixed (fines to 1.5")

Mixture of crushed stone and fines designed specifically for creating strong, stable foundations. Essential for proper road and driveway construction.

Key Features:

  • Blend of various sizes
  • Superior compaction
  • Load-bearing capability
  • Industry standard material
  • Prevents settling

Best For:

Driveway base, road construction, parking lots, under pavers, building foundations, and heavy traffic areas

Drainage Rock

Size: 3/4" - 1.5"

Clean, angular rock specifically sized for optimal water flow. Critical for managing New Mexico's intense monsoon rains and preventing erosion.

Key Features:

  • Uniform size for flow
  • Clean (minimal fines)
  • High void space
  • Prevents soil movement
  • Long-lasting performance

Best For:

French drains, foundation drainage, retaining walls, septic systems, and stormwater management

Caliche

Size: Varies

Naturally occurring New Mexico material with high calcium carbonate content. Compacts extremely well and is a traditional Southwest building material.

Key Features:

  • Native to New Mexico
  • Excellent compaction
  • Hardens when dry
  • Cost-effective
  • Weather resistant

Best For:

Rural roads, driveways, base material, erosion control, and traditional construction

Limestone Screenings

Size: 1/4" and finer

Fine limestone particles that compact into a smooth, firm surface. Popular for its clean appearance and versatility in various applications.

Key Features:

  • Fine, consistent texture
  • Bright, clean appearance
  • Excellent compaction
  • Smooth walking surface
  • Dust control when wet

Best For:

Pathways, bocce courts, under pavers, horse arenas, and garden paths
