Aggregates for Construction, Drainage, and Erosion Control

Aggregates Larimer County projects frequently rely on proper stone selection because of local geology and precipitation patterns. From foothills erosion control to plains drainage, choosing the right aggregates prevents costly repairs.

Base, Sub-base, and Road Projects

Road Base and crusher run are standard for roads and heavy-use areas. Road Base compacts well and forms a strong support layer for asphalt or gravel surfaces. In our service area, road base is often used along frontage roads and private lanes that experience freeze-thaw cycles.

Driveways and Parking Areas

For durable residential driveways, our team recommends 3/4 inch Crushed Stone for the base and Driveway Gravel for the surface layer. These mixes provide stability and improved compaction on Larimer County soils.

Drainage and Foundation Rock

For French drains and subsurface systems, Drain Rock and #57 Stone ensure swift water conveyance away from foundations and slopes. Properly installed drain stone reduces hydrostatic pressure and protects basements from seasonal runoff.

Sands, Soil, and Playground Materials

Topsoil and Fill

Healthy lawns and gardens in Larimer County begin with good topsoil. Our screened Topsoil is blended for northern Colorado planting and erosion-resistant berms. Fill dirt helps regrade lots after excavation, backfill foundations, and prepare terraces in foothill properties.

Sands for Masonry and Play

We carry washed and specialty sands for masonry and play areas. Mason Sand provides a clean bedding for pavers and mortar, while Playground Sand is safe and low-dust for play structures. For bedding and drainage, Washed Sand is a versatile choice.

Decorative Stone and Landscape Rock

Larimer County landscapes range from xeric plains to mountain meadows. Our decorative aggregates help you achieve the right look while respecting local ecology.

• River Rock for dry creek beds and erosion control
• Pea Gravel for patios and play areas
• Decomposed Granite for natural-feel paths and xeriscape

Decorative rock also reduces maintenance compared with turf and provides excellent runoff control on slopes when combined with proper grading.

Recycled Materials and Eco Options

For sustainable projects, we offer Crushed Concrete and other recycled materials. These options lower embodied carbon and provide strong, compactable bases for driveways and parking areas. Recycled materials perform well on many Larimer County projects, particularly where cost and environmental impact are priorities.

Project Types Suited to Our Aggregates

Driveways and Private Roads

Use Driveway Gravel combined with a compacted sub-base of Crusher Run or Road Base for long-lasting service. These materials resist rutting through freeze-thaw cycles common on the Front Range.

Walkways and Patios

For comfortable walkways use Walkway Gravel or Pea Gravel. For a compacted, firm surface, Decomposed Granite provides a natural look and low maintenance.

Drainage and Erosion Control

Install Drain Rock or #57 Stone in French drains and behind retaining walls to redirect stormwater and protect foundations from seasonal runoff.

Ordering, Delivery, and Placement Guidance

How to Order Aggregates

Order online or by phone. We recommend measuring area square footage and depth to determine cubic yards needed. Our team can estimate quantities based on common coverage rates for each aggregate type.

Placement Tips for Larimer County Conditions

• Compact base layers in thin lifts to resist thaw-sink in spring.
• Use angular aggregates like 3/4 inch Crushed Stone or Crusher Run for load-bearing layers.
• Install drainage stone downslope to manage snowmelt and heavy rains.
• Add a clear geotextile fabric between soft soils and aggregate to reduce migration.

Local Soil, Climate, and Geology Considerations

Larimer County spans the Front Range foothills and high plains, producing a range of soil types from alluvial silt and loess on the plains to rocky colluvium in mountain valleys. Many properties face expansive clays and seasonal heaving. Choosing the right aggregates reduces maintenance and improves durability.

Climate here is semi-arid with snowy winters and strong spring runoff near the foothills and canyons. That makes proper drainage and frost-resistant base materials essential. Nearby landmarks like Rocky Mountain National Park and the Cache la Poudre River influence local hydrology and create microclimates that affect planting and drainage choices.

Nearby counties such as Weld County and Boulder County share similar aggregate needs, but mountain properties in Larimer require more attention to slope stability and erosion control.

Material Benefits and Project Matching

Benefits of Common Aggregates

• 3/4 inch Crushed Stone — strong compaction, load-bearing, economical
• #57 Stone — excellent for drainage and top dressing
• Topsoil — improves plant establishment and water retention
• Drain Rock — prevents clogging and moves water efficiently

Matching Materials to Projects

Choose materials based on load, exposure, and maintenance expectations. For example, private roads need deeper compacted road base, while decorative beds benefit from river rock or pea gravel for aesthetics and low upkeep.
